New York City
The City of New York called either New York City or New York, is the most populous city in the United States. With an estimated 2017 population of 8,622,698 distributed over a land area of about 302.6 square miles, New York is the most densely populated major city in the United States. Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, the largest metropolitan area in the world by urban landmass and one of the world's most populous megacities, with an estimated 20,320,876 people in its 2017 Metropolitan Statistical Area and 23,876,155 residents in its Combined Statistical Area. A global power city, New York City has been described as the cultural and media capital of the world, exerts a significant impact upon commerce, research, education, tourism, art and sports; the city's fast pace has inspired the term New York minute. Home to the headquarters of the United Nations, New York is an important center for international diplomacy.
Situated on one of the world's largest natural harbors, New York City consists of five boroughs, each of, a separate county of the State of New York. The five boroughs – Brooklyn, Manhattan, The Bronx, Staten Island – were consolidated into a single city in 1898; the city and its metropolitan area constitute the premier gateway for legal immigration to the United States. As many as 800 languages are spoken in New York, making it the most linguistically diverse city in the world. New York City is home to more than 3.2 million residents born outside the United States, the largest foreign-born population of any city in the world. In 2017, the New York metropolitan area produced a gross metropolitan product of US$1.73 trillion. If greater New York City were a sovereign state, it would have the 12th highest GDP in the world. New York is home to the highest number of billionaires of any city in the world. New York City traces its origins to a trading post founded by colonists from the Dutch Republic in 1624 on Lower Manhattan.
The city and its surroundings came under English control in 1664 and were renamed New York after King Charles II of England granted the lands to his brother, the Duke of York. New York served as the capital of the United States from 1785 until 1790, it has been the country's largest city since 1790. The Statue of Liberty greeted millions of immigrants as they came to the U. S. by ship in the late 19th and early 20th centuries and is an international symbol of the U. S. and its ideals of liberty and peace. In the 21st century, New York has emerged as a global node of creativity and entrepreneurship, social tolerance, environmental sustainability, as a symbol of freedom and cultural diversity. Many districts and landmarks in New York City are well known, with the city having three of the world's ten most visited tourist attractions in 2013 and receiving a record 62.8 million tourists in 2017. Several sources have ranked New York the most photographed city in the world. Times Square, iconic as the world's "heart" and its "Crossroads", is the brightly illuminated hub of the Broadway Theater District, one of the world's busiest pedestrian intersections, a major center of the world's entertainment industry.
The names of many of the city's landmarks and parks are known around the world. Manhattan's real estate market is among the most expensive in the world. New York is home to the largest ethnic Chinese population outside of Asia, with multiple signature Chinatowns developing across the city. Providing continuous 24/7 service, the New York City Subway is the largest single-operator rapid transit system worldwide, with 472 rail stations. Over 120 colleges and universities are located in New York City, including Columbia University, New York University, Rockefeller University, which have been ranked among the top universities in the world. Anchored by Wall Street in the Financial District of Lower Manhattan, New York has been called both the most economically powerful city and the leading financial center of the world, the city is home to the world's two largest stock exchanges by total market capitalization, the New York Stock Exchange and NASDAQ. In 1664, the city was named in honor of the Duke of York.
James's older brother, King Charles II, had appointed the Duke proprietor of the former territory of New Netherland, including the city of New Amsterdam, which England had seized from the Dutch. During the Wisconsinan glaciation, 75,000 to 11,000 years ago, the New York City region was situated at the edge of a large ice sheet over 1,000 feet in depth; the erosive forward movement of the ice contributed to the separation of what is now Long Island and Staten Island. That action left bedrock at a shallow depth, providing a solid foundation for most of Manhattan's skyscrapers. In the precolonial era, the area of present-day New York City was inhabited by Algonquian Native Americans, including the Lenape, whose homeland, known as Lenapehoking, included Staten Island; the first documented visit into New York Harbor by a European was in 1524 by Giovanni da Verrazzano, a Florentine explorer in the service of the French crown. He named it Nouvelle Angoulême. A Spanish expedition led by captain Estêvão Gomes, a Portuguese sailing for Emperor Charles V, arrived in New York Harbor in January 1525 and charted the mouth of the Hudson River, which he named Río de San Antonio.

Civil engineering is a professional engineering discipline that deals with the design and maintenance of the physical and built environment, including public works such as roads, canals, airports, sewerage systems, structural components of buildings, railways. Civil engineering is traditionally broken into a number of sub-disciplines, it is considered the second-oldest engineering discipline after military engineering, it is defined to distinguish non-military engineering from military engineering. Civil engineering takes place in the public sector from municipal through to national governments, in the private sector from individual homeowners through to international companies. Civil engineering is the application of physical and scientific principles for solving the problems of society, its history is intricately linked to advances in the understanding of physics and mathematics throughout history; because civil engineering is a wide-ranging profession, including several specialized sub-disciplines, its history is linked to knowledge of structures, materials science, geology, hydrology, environment and other fields.
Throughout ancient and medieval history most architectural design and construction was carried out by artisans, such as stonemasons and carpenters, rising to the role of master builder. Knowledge was retained in guilds and supplanted by advances. Structures and infrastructure that existed were repetitive, increases in scale were incremental. One of the earliest examples of a scientific approach to physical and mathematical problems applicable to civil engineering is the work of Archimedes in the 3rd century BC, including Archimedes Principle, which underpins our understanding of buoyancy, practical solutions such as Archimedes' screw. Brahmagupta, an Indian mathematician, used arithmetic in the 7th century AD, based on Hindu-Arabic numerals, for excavation computations. Engineering has been an aspect of life since the beginnings of human existence; the earliest practice of civil engineering may have commenced between 4000 and 2000 BC in ancient Egypt, the Indus Valley Civilization, Mesopotamia when humans started to abandon a nomadic existence, creating a need for the construction of shelter.
During this time, transportation became important leading to the development of the wheel and sailing. Until modern times there was no clear distinction between civil engineering and architecture, the term engineer and architect were geographical variations referring to the same occupation, used interchangeably; the construction of pyramids in Egypt were some of the first instances of large structure constructions. Other ancient historic civil engineering constructions include the Qanat water management system the Parthenon by Iktinos in Ancient Greece, the Appian Way by Roman engineers, the Great Wall of China by General Meng T'ien under orders from Ch'in Emperor Shih Huang Ti and the stupas constructed in ancient Sri Lanka like the Jetavanaramaya and the extensive irrigation works in Anuradhapura; the Romans developed civil structures throughout their empire, including aqueducts, harbors, bridges and roads. In the 18th century, the term civil engineering was coined to incorporate all things civilian as opposed to military engineering.
The first self-proclaimed civil engineer was John Smeaton. In 1771 Smeaton and some of his colleagues formed the Smeatonian Society of Civil Engineers, a group of leaders of the profession who met informally over dinner. Though there was evidence of some technical meetings, it was little more than a social society. In 1818 the Institution of Civil Engineers was founded in London, in 1820 the eminent engineer Thomas Telford became its first president; the institution received a Royal Charter in 1828, formally recognising civil engineering as a profession. Its charter defined civil engineering as:the art of directing the great sources of power in nature for the use and convenience of man, as the means of production and of traffic in states, both for external and internal trade, as applied in the construction of roads, aqueducts, river navigation and docks for internal intercourse and exchange, in the construction of ports, moles and lighthouses, in the art of navigation by artificial power for the purposes of commerce, in the construction and application of machinery, in the drainage of cities and towns.
The first private college to teach civil engineering in the United States was Norwich University, founded in 1819 by Captain Alden Partridge. The first degree in civil engineering in the United States was awarded by Rensselaer Polytechnic Institute in 1835; the first such degree to be awarded to a woman was granted by Cornell University to Nora Stanton Blatch in 1905. In the UK during the early 19th century, the division between civil engineering and military engineering, coupled with the demands of the Industrial Revolution, spawned new engineering education initiatives: the Class of Civil Engineering and Mining was founded at King's College London in 1838 as a response to the growth of the railway system and the need for more qualified engineers, the private College for Civil Engineers in Putney was established in 1839, the UK's first Chair of Engineering was established at the University of Glasgow in 1840. Civil engineers possess an academic degree in civil engineering; the length of study is three to five years, the completed degree is designated as a bachelor
Massachusetts General Hospital
Massachusetts General Hospital is the original and largest teaching hospital of Harvard Medical School and a biomedical research facility located in the West End neighborhood of Boston, Massachusetts. It is the third oldest general hospital in the United States. With Brigham and Women's Hospital, it is one of the two founding members of Partners HealthCare, the largest healthcare provider in Massachusetts. Massachusetts General Hospital conducts the largest hospital-based research program in the world, with an annual research budget of more than $900 million, it is ranked as the #4 hospital in the United States by U. S. News & World Report. In November 2017, The Boston Globe ranked MGH 5th place of top workplaces, of Massachusetts companies with over 1,000 employees, this was up from 6th place in 2016. Founded in 1811, the original hospital was designed by the famous American architect Charles Bulfinch, it is the third-oldest general hospital in the United States. John Warren, Professor of Anatomy and Surgery at Harvard Medical School, spearheaded the move of the medical school to Boston.
Warren's son, John Collins Warren, a graduate of the University of Edinburgh Medical School, along with James Jackson, led the efforts to start the Massachusetts General Hospital, proposed in 1810 by Rev. John Bartlett, the Chaplain of the Almshouse in Boston; because all those who had sufficient money were cared for at home, Massachusetts General Hospital, like most hospitals that were founded in the 19th century, was intended to care for the poor. During the mid-to-late 19th century, Harvard Medical School was located adjacent to Massachusetts General Hospital. Walter J. Dodd established the radiology department at the hospital. From just after the discovery of x-rays in 1895, until his early death in 1916 from metastatic cancer caused by multiple radiation cancers he oversaw the radiology department, he underwent over 50 surgical procedures at the hospital to treat his radiation injuries, from skin grafts to amputations. The first American hospital social workers were based in the hospital.
The hospital's work with developing specialized computer software systems for medical use in the 1960s led to the development of the MUMPS programming language, which stands for "Massachusetts General Hospital Utility Multi-Programming System," an important programming language and data-base system used in medical applications such as patient records and billing. A major patient database system called File Manager, developed by the Veterans Administration, was created using this language. Patients, hospital staff, members of the public can learn more about the accomplishments MGH is most proud of at the Paul S. Russell, MD Museum of Medical History and Innovation, located at the front of the hospital's main campus on Cambridge Street, it was in the Ether Dome of MGH in October 1846, that a local dentist, William Thomas Green Morton, was invited to perform a public demonstration of the administration of inhaled ether to produce insensibility to pain during surgery. Several years prior, Dr. Crawford Long of Danielsville, Georgia had given ether for surgery, but his work was unknown outside Georgia until he published his experience in 1849.
On 16 October 1846, after administration of ether by Morton, MGH Chief of Surgery, John Collins Warren, painlessly removed a tumor from the neck of a local printer, Edward Gilbert Abbott. Upon completion of the procedure, without screaming or restraint, the skeptical Warren quipped, "Gentlemen, this is no humbug." News of this "anesthesia" invention traveled within months around the world. A reenactment of the Ether Dome event was painted in 2000 by Lucia Prosperi, they used the then-MGH staff to pose as their counterparts from 1846. The Ether Dome still is open to the public. An anesthesia department was established at the MGH in 1936 under the leadership of Henry Knowles Beecher. On May, 1962, under the direction of Ronald A. Malt, a team of surgeons accomplished the first replantation of severed limb. While attempting to hitch a ride on the back of a freight train, Everett Knowles hit an abutment when the train lurched, severing his arm at the shoulder, he and his arm were rushed to MGH. Some doctors prepared Everett for surgery.
First they rejoined the "chaotically mangled blood vessels the bone and the skin." In the time since the accident, the arm had grown a "deathly gray," but grew pink as the surgery progressed and blood vessels were reattached. The nerves would be reconnected in a surgery.“All we did,” said the modest Dr. Malt, “was apply techniques we’ve known about for a long time and never had occasion to correlate before…The astonishing thing was not the newness of the operation but the teamwork—the way 12 doctors with expert skills, distinguished a collection of authorities as you could find anywhere, were willing to stand by and feed the incomparable extent of their knowledge to me, for no gain other than to know they had contributed.” The main MGH campus is located at 55 Fruit Street in Massachusetts. It has expanded into an area known as the West End, adjacent to the Charles River and Beacon Hill; the hospital handles around 1.5 million outpatient visits each year at its main campus, as well as its seven satellite facilities in Boston at Back Bay, Chelsea, Revere and Danvers.
With more than 25,000 employees, the hospital is the largest non
Qatar the State of Qatar, is a country located in Western Asia, occupying the small Qatar Peninsula on the northeastern coast of the Arabian Peninsula. Whether the sovereign state should be regarded as a constitutional monarchy or an absolute monarchy is disputed, its sole land border is with neighbouring Gulf Cooperation Council monarchy Saudi Arabia to the south, with the rest of its territory surrounded by the Persian Gulf. An arm of the Persian Gulf separates Qatar from the nearby Bahrain. In early 2017, Qatar's total population was 2.6 million: 313,000 Qatari citizens and 2.3 million expatriates. Islam is the official religion of Qatar; the country has the highest per capita income in the world. Qatar is classified by the UN as a country of high human development and is regarded as the most advanced Arab state for human development. Qatar is a high-income economy, backed by the world's third-largest natural gas reserves and oil reserves. Qatar has been ruled by the House of Thani since Mohammed bin Thani signed a treaty with the British in 1868 that recognised its separate status.
Following Ottoman rule, Qatar became a British protectorate in the early 20th century until gaining independence in 1971. In 2003, the constitution was overwhelmingly approved in a referendum, with 98% in favour. In the 21st century, Qatar emerged as a significant power in the Arab world both through its globally expanding media group, Al Jazeera Media Network, supporting several rebel groups financially during the Arab Spring. For its size, Qatar wields disproportionate influence in the world, has been identified as a middle power. Qatar is the subject of a diplomatic and economic embargo by Saudi Arabia, the United Arab Emirates and Egypt, which began in June 2017. Saudi Arabia has proposed the construction of the Salwa Canal, which would run along the Saudi-Qatar border turning Qatar into an island. Pliny the Elder, a Roman writer, documented the earliest account pertaining to the inhabitants of the peninsula around the mid-first century AD, referring to them as the Catharrei, a designation which may have derived from the name of a prominent local settlement.
A century Ptolemy produced the first known map to depict the peninsula, referring to it as Catara. The map referenced a town named "Cadara" to the east of the peninsula; the term'Catara' was used until the 18th century, after which'Katara' emerged as the most recognised spelling. After several variations -'Katr','Kattar' and'Guttur' - the modern derivative Qatar was adopted as the country's name. In Standard Arabic, the name is pronounced. Human habitation of Qatar dates back to 50,000 years ago. Settlements and tools dating back to the Stone Age have been unearthed in the peninsula. Mesopotamian artifacts originating from the Ubaid period have been discovered in abandoned coastal settlements. Al Da'asa, a settlement located on the western coast of Qatar, is the most important Ubaid site in the country and is believed to have accommodated a small seasonal encampment. Kassite Babylonian material dating back to the second millennium BC found in Al Khor Islands attests to trade relations between the inhabitants of Qatar and the Kassites in modern-day Bahrain.
Among the findings were 3,000,000 crushed snail shells and Kassite potsherds. It has been suggested that Qatar is the earliest known site of shellfish dye production, owing to a Kassite purple dye industry which existed on the coast. In 224 AD, the Sasanian Empire gained control over the territories surrounding the Persian Gulf. Qatar played a role in the commercial activity of the Sasanids, contributing at least two commodities: precious pearls and purple dye. Under the Sasanid reign, many of the inhabitants in Eastern Arabia were introduced to Christianity following the eastward dispersal of the religion by Mesopotamian Christians. Monasteries were constructed and further settlements were founded during this era. During the latter part of the Christian era, Qatar comprised a region known as'Beth Qatraye'; the region was not limited to Qatar. In 628, Muhammad sent a Muslim envoy to a ruler in Eastern Arabia named Munzir ibn Sawa Al Tamimi and requested that he and his subjects accept Islam. Munzir obliged his request, accordingly, most of the Arab tribes in the region converted to Islam.
After the adoption of Islam, the Arabs led the Muslim conquest of Persia which resulted in the fall of the Sasanian Empire. Qatar was described as a famous camel breeding centre during the Umayyad period. In the 8th century, it started benefiting from its commercially strategic position in the Persian Gulf and went on to become a centre of pearl trading. Substantial development in the pearling industry around the Qatari Peninsula occurred during the Abbasid era. Ships voyaging from Basra to India and China would make stops in Qatar's ports during this period. Chinese porcelain, West African coins and artefacts from Thailand have been discovered in Qatar. Archaeological remains from the 9th century suggest that Qatar's inhabitants used greater wealth to construct higher quality homes and public buildings. Over 100 stone-built houses, two mosques, an Abbasid fort were constructed in Murwab during this period. However, when the caliphate's prosperity declined in Iraq, so too did it in Qatar. Qatar is mentioned in 13th-century Muslim scholar Yaqut al-Hamawi's book, Mu'jam Al-Buldan, which alludes to the Qataris' fine striped wov

The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
A laborer or labourer is a person who works in the construction trades, by tradition, manual labor. Laborers are employed in the construction industry, such as road paving, bridges, railway tracks. Laborers work with blasting tools, hand tools, power tools, air tools, small heavy equipment, act as assistants to other trades as well, such as operators or cement masons; the 1st century BC engineer Vitruvius writes about laborer practices at that time. Other than the addition of pneumatics, laborer practices have changed little. With the advent of advanced technology and its introduction into the construction field, the laborers have been quick to include much of this technology as being laborers work; the following tools are considered a minimum for a laborer to keep with them: hammer, pliers w/ side-cutters, utility knife, tape measure, locking pliers, crescent wrench, margin trowel, carpenter's pencil or soapstone, tool belt and one pouch. In addition: a five gallon bucket with additional tools, toolbelt suspenders, water jug and lunchbox are recommended.
Most safety equipment, consumed or work specific, for example hard hat, safety glasses, hearing protection, fall protection, high-visibility clothing, concrete boots, respirator/dust mask and toe guards are provided by the employer as part of construction site safety. Personal safety equipment, for example full leather boots, high strength pants - Carhartt or jeans - socks, lip balm, climate specific outerwear, are provided by the individual; some of the work done by laborers includes: concrete - shotcrete, gunite and steel forms demolition - concrete cutting, pavement breaking, cutting torch environmental remediation and hazardous waste fences and landscaping street sweeping hod carrier - block masonry and fireproofing paving - white paving formwork, traffic control, signs piping - water pipe and storm drain field technology general digging tunnels - drilling and blasting dry utilities - electrical conduit and communications conduit loading and offloading - handling of physical goods, such as construction materials As a manual labor occupation, to attract free workers the wages paid to laborers is higher than those paid in general to unskilled workers.
In the United States, a union laborer earns equal or greater than most work available to anyone with a bachelor's degree. This is one of a few fields where someone without a high school diploma can still earn a living wage. Union, heavy construction and highway construction laborers earn on average $25.47/h compared to 13.72/h for non-union laborers. In addition to paid earnings, union laborers enjoy the benefits of medical insurance, vacation pay, pension plans and vocational schools, it is not uncommon for young civil engineers, construction managers and construction engineers typical salary of 40,000 to 60,000 to fall short of their union laborers average wages of 50,000 to 80,000. However, unlike engineers, laborers are not employed full-time year round and face significant hazards; the additional pay laborers receive is balanced out by the lesser unemployment checks they receive while out of work and the disability checks they receive while injured—often debilitated for life. That is if unemployment and injury insurance is provided, not the case.
Engineers are not immune to being out of work. In heavy civil work some are employed on a project basis and mental injuries due to stress are a different but debilitating hazard; because of the wide range of skills and ability to provide muscle, laborers earn side-work as independent contractors and under-the-table work. In construction the pay for laborers is low enough that planning problems can be solved by "throwing laborers at it." This can become a toxic and dangerous brew of unplanned work that slides forward on the blood and sweat of hard working laborers—injury rates soar. The value of work put in place by laborers and the value of avoided rework and increased efficiencies produced by the engineers' planning is a balance of resource utilization on any large project. Union laborers earn more than unfree labor and can be an avenue for those who are uneducated and with no resources to become educated and with resources. There are dangers associated with laboring. Many laborers are injured or killed in accidents each year while performing work duties.
Many who work as laborers for a short period of time will suffer from permanent work injuries such as: hearing loss, osteoarthritis, back injuries, eye injury, head injury, chemical burn, lung disease, missing finger nails and skin scars. Alcoholism, drug use, drug abuse are common although most companies require drug screening for all new hires. If a laborer is injured on the job they are given a drug test. If the test results are positive they are ineligible for any Workers' compensation benefits. There is a gray area for the use of marijuana due to medical marijuana prescriptions; some who have been dismissed for failing a drug test while possessing a prescription have been reinstated with pay as having been wrongfully terminated. The Laborers' Internatio
