A sweatshop or sweat factory is a crowded workplace with very poor or illegal working conditions. The manual workers are poorly paid, work long hours, and experience poor working conditions. Some illegal working conditions include poor ventilation, little to no breaks, inadequate work space, insufficient lighting, or uncomfortably/dangerously high or low temperatures. The work may be difficult, tiresome, dangerous, climatically challenging, or underpaid. Workers in sweatshops may work long hours with unfair wages, regardless of laws mandating overtime pay or a minimum wage; child labor laws may also be violated. Women make up 85 to 90% of sweatshop workers and may be forced by employers to take birth control and routine pregnancy tests to avoid supporting maternity leave or providing health benefits.

A minimum wage is the lowest remuneration that employers can legally pay their employees—the price floor below which employees may not sell their labor. Most countries had introduced minimum wage legislation by the end of the 20th century. Because minimum wages increase the cost of labor, companies often try to avoid minimum wage laws by using gig workers, by moving labor to locations with lower or nonexistent minimum wages, or by automating job functions. Minimum wage policies can vary significantly between countries or even within a country, with different regions, sectors, or age groups having their own minimum wage rates. These variations are often influenced by factors such as the cost of living, regional economic conditions, and industry-specific factors.
