The 2020 Michigan graduate students' strike was a labor strike launched by the Graduate Employees' Organization 3550, the graduate student employee union that represents approximately 2,100 graduate student instructors at the University of Michigan in Ann Arbor, Michigan, United States. The main cause of the strike was related to graduate students' objection to the university's plans for reopening during the COVID-19 pandemic. Additional calls were made by the union for defunding the campus police. The strike started on September 8, 2020, and was scheduled to last for four days, with a subsequent vote extending the strike for another week. Following the start of the strike, resident assistants and student employees for the university's dining services announced they would also strike over similar concerns regarding the university's COVID-19 policies.
