Memphis sanitation strike

The Memphis sanitation strike began on February 12, 1968, in response to the deaths of sanitation workers Echol Cole and Robert Walker. The deaths served as a breaking point for more than 1,300 African American men from the Memphis Department of Public Works as they demanded higher wages, time and a half overtime, dues check-off, safety measures, and pay for the rainy days when they were told to go home.
