1937 New York City department store strikes
During the 1937 New York City department store strikes over 100 department store workers participated in a sit-down strike in New York City. In an interview with a worker from the Federal Writers' Project (an agency of the Works Progress Administration), department store clerk Irving Fajans talked about the sit-in strikers – with demands of a forty-hour work week and higher hourly wages—and their twelve-day occupation of five New York City chain department stores.
