Where was a sit-down strike first used?

The sit-down strike was first notably used in the United States during the General Motors sit-down strike in 1936-1937 in Flint, Michigan. This form of protest involved workers occupying their workplace and refusing to leave until their demands were met, effectively halting production. The tactic was significant in the labor movement, as it helped strengthen the United Auto Workers union and led to better working conditions and wages for many workers.
