Michigan Federation of Labor formed. The country's first major auto strike takes place when 3,500 workers walk out of the Studebaker Motors Plant at West Jefferson and Clark in Detroit. Briggs makes a few concessions, but most demands are ignored. Half the workers are fired.
Police attack striking workers.
They retaliate by storming eight shops in Detroit, burning blueprints and tool diagrams. The six-week strike ends with modest employee gains. They occupy if for 44 days, fighting off an assault by police. When GM rapidly falls behind in sales, it agrees to settle and negotiate a national contract. At the time, this was considered the largest victory in union history.
