#OTD 1919 Mass Gov #CalvinCoolidge called in the #NationalGuard to put down a contentious #BostonPD strike. As crime ran rampant in city, the soldiers used #MachineGuns on crowds, and killed near a dozen.

All 1,100 cop participants in the police #strike were fired, and #unemployed WWI #veterans replaced them. Ironically, they got higher salaries and more off-days than the fired striking cops asked for.

Coolidge's cool refusal to capitulate to #OrganizedLabor #unions made him a #ConservativeIcon and primed him for a winning #presidential run in 1920.

#RonaldReagan revered Coolidge and fired the striking #AirTrafficControllers in the 1980's near a Coolidge portrait hung prominently in the #WhiteHouse.
