Post Strike NYC 1970

New York City postal workers picket the General Post Office.

The first mass work stoppage in the 195-year history of the Postal Service began on March 18, 1970, with a walkout of letter carriers in Brooklyn and Manhattan who were demanding better wages.

Ultimately, 210,000 (in 30 cities) of the nation’s 750,000 postal employees participated in the wildcat strike.

With mail service virtually paralyzed in New York, Detroit, and Philadelphia, President Nixon declared a state of national emergency and assigned military units to New York City post offices.

The stand-off ended one week later.
