U.S. postal strike – largest Wildcat strikes in U.S. history (3/18/70)

The U.S. postal strike of 1970 was an eight-day strike by federal postal workers in March 1970. The strike began in New York City and spread to some other cities in the following two weeks. This strike against the federal government, regarded as illegal, was the largest wildcat strike in U.S. history.

President Richard Nixon called out the United States armed forces and the National Guard in an attempt to distribute the mail and break the strike.

The strike influenced the contents of the Postal Reorganization Act of 1970, which dissolved the United States Post Office Department, replaced it with the more corporate United States Postal Service, and guaranteed collective bargaining rights for postal workers (though not the right to strike).
