U.S. postal workers began an eight-day strike after Congress raised their wages by only 4 percent despite increasing its own pay by 41 percent.

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.

The United States Congress is the legislative branch of the federal government of the United States. It is a bicameral legislature, including a lower body, the U.S. House of Representatives, and an upper body, the U.S. Senate. They both meet in the United States Capitol in Washington, D.C.
