Moe Biller, 87, president of the American Postal Workers Union for two decades, died on Friday.
Biller became a mail clerk in 1937. His pay was 65 cents an hour, without vacation or benefits, the Associated Press reported.
After serving in the Army during World War II, he returned to the Post Office and got involved in the union. He became president of the Manhattan-Bronx Postal Workers Union in 1959. He served in that position until becoming national president in 1980.
Biller led a strike in 1970 that led to the Post Office reorganization in 1971. Workers won the right to bargain for wages and benefits and a system was set up to avoid strikes through arbitration.
