John F. Griner (August 7, 1907 – April 22, 1974) was an American labor union leader.
Born in Camilla, Georgia, Griner went to work on the railroads in 1925, and joined both the Order of Railroad Telegraphers and the American Train Dispatchers Association.
In 1936, he began working for the Railroad Retirement Board, rising to become its labor relations officer, and he joined the American Federation of Government Employees (AFGE).
The union also voted to remove a no strike clause from its constitution, against Griner's wishes.
[2] In 1969, he was also elected as a vice-president of the AFL-CIO,[2] and in 1971 he was the federation's delegate to the British Trades Union Congress.
