John T. "Jack" Joyce (December 6, 1935 – February 14, 2013) was an American labor union leader.
He then returned to Chicago, working for the Masonry Institute of Cook County, then becoming administrator of various funds for the bricklayers' union local.
He served as a vice-president of the AFL-CIO from 1984, and also on the executive of the International Confederation of Free Trade Unions, in which role he argued that construction unions in poorer countries should link training programs to affordable housing.
He also argued for co-operation between construction unions in the United States, and was a strong supporter of Robert Georgine.
[1][2] In 1998, Joyce ran for re-election, and defeated the union's secretary-treasurer, L. Gerald Carlisle.
