James P. Hoffa Sean O'Brien The 2021 leadership election for the International Brotherhood of Teamsters occurred after the General President James P. Hoffa announced his retirement.

[1][2] On November 19, 2021, Sean O'Brien of the Teamsters United slate was declared the winner.

The Teamsters United slate, led by O'Brien of Local 25 in Boston and Fred Zuckerman of Local 89 in Louisville, is aligned with a reform movement within the Teamsters Union.

[1] Some of the same groups behind Teamsters United ran a slate in 2016 that narrowly lost to Hoffa.

The internal rank-and-file organization Teamsters for a Democratic Union campaigned in favor of Teamsters United, on the basis of dissatisfaction around issues including contract negotiations and pension arrangements.
