In mid-November, the International Brotherhood of Teamsters (IBT) will count the votes to determine who will lead North America’s logistics union for the next five years. Whoever wins will have two enormous items at the top of their to-do list: scaling up logistics organizing, including at Amazon, and bargaining the country’s largest private-sector union contract, UPS.

Current general president James P. Hoffa, son of the legendary Jimmy Hoffa, is retiring after more than two decades in leadership. The two slates vying to replace him have been campaigning for nearly two years, with a petition accreditation process last fall and the nominating convention in June.

Unlike in most unions, all 1.3 million Teamsters in the United States and Canada are eligible to vote directly for the top leadership positions — a reform that members won in 1991 as part of a government consent deal to stamp out corruption. Ballots were mailed out October 4.
