It's notable whenever the International Brotherhood of Teamsters elects a new president, but it was especially notable last month when Sean O'Brien soundly defeated a rival backed by the union's outgoing president, James P. Hoffa.

During the campaign, O'Brien portrayed himself as an outsider and said the Teamsters should take a more aggressive stance—particularly toward Amazon Inc.

O'Brien granted a post-election interview to Bloomberg Law's Ian Kullgren. And in this episode of our weekly legal news podcast, On The Merits, Kullgren asks O'Brien about his plans to take on the e-commerce giant and his relationship to Labor Secretary, and fellow Bostonian, Marty Walsh. President-Elect O'Brien will lead the union starting in March 2022.
