More workers voted to certify unions this year than they have in the past 15 years.

Leading up to November’s election, both President-elect Donald Trump and Vice President Kamala Harris courted a variety of unions to rally supporters. The largest union in the nation, the Teamsters, opted not to endorse either candidate for president after a long tradition of endorsing the Democratic candidate, which the Trump campaign counted as a win for their side. Meanwhile, the United Auto Workers endorsed Harris after endorsing President Joe Biden when he was still in the running.
