WASHINGTON — There has been a doubling of petitions by workers to have union representation during President Joe Biden’s administration, according to figures released Tuesday by the National Labor Relations Board.

There were 3,286 petitions filed with the government in fiscal 2024, up from 1,638 in 2021. This marks the first increase in unionization petitions during a presidential term since the Ford administration, which ended 48 years ago. In former President Donald Trump’s one term, union petitions declined 22%.

Biden said in a statement that the increase showed that his administration has done more for workers than his predecessor — Trump, the current Republican nominee who is vying to return to the White House in November’s election.

“After the previous administration sided with big corporations to undermine workers — from blocking overtime pay protections to making it harder to organize — my administration has supported workers,” Biden said. “Because when unions do well, all workers do well and the entire economy benefits.”

Vice President Kamala Harris, the Democratic presidential nominee, is relying heavily on union support to help turn out voters in this year’s presidential election.

Just 16% of voters in 2020 belonged to a union household. Biden secured 56% of them, compared to Trump getting 42%, according to AP VoteCast.

Workers also have become more empowered to report what they judge to be unfair labor practices. The National Labor Relations Board said its field offices received a total of 24,578 cases last fiscal year, the most in more than a decade.
