Speaking from the Pennsylvania A.F.L.-C.I.O. headquarters in Harrisburg, Joseph R. Biden Jr. told union members he would be “the strongest labor president you have ever had” and gave a blistering condemnation of President Trump, calling him “downright un-American” for reportedly describing fallen service members as “losers” and “suckers.”

This Labor Day, America’s working families are facing unprecedented challenges.

COVID-19 continues to ravage our communities, with thousands falling ill and hundreds dying every day. More than 27 million people are receiving some form of unemployment assistance in the worst economic crisis since the Great Depression, with job losses hitting women and workers of color hardest of all.

A lack of poll workers can lead to a lack of available polling places ― and voter disenfranchisement. Given that the pandemic has made door-knocking infeasible in so many areas, labor groups are diverting some of that energy and resources to the poll worker cause. “With COVID, door-to-door has gone by the wayside.

Richard Trumka, the president of the AFL-CIO, on Thursday morning accused President Trump of breaking his promises to bring more manufacturing and infrastructure jobs to working Americans.

Streaming from Milwaukee, Democratic National Committee Chair Tom Perez touched on the recent appointment of Republican megadonor and Trump loyalist Louis DeJoy as postmaster general and the president’s other tactics against the Postal Service in Monday’s council meeting, calling out “a postmaster general who has no business being there” and “a president who knows he can’t win on the up and up, so he knows he has to cheat.”

AFL-CIO President Richard Trumka delivered the following remarks at the 2020 Democratic National Convention Labor Council Meeting:

I want to thank my longtime friend, Brother Stuart [Appelbaum], for that introduction. And I want to thank Chairman [Tom] Perez, for his great leadership. 

UNITE HERE’s Culinary Union, the strongest political force in the state, ran an aggressive political effort during the Nevada Primary. The Culinary Union mobilized thousands of hospitality workers, immigrant, and Black voters to win primaries for candidates who will fight for our families.

The AFL-CIO, the country’s largest coalition of labor unions, endorsed Joe Biden for president Tuesday, with the organization’s top official vowing to wage an aggressive effort to help him defeat President Trump by reaching out to working-class voters.
