The lip service given in supporting unions was belied by how Biden fucked over the railroad workers.

This is a lie that has been repeated time and time again. He fast followed the end of the strike with helping the workers get exactly what they wanted. He aided their negotiations AND got our supply lines back on line.

Nope, I did my homework on that one before posting it. From https://en.wikipedia.org/wiki/2022_United_States_railroad_labor_dispute :

In September 2022, U.S. Senators Richard Burr and Roger Wicker introduced a bill that would have required labor unions to agree to the terms proposed by the Presidential Emergency Board, to prevent a strike. It was blocked by Senator Bernie Sanders, who noted that freight rail workers receive a "grand total of zero sick days" while railroad companies made significant profits. In the House of Representatives, Speaker Nancy Pelosi said, "We’d rather see negotiations prevail so there’s no need for any actions from Congress."

In late November, after some unions had rejected the agreement, Biden asked Congress to pass the agreement into law. On November 30, the House of Representatives passed the existing tentative agreement along with an amended version that would require railroad employers to ensure 7 days paid sick leave. On December 1, the Senate passed the tentative agreement with only 1 day of sick leave. President Joe Biden signed the legislation into law on December 2. The Biden administration's intervention in the dispute was condemned by over 500 labor historians in an open letter to Joe Biden and Secretary of Labor Marty Walsh.

Biden may not have aggressively attacked and ruined the railroad workers the way Reagan did with the air traffic controllers, but he definitely forced them to take less than they would've gotten if they'd been allowed to strike.
