They still want to negotiate before going on strike.

Joe Biden negotiated only with the railroad companies. His attempt to throw railroad workers under the train has failed. The union voted against accepting his deal. "Press reports made it seem like the deal would create 3 sick days for railroad workers. But once the actual language came out, what was created turned out to be something less than sick time: heavily circumscribed, unpaid time off for routine or preventative medical appointments, on a Tuesday, Wednesday or Thursday with at least 30 days' notice, plus no attendance penalties for hospitalization or surgery." said Jonah Furman from Labor Notes. Also, a proposed pay raise doesn't come close to keeping up with inflation while the companies have plenty of money to donate to capitalist Democrats like Biden & Pelosi.
