I think you're confusing the rail labor bills with the Omnibus bill, but anyway:

that was filibustered by Republicans

Who participated in this "filibuster", and who voted against cloture?
Seems like Congress and the President should have put forward a more labor friendly agreement.  But I guess we knew that a few weeks back.
Edit: I should mention for clarity that the more labor friendly provisions were all blocked by Republicans. >


the more labor friendly provisions were all blocked by Republicans

This is absolutely not true. Democrats defined this legislation start to finish.
And Biden's Transportation Secretary even split town for vacation during the critical week. >

Democrats passed a bill to avert a strike that had a chance of getting through Congress.  They needed 10 Republicans senators to play ball.  There was a ~~five~~ seven day paid leave amendment that was filibustered by Republicans in the final moments of the negotiation.
Cut out those GOP senators and the deal would likely have been substantially more favorable to labor.
