Is there a summary explanation?

Republicans got rolled… again.

[Red Badger]

You know, the bill evil Republicans voted against … is what the workers actually rejected. But Democrats, along with the media and their Lefty Twitter trolls, are framing this as BIG MEAN REPUBLICANS don’t want rail workers to have sick time. Of course, they are.

[Don Corleone]

All totally political and unnecessary because there is a 90 day ‘cooling off”period in the RLA that should have been used so no holiday strike was even possible.

Republicans voted with the workers, and the Dems are lying about it.

[Tell It Right]

From the article (list of posts), here are IMHO the 3 most important facts:

1. Over half of the union members voted against it. (There are 12 unions involved and in a weird quirk of numbers, a majority of UNIONS voted yes, but not the unions with the largest number of members.) So calling it a "tentative agreement" is a lie when most members of one side didn't agree to it.

2. BIDEN’S REPRESENTATIVES HEARD THE ARGUMENTS REGARDING SICK LEAVE AND RULED THAT SICK LEAVE SHOULD NOT BE INCLUDED. This was in agreement with the rail worker’s management.

3. The House passed a bill to force workers to accept it anyway. This is what the Republicans voted against -- forcing the workers to accept what they rejected. The Dims are the ones trying to force the workers to accept the "agreement" without the off time policy the workers wanted.
