A further thought.
Longshoremen, unlike rail workers, are covered by the Taft Hartley Act. This means Joe could order them back to work for eighty days.
Joe is POTUS46 for another 122 days, which gives him "room", as a lame duck, to try and reach a collectively bargained agreement, but if the "health and safety" appears endangered (don't ask me what that means, but it is language within the TH), he could impose the back to work "cooling off". TH definitely gives the government more sway to end a labor dispute than does the Railway Labor Act.
But Joe is pro-Union, and he as such would be reluctant to use those powers.
The outcome of the Election could definitely be a factor in what action, if any, the government takes to resolve the matter. But "let's not go there", as such would be "talking politics" on a matter not directly concerning the railroad industry and in violation of the guidelines promulgated by the site Administrators.
