It doesn't have to be a fight. If you want to work remotely, apply for remote jobs at remote companies. There is no need to negotiate or bargain or convince anyone of anything.
With a third of your life spent at work (at least, but hopefully less), this is no way to go through life. Everything is up for negotiation.
People who want to attempt to unionize to get the right to work remote can do so, as organizing is federally protected activity in the US and it only takes 30% of employees of a bargaining unit to petition the NLRB to hold a union vote: https://www.nlrb.gov/about-nlrb/what-we-do/conduct-elections
This is a labor rights issue, plain and simple. It makes little sense to be subjugated to management edict “because they say so” when there are labor tools available.
