Who knows when we may also find ourselves in difficult employment conditions - I hope not.
But, to add my ha'porth, if you are shareholders perhaps a mass presence at the AGM or tabling questions, or even calling for a SGM/EGM might concentrate minds without financially ruining everyone.
If not shareholders, or anway, if there have been material changes to terms and conditions since you started working for a company and there has been no attempt by your line management to explain/justify/ask for cooperation this may be leading towards constructive dismissal, even if you resign ?
In my experience, fieldworkers always get dumped on (out of sight and out of mind) even when they get to spend time in the office (not many of us want to do that). Does anyone talk to line management, and get replies ?
Good luck
