In the end, your mental and physical health should always come before the job. Money isn’t that nice if you are stressed wreck. You should still look for other work just so you at least have some options if it ever gets too awful dealing with all the bullshit your current work forces on you. It’s probably not going to get much better and any solution regarding disabling/mitigating the current surveillance is likely temporary at best.

Just try to do it in such way your current employer doesn’t know about it, just in case they get uppity about it. So use only devices managed by yourself for it and dont talk about it with others working for same employer.
