I work for an insurance company and every all employee meeting we hear about the desire to fight systematic oppression, what we are doing to combat that, and how we can promote diversity. The CEO even worried about how we don't have a good diversity of thought and how we need to make people more comfortable being themselves. But throughout the whole meeting it's heavily implied that conservative voices aren't wanted. He even made a comment that implied trump is a joke. Not to mention we won't go back to the office until 2021. Just needed to vent where people will get me.
Edit: just made it a bit more vague so i don't accidently dox myself. I trust you guys, but i'd rather be careful.
I'd say if you get any indication the blow is coming, recording the meetings you attend. Just turn your phone on audio-record and leave it running without the screen on. Don't tell anyone.
This may be questionably legal but it has some merit. If what they do is questionably legal, it's useful as a deterrent. They would have to fire you for a legitimate reason, which they would then have to concoct.
At the very least, if you get called in for a "review" of any type, ABSOLUTELY record. That saved at least one person I know in academia when they turned what was supposed to be a routine pleasant review into raking her over the coals and near attacks on her.
