I can't do this anymore

Does your phone have a voice note recording feature? You should turn it on before any meeting you have with HR or your boss, and slip the phone into your pocket out of sight.

Ohio has a one party consent law, which means that you can record any damn thing you want as long as you are a party to the conversation. You're consenting, and that's all you need. Your phone's memory will eventually fill up, so you need to figure out how to back up those voice notes off your phone and then delete them from the phone to free up space.
