I've finished training for a new company and noticed my line manager has been micromanaging the hell out of my daily functions. She's been giving me shit for changing my chat messenger status to do not disturb when completing grueling tasks; I don't find this as an issue and keep getting threatened with warnings. When I actually have a question regarding my work she doesn't respond and I'm forced to wing it, which, causes even more issues. I've already begun looking for a new job but in the meanwhile what is the best course of action?
