My team just changed managers last week. He's started out being very micromanagey - he'll constantly call us to see what we did with the previous 15 minutes and then say that we need to change tasks and work on something else for the next 10 minutes, and also try to work on writing some other document in the 30 seconds that we're waiting for a Teams response from someone, and also he needs to observe us drafting emails, and then he picks apart our word choice and asks why we believe it's professional to make typos while we're drafting (not sending) emails. He wants time estimates for things like responding to an email or scheduling a Teams meeting. He's constantly joining code review or pair programming meetings that he wasn't invited to and spending the whole time criticizing someone's IDE font size or indentation settings.
I'm concerned about this because micromanagement is always what's caused me to have to find a new job so far. I have a really hard time dealing with this. If this was an equal power interaction, I'd tell him to stop bothering me, but since he has all the power over my health insurance, I can't do that. Is there a tactful way to stop him from micromanaging, or is it just time to find a new job?
