Time to start looking for the next gig. That boss is unsuitable for management. Lacking emotional intelligence, willingness to mentor, and so forth.
I've never successfully managed upwards, never have been able to turn situations like yours around. I've had jobs that I really liked, so tried really hard to make things work.
It was never worthwhile. I always regretted the effort.
The good bosses I've had made all the difference. And why I happily stayed in gigs, despite other offers, despite red hot job markets, despite more interesting work.
Life's too short. Don't stress the losers any longer than it takes to get away.
