The bindery boss who micromanages each stitch needs to back off

I've been a bookbinder for ten years, and my current boss is the worst. He watches each move I make, from getting the signatures ready to sewing them. It makes me feel like I can't breathe, and my hands shake when he's near. Just yesterday, he changed my paper grain alignment in front of the whole shop. This pressure kills the fun of making a nice book. We're artists, not factory hands. If he doesn't chill, I'm leaving. Good people will go if we're not treated right.
