On the flip side I had a manager who had written a lot of the codebase before I joined and had a terrible time allowing anyone to touch his precious baby, regardless of how much his prior βartβ was hurting us, our productivity, and by extension the company.
Yeah... I said it was a "flaming pos" I felt bad about that. But he won't let me add tests so idk whatever. (we prototype software so speed is the main goal but yeah, stuff starts breaking, backtracking, hey... tests)
This is so important, my managers who didn't code pretended things weren't too bad and took a "just deal with it" attitude whenever I proposed going for a QoL improvement.
