Variety of reasons, burnout, management style changing or expectations changing in a way that I can't keep up, I guess those are the usual ones and they're closely related. Most companies also just arbitrarily pick 2 week agile sprints with daily stand-ups, often increasing the amount of meetings as time goes on, and this is usually where things start going downward for me. There also tends to be a decrease in autonomy to get my work done over time, which helps me feel like shit on a daily basis, and so it starts a negative spiral.
In one case I was doing reasonably well with my software dev tasks for a while, but then they assigned me to periodic customer support, and I said up front that's not something I'll be good at. At the same time, my manager tried to increase the oversight of my work, because I was getting slower at it. So I'd wake up every waiting for my manager to "check-in" on me like a child, eventually getting to the point where I couldn't bring myself to get anything done and just resented my existence.
I'm in an ok spot now, for now, but who's to say how it'll be by January. All I want is a place I can do good work for, for a reasonable salary, but it's been very difficult to find.
Damn, I’ve been there — at least in the situation where the manager concludes that micromanaging will somehow make the managee more effective, rather than in the very best case, hamstring it by bottlenecking on them and in the average case, deeply humiliate by trying to make the managee do things exactly the way they would (but be worse at it, because the managee is not them and could have their own different, personalized, effective work style).
Yes, it's both. Thankfully I'm in a completely different timezone, so have reasonable grounds to not be in every meeting or available between specific big blocks of time. I have no interest though in trying to reduce my own motivation toward the work, so I simply said more this amount of meetings will reduce my productivity. I'm ok with how things are, but anything additional will displace other work from my day.
