I have documentation. They don't care. HR said to just work with my manager on accommodations. My main problem is dealing with ambiguity and context switching. That's something they can't change given their chosen work model.
The old model of working was that you supported 1 main app and maybe a smaller 1 or 2 that were related. These were usually in 1 stack and well documented. The new model is that teams are typical supporting 6-10 apps in multiple stacks. I'm slow when switching between apps and stacks, and without consistent exposure to a single app/stack, I won't get faster.
It's funny though - they talk a big game and even hire in Auticon contractors, but then refuse to do anything for existing employees. I assume a least some of those contractors have similar difficulties as me.
