Yes. I got some accommodations at work, and although they were worth having, I often felt guilty about them.
They largely exempted me from a particular kind of work that had been my biggest problem. It wasn't popular work with anybody. It was an add-on that had nothing to do with the work that most of us had joined the place to do. There weren't enough people to get the work done in a comfortable way. I'd never have done that work voluntarily, and I felt that the management's behaviour was shameful, but once exempted, I felt I was somehow letting down colleagues who still had the work to do. Other accommodations at work also helped to reduce my anxiety, but also made me feel rather excluded.
I felt capable of so much more. The place often put downward pressure on people's professional development anyway, but the disability angle was the icing on the cake. I felt like I'd been parked and left to rot.
It was an extremely irrational feeling. Being left-wing, I applaud anybody in a capitalist workplace who can sidestep the management's pressure to get more out of them for less. I don't resent people for being on benefits. But to be among a struggling group and not to muck in and help, and to be running at 10% of my full performance, that just didn't feel right either.
These days I have no accommodations, I neither work nor claim benefits, so I'm not sponging off anybody, but I still feel guilty about every day I get up late and not really doing anything with myself.
