I don't know anything about the dept of rehabilitation but I have been declared disabled by social security since I was 21. I am 33 now. I haven't ever had to call in depressed, but I have had to ask for extra time to get tasks done, especially at my last job, which was a large home improvement store. Large amounts of people can get to me, as well as a lot of noise. As far as I know, at least in my situation, they have to give reasonable accommodation for the condition by law (ADA if you want to try to read it).

One main issue I had there was one day they were testing the fire alarm. 4 times during my shift. I had to step outside each time. I explained the situation to my dept head, and while annoyed, she didn't say no.

Idk if that helps, but that's what I know.
