My understanding is that they must offer a reasonable accommodation. For on call, I imagine that takes usually just takes the form of assigning some different responsibilities. Doesn’t seem too burdensome. I worked with someone who had a sleep disorder. She would do twice as many on call shifts but only from like 8am to 8pm during the day. Someone else would take the night shift component, although that usually rotated too. It wasn’t a bad trade because most of the on call work happened during the day. The night shifter only rarely got woken up to deal with something, so on the whole they dealt with less on call.
