Frustrated with Boss's Response to Request for Fewer Hours

Thank you everyone for the support and advice! I think if she does try to schedule me for a long day too many days in a row again I will bring up the ADA to remind her. She said she didn't realize she had scheduled me for 7 days in a row and that makes me nervous as to what kind of manager she is 😕

Yes bring up ADA and get a medical note/records ready if need be. It’s reasonable so they can’t just say no.

Definitely contact HR if that's a possibility! Maybe a doctors note too. Like the other commenter said, this could easily become an accessibility and discrimination issue under the ADA in the US, and I know the uk and some other countries have similar laws
