Third (3/3) time they denied by availability change.

The first 2 I get I was a seasonal TM within my 90 days- that’s over now. If I say I’m not available I’m not available. The only day I said I needed off 100% is Sunday and I trimmed my hours to 10-11 instead of 6-12; but we open at 8 and close at 10 now that Christmas is over. I’m kinda pissed. They know I’m a primary caregiver for a family member yet they still do this.

Advice? Or am I being unreasonable? Edit: sorry if I came off as an asshole in the comments im really irritated but it’s not y’all’s fault.
