You are supposed to get paid by Target for jury duty.
@HLN13 ask for HR help. Someone may notice you put it on the board so calling out is an option but maybe not the best move for someone hoping to promote such as yourself. It's obviously best if the store can find someone for you and most will respect you are letting them know.
I would say "hey I don't want to call out the day of and screw everyone over, can you guys help me get this shift covered?"
A lot of times it's a matter of asking non hardlines people who leadership would feel comfortable working a shift there like a young energetic cashier.
Last thought: We've also had situations where we need to cut payroll and we allow you to cut your shift. A mid hardlines shift while important is not absolutely crucial like a closing hardlines shift
