so i was scheduled on a day that i am unavailable talked to my etl and said it was up to me to find someone to swap or take that shift for me or i am held responsible. i also have tickets to go see styx and reo speedwagon with my dad didn't bother to request it since im supposed to be unavailable that day. what should i do here? im a FOSA and only one other person is trained for it at my store so if he can't then my only choices would be to miss the concert or just call out.
