I noticed you said the PA had another job on Sundays and ignored that because his other job has nothing to do with Target. He can have another job or he can have to baby sit or he can just want to sleep in late after playing pool until 5am. All of those hold equal weight when someone is not available to work, it does not matter the reason. The ETL is salary, looks like he better take his lazy ass in for those 2 hours and cover it then. The whole thing about asking for time off 2 weeks in advance works both ways, once it's posted that's what the schedule is. Perhaps you can work late that day and cover until 5:30!
