Isn't it the case anyways in most retail situations that you need to be reachable as much as possible if you are a manager? The store is a team. You need to work together and that may mean working doubles, etc. on short notice so the store stays open. Sometimes you need to work when you don't want to. Sometimes you need to work when you are "having a bad day." Its part of working a retail job.
Isn't that pretty much what I just said.? If you know you need to be reachable then yes. I believe that the OP never said that it was known that you needed to be reachable until just a little while ago, this is why I posted what I did.
