It is changed around depending on your arrangements with a manager. It is shift work
I work 9am-5.30pm every Monday to Friday.
Other people work shift work so will not be working the full 9am-8pm.
The full days are more to be expected as people leave all the time without a quick turn around of rehiring people so we are usually short staffed.
Yes shifts change
Hours vary and they are very flexible and fair when it comes to working weekends/evenings
