Petro Canada review: Managers behaviour towards employees

I'm very frustrated with the manager. Her name is Nazwa. She's the manager of Petro Canada 2295, Division Road, Windsor, ON. She's horrible. It is affecting my mental health. She always keeps shouting without any reason. She behaves really rude. The customers also observe how she behave. Please help and do something about it. She behaves really bad. She keeps shouting. She is very toxic. She forces people to come for work even if they don't have shifts on that specific day.
