Walmart Supercentre Vision Centre

I use to shop at walmart weekly to say the least, however after hearing from employees and after seeing first hand how the “managers” seem to treat their employees and even some customers is sad. It seems as though the management at Walmart in the sault greatly abuses their powers. I have personally watched different managers talking very unprofessionally with various employees. I have heard many situations of very wrongful dismissal simply because a manager didn’t like them. Need new management
