Terrible management - Customer Service Associate ASDA Employee Review

I was on my shift last night, went to the toilet & say down to poo, I looked up & there was the duty manager looking down on me. When I questioned him he made up 2 reasons why he needed to be there, then tried to physically intimidate me by standing in my way & not letting me pass, then told me I could make a complaint but it would go nowhere. I have reported the incident to the police. You need this job to help pay my way through University but my advice to anyone would be do not work here. Store management are bullies & speak to you very badly pretty much all the time.
