Is it wrong to go to the head manager about your area manager if he's really a bit of a bully??

@TwiddlerofThumbs an example being..customer service...I was dealing with a customer..took them to the product they were looking for, and done everything expected with a smile..whilst talking to the customer..he came by and asked me what I'm doing. With a look of disgust on his face..I said just helping a customer..he then said I need to move quicker or start another task. Which would be avoiding customer service..but I helped her..then in my review he gave me a red warning for customer service..said I don't look confident or am shy..before starting at this store I worked during the day behind a till and on the floor dealing with customers constantly..if anything starting in this bigger store I have as much confidence as I need..but he threatens my confidence..says my customer service is poor..the customer isn't my problem..the staff isn't.. the store isn't...he is my problem..and he gets in the way with multiple things

@All2livefor Bosses sure can be fun, especially in retail. And from what you have stated, sounds as though your boss doesn't like you or is likely completely incompetent and needs to make it look like hes on top of things by finding imaginary problems.
You could go to his boss, or another manager in the store and explain the situation and see if they have advice for you in how to deal with this particular person.

@TwiddlerofThumbs and one more..he came by me saying..to stop congestion..you should only have to cages on the floor..back stock cage and a cage I'm working from..I told him..I've only got two...he pointed at one and asked what's that then??..I said "my back stock cage"..he pointed at one up the other end..and asked what's that up there..and I said..that doesn't belong to me that's John's cage from the section across from me..and he said "okaay in a quiet tone and walked away...but didn't pull up john who is older and there longer than him..even though he had five cages on the floor which is against the rules..picked on me..doing everything right xx

@All2livefor Also, if you have not you need to ask him what he feels you should be doing to improve your customer service skills. In fact, when he corrects you in any way ask him to explain himself, what he expects and what you are doing differently than what he expects. Now, it wont be reasonable in every situation, but don;t let him intimidate you. That is likely his goal. Hes going to manage you out of a job is he can. Which is often just bullying and intimating an employee that wont stand up to them in a reasonable manner and confront them when they make accusations about your work.

And yes, it's because he was looking to pick on you - not John, who knows the rules and does his job in whatever manner it takes to get it done.
