Vantaggi
Can't think of any. Complete nightmare. At first, the pay seems decent, but you soon realise for the hours you put in, it's not great.
Svantaggi
Too many too list. I was on the Graduate Trainee Program, and in effect you are nothing but a glorified shop assistant. No investment by management into developing your skills as a leader or developing you as a person. Unrealistic targets; write offs, productivity etc. Non food items that don't sell and clog up the warehouse. Unsociable hours. Staff that ring in sick, that leave you as keyholder responsible for their shift - lack of staff on the books often mean you have to personally cover this if no one else that can lock up is willing to work. No overtime pay, long weekly hours. Area Managers that don't have a clue.
