Vantaggi
I have been lucky with colleagues, worked with mostly good people. Never get bored at work, time goes quickly, keep a pedometer (I have had 30k steps on a shift)! Keeps you fit. Very varied tasks.
Svantaggi
Plenty of cons too many to list. Close shifts often go past scheduled time. Long hours for managers, 50 a week. Constant pressure from above to perform better and faster. Always told where you went wrong, never praised. Rotas changed at short notice. No extra pay for store assistants on Sundays/bank holidays. Never enough staff in store leads to the most common complaint - long till queues. Managers expected to go well beyond call of duty, contacted out of work often and any time of day. Four years in the company I only ever worked with one district manager (DM) who was pleasant to staff. I won't go on. If you can work had and fast (I managed it) then you will survive and the money is quite good for management. But you will member get any long term job satisfaction working here.
