Pros
There is no pressure at work. There are no challanges. You can refuse to do overtime. Job security unless you are a notorious sick leave taker. Student friendly environment. Great flexibility of working hours regarding to study.
Cons
Minial job. No challange. Incompetency of management from Shift to Store manager level. The management is a bunch of "yes men", they only do whatever their bosses tell them to do thus they do not try to attempt solving problems. For this reason ideas are often ignored. Positive discrimination towards a certain minority, religious group (Shift ratio is approx 5:1 where 1 is European including UK) despite there is not many people live from this religious group in this particular area. As a result there is no team spirit, no outside work activities to build one. Christmas parties are held in the stuff rest room, seriously!!! No career prospect within above team leader or department manager level, even when you have qualifications, You are better off applying from the outside. No tallent recognition, no encouragement to step up on the carrer lader. The appraisal is a joke the annual bonus is worth approx two days of work (£100). The pay rise has been approx 1% since Justin King reign (in comparison his starting bonus was £500.000 in shares). The only benefit provided by Sainsbury's is the 10% stuff discount (M&S it's 20%).
