Good if you are out of other options and desperately in need of any employment
Pros
You get paid on time.
Cons
If you are an efficient and hardworking person, instead of being appreciated or promoted, more likely you will be taken advantage of and made work over your limits. Multiskilling has another meaning here - not only you have to be able to work in different roles but also do it simultaneously - be in different places, do different things - at one time of course. Unachievable targets, huge pressure has led many Tesco's employees to hospital (due to physical and mental disorders). There have been even suicidal attempts. You work as five but you earn as one. On the other hand, if you have some relatives or friends working as managers in the same store, you will probably have 8 or less ;) hours a day of peaceful work. You may also spend your time on coffees and smokes - others will do your job at "voluntary" non paid overtime. You will be given prospects on promotion (regardless your performance) as well - but only if you are somebody's protege, because back-scratching is prominent in this company.
