Pros
The only pro I can think of is the training that you receive. Although it can be hit and miss with some employees depending on what area you're working in and what role.
Cons
Prepare to be bombarded by KPIs and targets, you need to sell this with this, increase on this, 4 item link sale, Rewards for Life cards, magazines, samples, customer feedback cards is just a few of the things you have to remember. There's always a shortage of staff so be prepared if you're management to not have a lot of time off if any. You're never acknowledged for the work that you do and the time that you put in or rewarded for it. The area manager is always on your back asking why something hasn't been done, why you haven't met a certain target etc. Just all in all very stressful along with all the tests and training updates that you have to do in between.
