Pros
If sales go well, you can (occasionally) make a bonus obtainable. Also some staff discounts are quite good (discounted price plans on contracts etc). Some stores can offer flexible hours (although new staff are now only given temporary contracts).
Cons
The culture upto a few years ago made it hard work but rewarding. In recent years though, bullying is becoming commonplace from management as targets are increased year on year (and the value attached to achieved sales diminishes). We have an obsession within the business of pushing insurance products onto all customers with high targets to achieve on such sales. If a consultant doesn't meet these, they are then managed out of the business. Overall the working environment is now quite toxic and I'm glad I'm leaving what's fast become a sinking ship.
