It can be extremely rewarding. If you have a passion for photography this is a great place to start.
Cons
Your satisfaction will depend greatly on the specific people you work with and for. When I first started there it was with a very positive staff environment and I always left with a smile. Changes in staff and management have made it a nightmare. It is imperative that you have a passion for this job, because if you don't it is not worth it. If you are lucky your managers will be positive and encouraging and will appreciate you. But you may end up with the opposite.
