Pros
Large, well-known company (FedEx) combined with the, now obsolete, Kinko's name makes for a reputable shipping and printing company that is somewhat reliable to work for. You are never doing the same thing every day, especially in production. It can be a fun job that will teach you a variety of skills.
Cons
The people working in the FedEx Office stores are given instructions from people who have never worked at a store a day in their life, ie: Express, Ground, corporate, 1-800-Go-Fedex, etc. This makes for a VERY frustrating experience. You watch a lot of undeserving people get promoted, as is the downside to many retail & customer service positions. Every store is run differently, rules and procedures are changing constantly which lead to price differences, policy differences, and ultimately customer complaints. The variety of this job, while a pro, can also be a con. The upper management is an unfortunate joke in most cases, but again, that can be said for many retail & customer service jobs.
