Pros

Fast paced, flexible hours and friendly atmosphere . There is a lot of training via web ex so travel is reduced . I attribute my success to having been on many committees allowing my input to shape others in a positive way. There are seasoned coworkers who gladly help out and advice is just a call away to another plant.

Cons

You will feel overloaded at times mainly due to the staffing which is rigid. It's a fast pace environment during the 1st 16 days which means your vacations are after the 15th of the month.
