Pros
Good support from management on issues with employees. Very straightforward and honest reviews. Management is also almost ALWAYS available when you need to talk to them. The pay is good compared to similar jobs. The job is very structured, so you're never wondering what you should be doing. There are quite a few programs in place to show the employees they are appreciated, both by management and other employees. For the most part, they are pretty good about weeding out the people who create more work for others.
Cons
Once you get to a supervisor position, you are expected to bring a much higher level of quality to your work, this can be burdensome to people unfamiliar with the job requirements. Also, the hours get to be a little ridiculous. You go home when all the work is done, not when your shift ends. Sometimes you do not get the training for your job in a timely fashion, class schedules are set in stone. Management can be abrasive in their straightforward demeanor.
