Pros
It was a good place to get work experience for those who are just starting out. Better pay than fast food, and insurance was pretty good. Almost always busy doing something. Opportunity to move up if the right people like you.
Cons
High turnover rate because management didn't appreciate hard workers. They pile tons of extra work on the hard workers as "reward" and expect you do make no mistakes. Don't even raise the pay when you are handling the workload of 2+ people. They also liked to play favorites. If you were well-liked or were known to make a scene when disciplined then the rules didn't apply to you, but if you are quiet, do your job well, and mind your own business you will be wrote up the first time you don't follow the rules exactly. It was also chaotic. If the company had a new job come in, they told you the basics and left you to figure it out on your own. This normally wouldn't be a big deal, but in call center type work, where the customer service is the most important thing, it makes it very hard for the customer to believe you know what you are doing and come out with the desired results.
