Pros
You can work in your pj's and you don't have to spend gas money or time commuting. That's about it!
Cons
You will earn minimum wage, won't have holidays off and there are no paid sick days either. Vacation time is also unpaid (and yet it is restricted to 2 weeks a year and subject to their approval), and just as described by many other employees, you can count on your managers being disrespectful. Basically, they will give you only what they are forced to give you by state law, and nothing else. Chances are you will not have an opportunity to move up, either. You will never be informed when a position opens, and you can only start receiving benefits at the management level. In other words, you will do all the work for minimum wage, and those who sit in an office listening to you and critiquing your calls will get the benefits you're not entitled to.
