Pros
You get to work by yourself & not be bothered by anyone, listen to ipod/audiobooks, vacation/personal/sick pay after 6 months, wear "normal" clothes, and get health/dental/eye benefits.
Cons
Not enough pay/horrible raises, there's a ridiculous "point system" for being absent and being late (even if you have a doctors note or emergency room note they don't care), in AM shift they watch over you like a hawk, you get judged on something called "uptime" which is how much time you spend away from the computer (this includes going to the bathroom.) You only get 30 minutes so if you are feeling sick, having bladder problems, stomach problems, cramps .. you're screwed. They don't care if you have a good excuse for needing to use the bathroom more often than others.
