5. You Think You Might Be One of the Bad Guys
Morality is a complicated thing in the modern world. Companies own companies that their employees don't even know exist. After a couple years in the workforce, you realize that 30Rock's joke about the Sheinhardt Wig Company owning NBC isn't too far fetched. This means that even if you are just a pencil pusher or a mail room boy, your company might be complicit in some messed-up business dealings. How many times have you heard the story of the environmental lawyer who goes to work for an oil company, a principled artist who makes derivative schlock, or a non-profit warrior who is lured away to with a big paycheck from a huge corporation. Sometimes, you have to do things just for a paycheck, but there are also times when you have to stand up for what you believe in and protect your soul. If you wouldn't feel comfortable telling your friends and family what your company is really up to, then it might be time to seek more righteous, if a little less lucrative, pastures.
