Pros
Salary & benefits. Intelligent (albeit sheepish) coworkers. Some good managers/supervisors (the good ones don't last very long...)
Cons
If you're a member of the club - 2.5 kids (or aspiring to get there), married, pseudo-intellectual, conformist - you will do fabulously. If you let the job be a job, resign yourself to collecting a paycheck without hope of advancement, and never let anything upset your health or life, you'll do just fine. There are unseen power brokers here...certain people can get away with murder while others have their HR files polluted over the most trivial of offenses. There's a constant fear of being fired and a constant drive toward the annual bonus (which is an exceptional sum). However, that feeds a predatory culture where, instead of providing support and flexibility when life happens, these unfortunates are subjected to death by 1000 HR paper cuts and, ultimately, shown the door. They are also ostracized by their peers...who wants to associate with the blacklisted in a culture of fear? Quite sad, really. I've seen a lot of good people be let go in unkind ways.
