Vantaggi
A great place to get in at the crack of 10, take a two hour lunch, and be done by 4. So very easy to retire on the job if you kiss the right a@@es. The executives have really, really nice exotic sports cars and they're cool to look at in the reserved parking spots right next to the building entrances, but they make sure you'll never be able to afford one. Ever.
Svantaggi
Where do I begin? Bad pay, bad management, no opportunity for advancement (unless you are politically astute, but even that often backfires). If you don't have a technical degree, you are scum and treated as such. Way too many people doing the same thing you are doing. Enough deadwood to heat Siberia for years. Fiefdoms and territories that are defended with nuclear devices. Management just plain, flat out, utterly, completely does not give a s**t about you. Until it's time to lay you off. Then they're glad you're around so they have someone to chop.
