Your company must make huge profits if they're paying you 20% higher than other companies would pay. If I was you I would have to change my job and my lifestyle in order to be happy. I'd find a new job and a new place to live. I worked for the Military as a civilian for several years and I could not put up with the arrogance, ignorance, lying, passing the buck, personal attacks by co-employees/supervisors, etc. so I quit, sold my house and filed bankruptcy. Constructive criticism didn't exist where I worked (and doesn't exist in most organizations). Can't say I make a good living now but at least I'm not around those game-players and psychos anymore.

Hard to believe all of the slacking that goes on in your workplace. I worked as a temp for a few days at Verizon and I could not believe what was going on in the office - women walking around in slippers, playing solitaire on their computers, etc.
