promoting friends over high achievers, nepotism, gaming performance metrics, gaming peer-reviewing systems, deny profusely blame for things you did, framing others for your mistakes, withholding key information from peers, installing hidden scripts to break things when you are not at work, closing unresolved support issues to reset SLA metrics, clock-in to work then take a stroll through the office until lunch, clock-in to work from home and go watch Netflix, take sick days off to undergo cosmetic surgeries...

just some examples from the past couple years that came up real quick =)
