I used to work, in the UK, for a big American company. Every 5 minutes a Senior Vice President would be stabbed in the back and his successor would be obliged to do a World Tour, taking in the UK.
Prior to the arrival of this person he would always be described as a "Nice Guy" and, of course, we were encouraged to address him by his Christian name as in: "Tod's the new VP of baby killing/pussy cat strangling/widow smothering - he's a really nice guy!" When Tod finally arrived he was just as big an arse-hole as the rest of them, and could probably have given Genghis ("he's a really nice guy!")Khan lessons in human head pyramid building.

Other management cliches that I detest are: 'proactive', 'team-work' and 'new-ways-of-working'. The latter means: "throw out everything that works and replace it with bullshit".
