How to manage

I'm not sure beimg able to rant like Heather Mills is a sign of a good manager, but the common cry from Wrexham for someone to get stuck into the team's an interesting one. The question to ask's how would you react to a good rollocking at work? Would being screamed at double your productivity or demotivate you? If you work in an office would you really bust a gut if the boss abused you, or just feel a bit less guilty about the time you spend surfing the net when he's not looking? Likewise, if you work in a fast food joint a carpetting is surely more likely to make you spit in the burgers isn't it? I'm not saying motivation doesn't exist, or that it can be achieved only by the carrot, not the stick. However, both Arsene Wenger and Rafa Benitez seem to have won plenty without resorting to the hairdryer, though Wenger's occasional explosions are said to be spectacularly effective!
