Glenn Reynolds has a great management article in TCS Daily about companies blocking internet use at work
"Well-run companies look at outputs -- how well people are doing their jobs -- rather than simply trying to make sure that employees look busy. And given that U.S. economic performance over the past few years, as Internet usage has boomed, has been excellent, it's hard to believe that this websurfing is really threatening productivity. Instead, I suspect, it's threatening management's sense of control. (After all, if they really cared about people wasting their time with computer technology, they'd ban PowerPoint, not Web-surfing.)Amen ... and he shows a healthy disrespect for "managers"
Ultimately, this issue isn't about employees but about management. Managers tend to resist output measures because output measures require managers to take uncomfortable action: They have to tell the good employees that they're doing a good job (which tends to encourage the good employees to want more money) and they have to tell the bad employees that they're doing a bad job (which tends to make them resentful and unpleasant). Nonetheless, I think that measuring the work done, rather than just whether employees manage to look busy, is going to be the management trend of the future. Success in business, after all, usually has little to do with whether managers are comfortable or not."He sounds just like Jack Welch
"I never associate passion with the word manager, and I've never seen a leader without it."
