Where did you read Frederick Taylor say "More hours are better"? He advocated getting the most done in the shortest time possible actually. This goes against what he preached.
+1 for that. I think if more people read Taylor and fewer read, say, Jack Welch, then work would be a happier place. Because implicit in Taylor is that you need to create the conditions that let your people get the most done in the shortest time possible. That does NOT mean "tyrannical PHB cracking the whip". The existence of a PHB in an organisation is a declaration that HIS boss hasn't taken Taylor (or the boss' own self-interest) sufficiently to heart.
