Working Hard...But Not Working Smart

A friend sent this regarding working hours

I also know through one of my contacts that they didn't give it to the other
manager who left awhile back.  I know these guys work long hours.  I just don't
understand these tech companies, everyone seems to be working 80 hour
weeks.  I don't know where they get all the work?

He's a  nice guy  but works
too much - creates alot of it himself.  They are doing an efficiency study
trying to convince people that they need to hire more folks, which they may
or may not. But he said the study has said that he has averaged over 15
hours a day this year (includes weekends).    Again - I don't know what they are doing.

I'm going to do post on working hard but just realized the Ryder Cup is on.  More later.
