What I see,Mr.Silenus, in my organisation is that people are crazy for promotion. And if the boss-man, tells them to put in a few hours more,they'd gladly do it.
I am told that on the day the promotion is due, the wives wait for the men to get home,and if they turn up without having received the promotion letter then the wife won't allow the hubby to enter the house. He needs to sleep outside that night.
