Actually, upon reflection, I decided to remind people of the model used by the Watchtower Printing Corporation: they never encourage anyone, unless you think "bullying" = "ecouraging". Nothing one does is ever good enough. The good one does is never celebrated and acknowledged. The bad is attacked like a pack of wolves on a lame rabbit. People are always being put down by gangs of other people.
Of course we all know that I've just described the "real world" as a few in here have intimated. What a healthy mental environment it is.
So, rip the shit out of everyone, and do it all the time for no other reason than to just do it so you will "help" them be "well-adjusted."
On the other hand,
a good manager has learned that yes: you can knock people around once-in-a while and yes: that can be effective when done as absolutely needed, but ONLY if you also gently take that person by the arms and lift them up and give them lots of acknowledgement and praise when it is warranted, too. It's a delicate balancing act, but some managers are good at it and their people are absolutely loyal to them, respect them and even love them for it.
Short version? Morale does not improve when the beatings are increased.
