Yup, number of managers who say "I don't care about effort only output" is much higher than managers who actually care about output over effort.

I'm fortunate that my manager actually does act how he talks. Personally, I don't care too much if you value the presence of my butt in my seat more than how much I get done; it's your dime, so to speak. However if you lie to me about what you are paying me for, then neither one of us is going to be happy.
