I used to run one of two crews for a general contractor (an engineer)
I had between 6 and 10 folks working under me at any one time, and it was understood that any time you felt you were working harder than me, we would trade jobs for the day. (No one ever took me up on the offer).
In at least 10 years there, i had to only fire one guy. I caught him breaking the law and our contract, by polluting someone else's property, instead of hauling away the debris as we were under contract to do.
I gave him a choice, clean it back up, and do the job correctly, or I would mail him his final check, misus the cleanup costs.
He chose fist fight on jobsite. (That's a major no-no).
I drug the fool off the property, after a lesson in manners, and mailed what was left of his check.
Since i cleaned up his mess, he paid me to give him an "invitation to the world".
No regrets.

An unemployed Jester, is nobody's Fool.

the only real difference between a good tracker and a bad tracker, is observation. all the same data is present for both. The rest, is understanding what you're seeing.
