From one of our road drivers on bullies...

ALWAYS had a problem with bullies,
My way has always been to drag them away from everyone and confront them in private. I try to reason with them and if that does not work,
I escort them from the property...Find someone else to finish the job. A few times it's been rough, never had to call the law.
That's why I've been building crews-EVERYWHERE.

The guys I have are all background checked-AND, more important, CHECKED BY ME!

....If you find good labor or you have good employees or co-workers- treat them right.
It will come back to help YOU and remember- respect and thank you.

Get the bully or the uncooperative away from the job and others, they will only pollute the situation and be cancerous.
