Of course they do!
Just like the bone-head RBC oversneer that I saw first hand on the last KH project I was at some five years ago. He came in, spouted off about "safety" and how we were showing loyalty to JAH by being obedient, and how anyone not following the safety rules would be barred from the site, all the while standing in front of the "Hard hats must be worn at all times" sign with his tucked firmly under his arm!
I guess the "rebel" in me came out because I took mine off, tossed it in the corner and said, "If you don't have to wear one, neither do I!"
I was "invited" to leave, which I did.
