have a pair of baggy pants dangling out of a concrete mixer and scream,
"Ohh no, wheres jimmie?!?!?!"

seriously, I would consider it a danger, running a power auger with baggy pants seems against common sense.
I'd lay down the law myself.... fix it or fire em.

I don't want to see it go back to the "Plum Smugglers" we wore in the eighties, but the back pockets behind the knee joint look has got to go. The worst thing is that they have to stagger around with their feet apart to keep the pants from coming down. That keeps work from getting done.

The good news is it is a safety issue, so you can implement a dress code without fear of law suits - successful lawsuits, that is.

Oregon has Hispanics doing most of their labor. It is the nursery state! Pay well or do it yourself.

You could by them all pants and belts or how about overalls? Yes it's a safety factor and I feel a company policy that needs being made so that it's clear as nails in their coffin as to how one can be fired for the 'bussin the sag'!

That reminds me of Jeff Foxworthy's joke ...
"If you see a poster that says 'Say No to Crack,' and it reminds you to pull up your pants... you might be a redneck."

I'd make the neat-pants-w/belt a part of company policy, as in dress code. Just as we'd tell an employing that there's no alcohol-drinking on the job, it's just as important to have a neat appearance - hair, shirt, hygiene and pants. Shirts tucked in, too.

Apart from practical concerns like safety Gangsta look is incompatible with good company image. It's teen rebellion style, whole point of which is to distance oneself from establishment.

The look is to express a desire to "stick it to the man". Like in the commercial, you are the man.

The main thing is how many clients are The Man or think they are. A friend didn't appreciate cement workers throwing their cigarette butts in her cement. It didn't hurt the slab, of course, it was the ATTITUDE conveyed that was offensive to her.

Simply have a meeting with everyone and tell them of the new company policy. pass out the papers so they all understand and have them sigh it. Anything else that needs to be brought to there attention needs to be written down and signed on the same sheet. If working conditions are favorable and people like their jobs they will adjust them selfs to the new company standards, or take a hike!

Hike your pants or take a hike?
