Not only the dust, but what leaks out of packages and onto the floor and shelves is what scares me. I've got 24 years in and don't have any health problems, but smoking on top of our work would be foolish. When the sun shines into the truck, you can see the dust in the air, and when you move pieces on the top shelf, no telling what jumps out of those cracks and heads for your lungs. The cleanliness of the vehicles has been brought up many times, but nobody wants to do anything about it. Handing a gritty box to a woman in a clean dress, on her way out the door to an engagement, still makes me cringe; especially when she's wearing white. The Fed Ex packages are much cleaner than ours, and that has to register with the customer; I've certainly noticed it.
