My company supplies us with uniforms that they expect us to wear. I agree with that policy. We have a lot of our techs that wear shorts and scruffy t-shirts. If I were in charge, they could go home and change. Image is a lot when you are the first and possibly only person the customer sees. In the span of a day, I have gone from an Ice Cream storage freezer (-40 degrees) to a plant that uses steam in their production facility. I carry a freezer suit with me all year round. But I still wont wear shorts on the job. When I go home, I can wear what I want.
