After reading all the posts up to this point, guess the person I tend to agree with most is Richard. But no matter who YOU agree with, remember
this:
Most of us are self employed or doing "piece work" for others, that is, No Work, No Pay. If you are a salaried person with full benefits, this does not apply but if you stop making money as soon as you stop working, your MAIN concern should be your Safety.
If you step on something and get an infection and miss days or weeks of work, or if you mis-step or slip in your sock/stocking feet and break a foot, ankle or leg and miss days or weeks of work, You Make Nothing for being polite/politically correct.
I wear flat-bottomed, rubber soled shoes 95% of the time, and this is from years of experience. I have caught heels, slid on leather soles, etc. due to "nice" shoes because I wanted to look my best. When I realized that to do my job the Right Way, I had to look more at the structure than where I was stepping at every moment, I had to choose the footwear that would keep me safest.
My experience has been that if you tell your clients that they have to go somewhere else while you heal for the next 30 days, they will have no trouble finding someone else, and you may even have some difficulty getting them back.
No One's white carpeting is worth all of my business.
