As an employee of one of Virginia's largest manufacturing companies, the practices and protocols dictated in the standard neither lessened or increased the number of COVID cases.  It was a failure as far as protection goes and was never based upon science but upon political knee jerk reactions.  

As a member of the COVID committee and tracking team, over 97% of the infections originated from outside the facility within family circles and other sources.  Instead of seeing a decrease or flattening of the curve, we saw increases in health issues associated with wearing a mask for hours on end, as well as increases in anxiety and stress associated with angst created by the needless regulations.

Where OSHA has been a great help in reducing job related risks in most areas, this one was a dictatorial decree over an issue that was not intended to be governed by nor considered a true function of OSHA.
