The CDC hasn't had this guidance for almost a year. So it sounds like your DH workplace is either not up to date on guidance or are being very cautious for some reason (maybe they don't want to be hit with workman's comp claims).
I think it’s because the employees complained so much but its a huge corp so I’m sure there are other reasons.
I’m hoping his company will change its policy since the CDC has updated its guidelines once again. They are so far behind at this point something has to change.
