I talked to a junior domo guy at Meijer (midwest grocery chain) he seemed to think most of the problem was in transport. Not sure if he’s right, but that was his view.
Half the country is standing in line to take a Covid test, or they've cleaned out all that at-home tests and if you have the sniffles, you're going to test positive for Omicron. This means for many, a mandatory 5-10 days off of work.
I'm in the same boat right now. Forced to test by my employer because my son tested positive on Friday. I had mild cold symptoms over the weekend and tested positive myself. I can't return to work until the 18th even though I now feel perfectly fine.
