I think despite Lowe's attempting to tell us we're all low to now risk for contacting this disease (what a laugh!) and using a lot of intimidating language, the policy is actually very lax when you steps back a few feet:
To use it you can use a doctor saying they advise you quarantine at home for two weeks. You might think this is hard since wouldn't you need to test positive for your doctor to recommend that? Uh, no. In places like California or Pennsylvania, everyone is already being advised to stay home for two weeks. So not exactly a stretch that regardless of your job your doctor would advise you to follow suit and stay home.
More hoops to jump through than at Depot, and that says a lot about the character of the higher ups at Lowe's, but it should be easy enough to totally sidestep their paper tiger.
