Give em a shot and get them back to work.
got a friend that runs a business he's requiring his employee to get vaccine otherwise they can't work. he told me some of them said no so he fired them on the spot. some of them wanted to keep wearing diaper on their face but he told them it's bad for image of the business. so some of them got fire some of them got vaccinated which i guess for the customers is good thing so they dont have to worrying about catching covid.
