Seek help to get your employees tested for covid-19. Start work. You can still get infected after the tests. The test itself can provide a false negative. So, disinfect the work place, wear a mask, use a mouth wash, suck on lozenges, wash your hands the first thing at work and, if your are sick leave the work place and see a doctor.
The cost of a test kit varies, but even if it is over USD 100 it is still worthwhile. To passively wait out the disease for months no-end, is even more expensive.
I am still brain dead.
