What is the procedure of going to inspect a building with employees that are unaware of individuals whom have the diagnosis of COVID-19 currently and no one seems to care about the other employees health and well being?

It is from my understanding that if an employee has been diagnosed with any communicable illness, the staff must phone everyone they have come in contact with and ask that they monitor their bodies for symptoms. If one should have symptoms then, the individual must go to the nearest testing site, await results, and follow universal protocols and precautions.

My understanding...they have an area outside that test for Covid. And they have standard procedures that they must take to make sure their staff and individuals who were exposed to Covid be taken care of and notified immediately.
