Why is a checkout employee sick and coughing ? Why you lett sick people work there?

I'm pretty sure they are screening at all stores for sick employees. My nephew has cystic fibrosis and coughs constantly. It's a bit harsh to assume someone is sick from a cough. Hopefully you get the answers your looking for. God bless.

My two kids have/had cystic fibrous and they coughed constantly.. Seasonal allergies also have people coughing as there sinuses are draining down the backs of their throats...
