What do you do if work wants you to come in Covid positive?

Currently have Covid. Tested Positive on Thursday. Cold/flu symptoms. My work paid me for Thursday and today. Told me to come back in on Monday. However I’m sure I’ll still be sick by then. They told me it I don’t come in then they won’t pay me for the days I missed. I need the money. So I guess I’m going in on Monday. I don’t really have a choice do I?

I work for Walmart in the optometry department so I’m going to be up in patient’s faces. 😬
