I'm sorry I don't have any useful advice to offer with regard to this. But I noticed no one had yet replied to your post. So I thought I would. (It's been a couple of days now since you posted this. So perhaps the situation is already resolved?)

This is such a difficult situation because it not only affects your daughter but, potentially, the whole family. One thing you didn't mention was how old your daughter is. You mentioned she's a teen. But you didn't indicate whether or not she's still a minor or if she might perhaps be 18 or 19.

If your daughter is a minor then it seems to me, given the potentially serious consequences, you have both the right & the obligation to explain your concerns clearly but to force your daughter to quit the job if she won't do it voluntarily after discussing the potential lethality of the Covid-19 virus. Taking responsibility for a job is one form of responsibility. But doing what needs to be done to keep the family safe is another form.

On the other hand, if your daughter happens to be 18 or 19, then she is technically an adult & I don't believe you can force her to do anything except perhaps to force her to choose between the job & your home which is something I'm sure you'd be loth to do. However extreme circumstances sometimes require extreme responses.

I wish I had something more useful to offer with regard to this. Perhaps other PC members will yet have other suggestions they'll be able to share. Best wishes...
