Today I was told that the oldest of three children has lice. They just found out today when at school. My problem is being their nanny do I risk and go into work and risk being exposed to possibly getting lice myself, which I hear is very hard to get rid of, or not. My option via my boss was I could use paid time off. Of course who wants to use their paid time off for something that was unplanned and nobody's fault? Of course I can't afford to just not be paid and take the time off. I don't know what to do at this point. Am I being petty? How do I go about this?
