We have a virulent sickness bug in our house, first person had it this time last week and last person has it at the moment. I have obviously told our cleaner about it and given her the option of not coming, assuming she won't want to risk the germs. What is the correct thing to do about paying her ? I have offered her half the money for staying away, but honestly don't know if this is fair. What's the verdict? She has been with us a few months and is good.
