My NF is very kind, appreciative, and overall nice to work for. However, MB often will say “if you get bored, can you deep clean all the sinks?” or “if you get bored, can you deep clean all the cabinets?” or “can you mop the whole house?” or “maybe you can reorganize all our hall closets soon”. I work with an agency which is how I found this family therefore we have a contract. None of these duties are on there. I was hired on as a nanny only (and am paid as a nanny only). Not a housekeeper or assistant. The baby naps 3-4 times a day which is when I get my other cleaning duties finished and when I’m done with everything, I read my book until she wakes up. Sometimes I will do these extra things to be nice but I do not put them on my to-do list. How can I nip this in the bud without being rude? They work with me a lot on planned vacation days, etc. + I have never called out or been late but I don’t want this to get worse.
