We are currently looking for a cleaner. We never had one before, so we know very little about the process. We rang up one lady who advertised via our local convenience store notice board. She came over for an "interview", brought all sorts of ID and promised references. She says she has lots of clients in our area. But it seemed obvious that she is not declaring her earnings for taxes. We asked if we could pay her by direct debit, she declined and asked for cash on the day. We asked if she had insurance and offered to contact the company who insures our house to see if we could add her onto it. She asked us not to bother.
On one hand, she probably does not earn much, even with a busy week, and needs the money that would have gone to taxes. On the other hand, this kind of work feels somehow wrong. We would have been happy to provide "job security" such as a formal contract that would outline such things as holiday pay and notice periods, but this feels weird.
Am I being unreasonable for feeling this way? If she has all the clients she says she has, do most people not mind it?
