I work for an elderly couple, one has dementia. Their son lives in another state and will be bringing his wife and kids to stay and "play" and vacation. They have done this before and took advantage of me asking me to do THEIR laundry and dishes etc. I am here to care for the parents....NOT a maid. I also find I have resentment for them taking advantage of personal care attendants, so they can go off and play all day. Why can't they just stay and do fun things/ take care of their folks at home? They're only here for a week. It baffles me. How can I gently approach the issue with them/ my employer?
