She can ask to be compensated sure, and I can politely decline. In the end, that is what happened.No...
You know first hand she's a SW and that her time should be compensated. Not having to compensate her for her time on a trip is a privilege; you will know if you are the lucky one. You can't assume you won't have to pay her.
However, when the above mentioned SW talks alot about how she would love to come along on a ski trip and I make it clear that I wont ski with her during the day except for an hour so she doesnt feel abandoned, etc. She keeps asking if she can come along, I guess I assumed she would not expect to be compensated for 8 hours a day. But I agree she has to "right" to ask and I have the right to say no thank you.
All I said is it might be construed as "dangling". Just like in the reverse.
ultimately, you and I both agree.
