She may be willing to up your compensation to give this to you but you need to be cognizant that that is what it would be so she would likely do so in lieu of a raise it something.
If this was part of the original negotiations though (her being paid even if not working), then the MB can't really change that to say that she HAS to make up the days. I think she has just gotten used to the OP willingly trading the days for different ones, which is not guaranteed paid hours, just the MB guaranteeing that she has the chance to WORK that many hours in the week (and being nice and paying even if she doesn't work them all). As long as it was guaranteed PAID and not just available hours to work, then OP is fine with using the excuse that she has other plans or another job on those days. I would actually use the job thing, it would mean you never have those days available and you don't have to keep coming up with regular excuses. Just say you are no longer available on those days.
While I don't always advocate being passive-agressive by using an excuse, since it has been going on for 3 years already, I think this is the easiest way for the MB to get the point and have the OP not have to feel pressured into doing something that she doesn't want to do. If the MB starts to try and get weekend work out of her for days she takes off not needing the OP, then OP should then remind her that the agreement was actually she would be paid even if not used that day, and she needs her weekends free to run errands, spend time with friends and relax so that she is refreshed for the new week on Mondays.
There is the chance that the MB will not like this change, even though it was something she agreed to initially, so OP better be prepared to have to say she will look for a new position instead if her MB suddenly decides that she really wants banking of hours/days exchanged as a regular thing.
