I'm currently working a full time week over 4 days, I love having this extra day off but more often than not the OH will arrange something so that I end up having errands to run on this day. It seems really unreasonable to refuse to do things (it's normally stuff that can only be done on a week day) but on the other hand I'm really starting to resent working extra hours every day to just do even more on my day off.
AIBU to say I'm not doing it anymore?
