I all, lo has just arrived and I think I've royally peeved off Mam. She came 3 hours early on one day last week, Mam asked in a text, and today she is doing an extra 2 hours. Mam was going to keep her off tomorrow as dads birthday. She asked if the extra hours would cover tomorrow so she doesn't pay for the hours she wasn't going to use tomorrow, if that makes sense. I've swapped days in the past when I've had notice, however, I've explained that I can't fill the space tomorrow at such short notice so I can't transfer the hours and will charge for extra + the full day tomorrow. Now I feel like a wicked witch! She's said Lo might come tomorrow after all which is fine. Was I in the wrong to charge for the full day tomorrow?
