So my MIL has the kids for me next Monday while I have 3 job interviews that afternoon. she's now told me she has to attend her sister in laws, brothers funeral. My parents both work so can't cover my childcare (half-term here). Told my partner to tell his mum she can't go but he said she's entitled to and people don't owe me anything. He's now potentially taking the day off even though she had already agreed to the childcare first AIBU to be annoyed that they are prioritising this funeral over the childcare?
