School trip, 5 adults (1 staff, rest volunteers), 35 kids (secondary age). First aider needed on the coach. I am first aid trained and have been asked to go. I'd be in overall charge of everything. I will be 33 weeks pregnant.
AIBU to refuse to go? I know it's unlikely the baby would come then but I am already uncomfortable and working almost 24/7 for three days will pretty much do me in I think, and if I have any pregnancy issues they'd be left without a first aider anyway. There are other first aid trained staff but not that deal with the kids with the same frequency / have the same experience (though the volunteers do have that, just not the first aid).
