YANBU- trips are bloody hard work, no one should be “expected” to go, and certainly that has never been my experience.
I say this as a teacher who absolutely loves trips, I have organised and been on loads, and nothing beats the sense of satisfaction watching a kid try something for the first time, whether that’s abseiling, skiing, first time on a plane, first time away from home. It’s brilliant.
But it also very much a JOB and hard work!! Imagine being responsible for 60 teenagers on a plane, or walking up the Eiffel Tower, or up a mountain, knowing it is your name on the risk assessment if anything goes wrong?! Fielding the calls from parents in the middle of the night, sitting up til 2am in the hotel corridor making sure they are in their own rooms, or the little knock on the door when you’ve finally fallen asleep at 3am to say someone’s been sick, or is crying, or is self harming.
My kids are older now so it’s not such a big issue, but when they were little I would have really struggled to leave them.
