Secondary teacher here. For what it’s worth, I don’t think I’ve ever refused a child going to the loo during my career. Even in a super strict academy, where I would get pulled up on it if someone caught them going to the loo during lessons.
I’m just not comfortable with refusing, especially female students, who may well be asking for other reasons than just relieving themselves.
But there’s equally no point in pretending that it doesn’t fuck up your lessons, and yes, it does piss me off (haha, puns) on the inside.
I’ve never taught in a school with more than two hours between either a break, lunch, or end of the day. Most times, it’s less than two hours. So yes, that is when they should be using the toilet, and it’s your job as parents to remind them of this at home, and encourage them to do so. Because, shockingly, being in their lessons is kind of fucking important. Two hours between toilet trips is really not an inhumane amount of time.
Students with medical needs otherwise is easy, that stuff is communicated to teaching staff, and exceptions such as toilet passes are made.
Honestly, the way some parents go on. And yes, there are of course many jobs where you have to “time your bladder”. As others have previously said, we can’t leave our classrooms to go to the toilet. I think the most I’ve done is make a pretend trip into my stationery cupboard so I could bend double for 30 seconds due to hernia pain. No, I can’t just grab another teacher to watch my class.
