OP, I’m a teacher. In your shoes, I would be really upset to be shouted at and it would prey on my mind. I’d also be doing a bit of fizzing with injustice. I totally understand.
I also see if the teacher was administering SATS that they may have been under a lot of pressure at that moment - if I were the teacher, I would be mortified by my own behaviour and feeling terrible about it. She might be!
The school is at fault for poor organisation/communication. I’m in secondary so we are very used to isolating exam areas and keeping silent conditions free from disruption. Primary schools may not have the same capacity, so that’s unfortunate. Mentioning it might be helpful so that the school address the problem and further tests this week aren’t disrupted by the nursery run.
So, I have sympathy for both sides and don’t feel the need to demonise anyone in this scenario. Not because all teachers are saints and deserve a free rein to do as they please or that we are the most stressed of all professions, but just that sometimes people do make a mistake and this isn’t the worst one imaginable, though I do see why the OP is upset.
Two comments have really stood out to me though. OP, you said that as your role is ‘customer facing’ you wouldn’t get away with this at work. Parents and children aren’t customers and education isn’t a product. The customer service approach to schools is a poisonous one, largely responsible for many of the problems facing the profession at the moment. Children are not components in a factory chain which we can mould to an expected and predictable result. We also don’t work at parents’ convenience in the way that a business might. I treat parents politely and professionally, but I am not providing a service to them. They don’t have a right to dictate to me or vice versa. That doesn’t mean I think this teacher had a right to shout at anyone, but there is a distinction between public services like teachers/police/doctors/nurses etc and private sector businesses built on an customer service model. It’s very problematic for all public services when the public imagines they can treat us like an unsatisfactory business that needs their custom. It isn’t the same at all.
Finally, the poster who said teachers should get a new career if we can’t handle the stress - we are. In record numbers. There is a monumental crisis in teacher recruitment and retention. If you are someone who says this kind of stuff, ease don’t complain when your child is in a class of 40+ for their GCSEs because there aren’t enough teachers left.
I lied, that wasn’t final! A particular bugbear of mine is the ‘you will be that parent’ doom-mongering so beloved by MN. I’ve beeb teaching over a decade; there is no such thing as ‘that parent’. I understand that parents might have lapses or stressful situations and might not always act totally reasonably. Or they might be a total dickhead. I still don’t refer to them as ‘that parent’ and I never, ever judge a child because of it. For people to say ‘pray your child doesn’t have that teacher if you dare to complain’ is ridiculous. I’ve never known a teacher that would take it out on a child. I’ve had the occasional parent be abominably rude or dictatorial to me and I have never treated their children any differently as a result of it. We don’t have a database of ‘those parents’. Don’t ever be scared of MNers telling you that we do!
