I am secondary and it is draining.
Behaviour in the younger years, answering back, lack of manners, lack of work ethic in about 50% of the students.
Attitude is awful in the older years, Yr 10 rude, lazy (I do have a bottom set so this is often the case for some but its the whole class), I have a group of year 10's targeting me, rude emails, comments as I walk around the school, disruptive behaviour - spoke to one mum and was told the student sometimes takes a dislike to a teacher and will behave like this so I have to accept it.
My year 13's, some put more effort into bugging me to raise a predicted grade than they have done work wise for my course over the past 2 years.
My year 11's are lovely but I have had a lot of them since Yr 9 so we worked through the second lockdown together.
I also volunteer with a youth group and most weeks they are lovely, last week I did point out I don't go to carry on being a teacher - I am blaming the strike day and the full moon!
I do think there is evidence of a distinct lack of parenting during the lockdowns that has made an impact, which isn't being addressed now, I know I gave in more to save all our sanity but have had to wind it back in since. I also have a Yr 3 and Yr 2 child myself, Yr 3 are seriously immature and it drives my eldest nuts.
