Any teachers on here?

Id encourage her to qualify and either seek jobs in private schools here or abroad. Dubai or Australia

I've been a teacher for about 9 years now. I think the first few years (probably until about 4 years in) are the biggest learning curve. She's still new and she should absolutely be receiving support from the SLT. Yes, schools are busy, but it's unacceptable to leave a new, inexperienced teacher with little to no support.
I had a really challenging school and class for my first year. I left in the summer, and went into an office job. I missed teaching so much and went supply teaching for a bit. It was the best thing I did. You get to see which schools are good, which are toxic. I used to accept every single job, just to get my name out as someone who was willing and capable. I know the NQT period has changed since so check before doing anything. I found this to be an invaluable experience and was offered a job in a school I worked for regularly.
I think her next opportunity to leave will be Easter now, but, if she's passionate about teaching and doesn't want to leave, it sounds like she's just in a bad school.
Move around, try supply or another school, not all schools are like hers, there are some lovely ones to work in. And persevere, it definitely gets easier!
I hope she finds her perfect job which helps her grow into a great teacher and makes her happier.

Yes, it’s awful.

I do supply now. Today I went in to the staff room and the teacher I was covering for was crying because her books had been hauled over the coals by SLT. There was a child in her class who had no TA but who absolutely should have had a one to one or been in a special school.

This is what it’s like now.

I moved to secondary. Much better workload. Fewer swearing parents but much more aggressive pupils.

the private sector is nicer but equally hard.

It's a really tough career.

For secondary teaching it's about 10 to 11 hours per 1 day you work. I do an 80% timetable over 5 days and it's 40 to 45 hours a week. I just couldn't do 5 days a week but LOVE my job, so the 20% pay cut makes the job feasible without burn out.

What's important is a supportive SLT. Without that, the job is awful. I left my previous school due to horrendous management who were just weak and pathetic.

Whinging parents is normal. She just needs to learn not to take it personally. When you have a child that takes no accountability for their own behaviour then you only usually have to look to the parents to see why.

She should speak to the SLT to let them know how she is feeling and ask for support. As an ECT her mentor should also be supporting her.

I’m a teacher in Australia- the students with additional needs sound the same but no my school wouldn’t allow a teacher to be scared of parents that’s not on my SLT would intervene here. So she either needs to find a different school, SLT. ….. or country

Education is broken everywhere and all you need to do is read a thread like the one where a student is skipping classes to see how teachers and schools are treated

Sorry but that sounds fairly standard for teaching nowadays. I retired 3 years ago and don't regret it at all.
I don't know why anyone would consider teaching as a career unless there are vast changes to the current situation.

Yeah that's pretty much the vibe in teaching at the moment. I had a cry this afternoon.
I actually teach at one of the good schools, so I'm told.

Teaching is hard. I taught secondary for three decades, Head of English and safeguarding lead. Regularly worked 60 plus hours a week, in school. Another 15 hours at home marking and planning. It’s a baptism of fire for nqts, it will make or break them. In my experience, it’s 30% about teaching and 70% about jumping through impossible SLT hoops, trying to meet unrealistic targets. The only thing I missed after quitting was the students. Which is why I wanted to teach in the first place.

It’s what some schools are like. There are other schools with largely reasonable parents and supportive SLTs. I think your sister has been unlucky. There are better primary teaching jobs out there.

Could she try another school? I’ve recently changed schools after decades in a rough school, and my life is very different.

It’s awful. I’ve been teaching for nearly 20 years and I’m seriously considering my options now as I don’t think I can do it for much longer :(

Teaching in the UK is REALLY hard.

Workload
Expectations
SLT (usually crap)
Behaviour
Extra duties
Evidencing
Parents

The first few years will have you on your knees. You do get better at managing it. But it's always going to be a 50/60 hour a week job, minimum.

The kids are the only thing that make it worth it.

All of that sounds pretty much like what it is now.
