I blocked my Headteacher on WhatsApp this week

Wow YABBVU. You are still getting paid until the end of August, get off your backside and do the work . You are definitely not suited to teaching!
Incidentally to answer a previous poster a HT can ask you to complete work during the summer holidays. When do you think schemes of work are written, sets assigned etc etc ?

No. sometimes schools take the Mickey. I once left in Dec and was asked to complete reports due in Feb. I did not reply to email and just left. no repercussions.

As SLT in a primary, this paperwork should have been completed way before the end of term. It should have been checked and flagged by the SENCo and bought to your attention. Also, as an ECT, you should have been supported better as you say you were unaware of what you had to do.
I would just do it, but if you can't face going back you really should message and explain rather than ignoring. It really isn't very professional and unfair on the child.

Re leaving teaching - absolutely do it if you can! Best decision I ever made and should have done it sooner (22 years in primary).
The career frequently sucks the life out of you (and your family) and the expectations are becoming increasingly more ridiculous.

How old are you? This isn't how the world works. Your contract hasn't yet finished. Most professionals work more than their contracted hours anyway, capitalism is a bitch. You'll need this reference no matter what your next job is. Don't you need to work to pay the bills? You choose to be a teacher and now you're putting a day in the sunshine ahead of a child with additional needs. What will that missing paperwork mean to them next year? What additional help might they miss out on? Maybe you should find a job where other people's wellbeing doesn't rely on you doing the job well

Unblock her and do the work.

As it is you are now stressed anyway.

Doing the work is the right thing to do. You say you were overwhelmed so perhaps you were asked to do it and forgot - either way it is your professional responsibility to do the paperwork.

Also, head teachers talk to one another so this could jeopardise your future career prospects

I am a teacher. If a teacher fails to complete a necessary task within their directed hours, then of course they have to complete it within school holidays. Teachers are hardly lacking in holiday time, so we really don't have cause to be precious about it.

The OP said:

"I do not recall being told that this needed to be completed. The last half term I found so overwhelming and felt all I was doing was working for most hours in the day."

which, to me, suggests she (or he) missed the communications about the deadline, which is no excuse at all.

I'd check with your union, but I'm not sure that the HT can request you complete any work over the summer holidays.

You never know when your paths will cross or when you need a reference.
Do the paperwork and quickly

Blocking is very unprofessional and the Head must have your email too.
Just complete the work for the child’s’ sake.

Oh my goodness, this was an epic error of judgement. You are still being paid to work there, therefore the Head is still your boss and has every right to ask you to complete an overdue piece of work. Please remember that, not only are you reliant on your Headteacher for a reference, but that all Heads in the area know and talk to each other.

I would strongly advise you to unblock, say that the blocking was an error, and reassure them that you will go in and complete the work asap.

I totally disagree with most of the posters who are viewing this like a contract where you're expected to work your notice. If (and I assume you are as a classroom teacher) you are contracted to 31st August with these weeks now as annual leave then you have zero obligation to be called back in to get a decent reference and head teachers "talking" amongst themselves isn't a lawful reason to insist you respond.
However, assuming this is something within your power to complete (again if not then you should confirm this to the head) then it would be the right thing to do to expend a small amount of time to get sen processes confirmed for the child. However that is not on you to be forced or bullied to do so. Your head teacher is not wrong to "request" you assist to complete but would be wrong to "demand" it and probably speaks to why you're leaving. In any event I wouldn't just block I'd respond to say which course of actions you're taking, politely and professionally and why. Otherwise I do think that's bad form.

(edited for spelling)

The problem is that if you don't do this, it is the child with SEND who will suffer. Do you want that on you conscience?

Very childish and unprofessional to block and ignore.

I don’t agree with most PPs. There is very little anyone can do to force you to compete these tasks and your own mental health is vital: my advice is go to a doctor, explain how stressed work is making you and get signed off until your contract ends.

I can understand your need to draw a firm line under your time at that school BUT as pp have said, you are contracted until 31st August.
Also-as a SEN parent and former SENCO (now deputy in another school as the workload/lack of support for SEN at my former school was making me ill) do, please, do the paperwork. Your evidence could make all the difference to a child and their family and education. Not doing it only impacts them really.
All the best for your supply. It’s a hard profession and getting tougher. But if you find the right school for you it’s brilliant.

I think this is tricky, I am assuming that most of the above posters are not teachers and therefore have no understanding of directed hours. Teachers’ directed hours are within term time and should be set out in the school’s time budget, to ensure teachers do not work more than 1265 hours per year which is our contract. Therefore I think the headteacher is unreasonable to contact you in the school holidays to ask you to do this.

Someone should have been keeping track of this paperwork in term time and should have helped you complete it. Also given you are an ECT I would have expected you to have had support for a task like this. I agree with a previous comment though to politely reply, saying you are unable to return to school in the holidays.

Yes you’re in the wrong, do the work.
i am a TA in an SEN school and Autism Mum, if you didn’t complete work concerning my daughter I’d go ballistic!

It sounds like teaching not for you. But if you refused to complete required work in your notice period and blocked your boss in any other line of work you'd be terminated early for misconduct.

Yeah not sure about that - teachers are paid for a set number of hours and the money shared out over 12 months. Teachers always exceed their hours.

Also nobody notices until three weeks after end of term? Wasn’t that important or somebody would have checked it.

Gallic shrug time. Surely you have an apero.

Will you enjoy your summer holiday, knowing that you haven’t fulfilled the terms of your contract and that your actions may have a negative impact on any reference you receive. Even for supply, you’ll need a positive reference.

This
31st August is the end of the contract NOT the end of term
And all heads know each other, so I wouldn’t want to get a bad name over not completing something.
Be professional and think about these pupils affected
This is a bit of a poor choice on your part I’d say.

'On the last day of work'- his hasn't happened yet. The last day of work is 31st August, when your contract ends. If you are going to shirk your responsibilities, for the most vulnerable, you are definitely not suited and should not begin supply in September. Find a new career.

They should have checked you’d done it before your last working day in July so it’s too late now. They've dropped the ball. The SENCo will have to do it in September now with support from the TAs/new teacher. You could be on holiday for a couple of months for all they know.

That’s poor form from you. Get the laptop and complete the work for the child.
