If you work in a school as a teaching assistant, HLTA, cover supervisor or in any other support role, the question of "should I join a union?" applies just as much to you as it does to the teachers you work alongside. Sometimes more — because TA jobs can be more precarious.
Why TAs need to think about this
Most school staff who end up needing union representation didn't see it coming. The most common reasons people get in touch with their union are:
- An allegation from a pupil, parent or colleague.
- A capability concern raised by their line manager.
- A grievance they need to raise about how they're being treated.
- A restructure or redundancy, especially when funding tightens.
- A disciplinary process following an incident.
None of these are unique to teachers. TAs face all of them — and TA roles are often more vulnerable to restructures because school support-staff budgets are usually the first place schools cut. Without representation, you handle these situations alone.
Your right to be accompanied
UK law gives you the right to be accompanied at a formal disciplinary or grievance hearing by either a colleague or a trade union representative. If you're not in a union, you only have the "colleague" option — and most colleagues, however well-meaning, aren't trained in employment law or HR procedure.
An experienced rep can make a real difference to outcomes: helping you understand what's been alleged, what evidence exists, what your options are, and whether to challenge, negotiate or accept.
What are your options?
TAs and other school support staff have more options than teachers do, because both teaching unions and general unions cover this group. The main ones:
- UNISON — the UK's largest public sector union, with the biggest dedicated school-support-staff section. Earnings-banded subs and a long-standing presence in local government and schools.
- GMB — large general union, describes itself as "the union for school support staff". More than 100,000 school members. Active on pay and conditions for support staff.
- Unite the Union — large general union with a school support staff membership. Politically active and Labour-affiliated.
- Community Union — general union, smaller in schools but with an education and early years section. Labour-affiliated.
- NEU — primarily a teaching union but also accepts support staff in some categories. Note: the other unions argue NEU shouldn't be recruiting support staff under a TUC agreement.
- Edapt — not a trade union. An independent membership organisation offering individual employment support (allegations, casework, advice) for school and college staff in England and Wales, including support staff. Apolitical and usually cheaper than a full union subscription.
How to think about choosing
A few questions worth asking yourself:
Do you want collective bargaining on pay?
Local authority support staff pay is negotiated through the National Joint Council (NJC), which includes UNISON, GMB and Unite. If pay bargaining matters to you, those three are the ones at the table. If you work in an academy or trust that's set its own pay, the NJC is less relevant.
Do you want collective action / strikes?
UNISON, GMB and Unite all ballot for industrial action over pay periodically. If you'd want the option, join one of those. If you'd specifically prefer not to be part of organised strike action, an apolitical option like Edapt removes that question entirely.
Do you mind your subs going to political activity?
Community, GMB, UNISON and Unite are all affiliated to the Labour Party, with a political fund you can opt out of. If you want zero political exposure, Edapt is the only major option that doesn't have a political fund at all.
What can you afford?
Support staff subs are usually cheaper than teacher subs. Typical full-time figures: £10–£15/month for general unions, around £10/month for Edapt. Apprentices and students get heavy discounts almost everywhere.
"But the teachers are in a union — why aren't I?"
This is one of the most common questions we get from TAs. There's no good reason for support staff to be underprotected at work compared to teachers. The risks are the same. The available options are different — but they exist, they're affordable, and many of them are designed specifically with support staff in mind.
If you've not yet joined anything, this is worth a couple of hours' attention. After that, you can put it out of your mind.
FAQs
Will my school know which union I'm in?
Not unless you tell them, or unless you need representation in a formal meeting. Membership is your own private business.
Can I get help if something has already happened?
Most unions have a waiting period (often 30–90 days) before they'll represent you on issues that arose before you joined. Edapt has a 90-day waiting period for pre-existing cases. The general rule: join before you need it.
What if I work in multiple schools or do casual hours?
You can still join. Some unions have specific categories for supply and casual workers with reduced fees. Worth asking directly.
What if I'm a TA who's training to become a teacher?
You probably qualify for free or discounted membership as a trainee — read our guide for trainee teachers.
