How to join a trade union: what happens step by step

How to join a trade union: what happens step by step

Joining a union takes about three minutes, and almost nobody knows what happens in the three months afterwards. That gap is where most of the disappointment lives, because people join at the moment trouble starts and expect help the same afternoon. This page sets out every stage in order: what you pay, what you get on day one, what starts at three months, and what it costs if you need help before then. Read it before you join and nothing on this list will surprise you later.

Step one: check nobody already covers you

Some employers recognise a union already, usually named in your contract or on a poster in the staff room. Where that union covers your role, it negotiates your pay and it will represent you, and joining a second union rarely adds anything.

Most people have no such cover. If your employer recognises nobody, or recognises a union that does not cover your grade, you are choosing your own union rather than joining the house one. That choice is yours alone, and your employer has no say in it.

Step two: join online

You join online, on a phone, in a few minutes. You give your name, your contact details, your employer’s name and your job title, and you set up the payment.

The employer details exist for one reason: a representative who already understands the sector and the policies is faster than one starting cold. Those details go no further. Nothing is sent to your employer and nothing is published, because your membership is nobody’s business but yours.

What you pay

Membership costs £25 for the first month, then £15 a month. That is about £3.46 a week, and it does not rise because you use it.

There is no joining fee, no minimum term and no exit fee. If you are still weighing the price against the alternatives, whether joining is worth it sets them side by side. You can stop whenever you like, which matters, because the only fair way to sell membership is to make leaving easy.

What starts on day one

From the moment you join you have the protection of the law as a union member, which begins immediately and does not depend on length of service. You also have full access to the guidance library, the members’ group and the template letters, so you can answer most everyday questions yourself.

From day oneFrom month four
Legal protection as a union memberAdvice on your own situation
Members’ guides and template lettersA legally trained representative assigned to you
Members’ group accessRepresentation at disciplinary and grievance hearings
Contract and policy explainersSupport through appeals and conciliation

The line between those two columns is the three-month rule, and it is the part worth understanding properly.

The three-month rule

Advice and representation on your own case are included once you have been a member for three months. Before that point, the guides and the group are yours, but a representative is not.

The reason is arithmetic, not meanness. Representation is paid for by the fees of members who never need it, so a union that helps everybody from day one funds nothing and collapses within a year.

Three months, then everything.

What it costs if you need help sooner

If you need advice or representation inside your first three months, there is a surcharge of £237, in effect since 1 July 2026. It is not reimbursed.

That figure is not a penalty, it is the real cost of representing someone who has joined mid-problem. It also equates to roughly eighteen months of membership, which makes the arithmetic obvious: joining before anything goes wrong is far cheaper than joining after.

You can still join once trouble has started, and people do it every week. You will simply pay for the position you are in.

Do you have to tell your employer?

No. There is no duty to tell your employer you have joined, and no box to tick. If anyone at work asks, you do not have to answer.

Your membership becomes visible only when you choose to use it, usually when you take a representative into a formal hearing. Even then, the law protects you, and what your employer can and cannot do about your membership sets out exactly how.

Changing jobs, and cancelling

Your membership follows you, not your job. Tell us your new employer and job title and the cover continues without a break, which matters most in the first weeks of a new role when you have fewest rights.

Cancelling takes one message and stops the next payment. If you rejoin later, the three-month clock starts again, so continuous membership is worth more than it costs.

FAQs

How long does joining take?

About three minutes online. Your membership starts as soon as the first payment goes through.

Can I join if I am already in a disciplinary process?

Yes. You will pay the £237 surcharge for help needed inside your first three months. Read what happens at a disciplinary hearing while you decide, because the timetable moves fast once a letter arrives.

Can I bring a representative to any meeting?

The statutory right to be accompanied covers formal disciplinary and grievance hearings. Many employers allow it more widely, and the right to be accompanied explains where the line falls.

Does my employer find out?

Only if you tell them or you bring a representative to a hearing. Nothing is sent to them when you join.

What if I am off sick when I join?

You can join while signed off, and the same three-month rule applies. Statutory sick pay covers what you should be paid meanwhile.

How the National Employees Union can help

The National Employees Union represents employees across the United Kingdom, and it is built on fixing problems rather than fighting over them. After three months you have a legally trained representative who will read your employer’s policy, prepare your case with you, attend your hearings, and hold the process to the procedure your employer wrote.

Before then, you have the guides, the templates and the group, which resolve more situations than most people expect. For the full picture, read what a trade union does.

National Employees Union was formed in September 2021 in response to Regulations requiring care workers and NHS staff to be vaccinated, in order to keep their jobs. Major trade unions had abandoned 40,000 care workers and 100,000 NHS staff.

We questioned the Regulations on the legal basis that they were beyond the powers of parliament, discriminatory, and a violation of fundamental human rights.

As a result we represented hundreds of healthcare professionals in formal meetings, before the Regulations were revoked on 15 March 2022.

Since then we have advised and represented members on a wide range of issues in almost every workplace sector in the UK, including: banking, construction, councils, fast food, government departments, healthcare, hospitality, mining, off-shore, retail, shipping, and teaching.

Legal

Every worker has the legal right to be represented by the trade union of their choice.

Trade unions only need to be recognised for collective bargaining about holidays, hours, or pay.

On 9 May 2023 the Certification Officer for Trade Unions and Employers’ Associations entered the National Employees Union in the Registered List of trade unions.
