Trade Union Rights

Every worker in Great Britain has the legal right to join the trade union of their choice under the Trade Union and Labour Relations (Consolidation) Act 1992 (TULRCA). Your employer cannot prevent you from joining a union, require you to leave a union as a condition of employment, or offer inducements for you not to join or remain in a union.

You cannot be:

• Dismissed for being a trade union member or for taking part in union activities at an appropriate time
• Selected for redundancy because of union membership or activities
• Subjected to any detriment — for example, being denied training, promotion, or favourable treatment — because of union membership

These protections apply from day one of employment, with no qualifying period. They also apply to dismissed employees who were not yet employed — you cannot be refused a job because of your union membership.

Where a trade union is recognised by an employer, it has the right to bargain collectively on behalf of its members — negotiating pay, hours, holidays, and other terms. Recognition can be voluntary (agreed by the employer) or statutory (imposed through a legal process if the union has sufficient support among the workforce).

Under the statutory recognition procedure in Schedule A1 to TULRCA, a union can apply to the Central Arbitration Committee (CAC) for recognition if it represents at least 10% of the proposed bargaining unit and can show majority support. The process involves a ballot of the relevant workers.

Once a union is recognised, the employer must disclose certain information for collective bargaining purposes and must consult with the union on matters affecting its members. The employer cannot unilaterally change terms and conditions of employment that are subject to collective bargaining without negotiating with the union.

Trade union representatives and members have specific rights to time off under TULRCA:

• Trade union officials (lay reps, shop stewards): Have the right to paid reasonable time off during working hours to carry out trade union duties (negotiating with the employer, representing members at disciplinary hearings) and to receive training for those duties.
• Trade union members: Have the right to unpaid reasonable time off during working hours to participate in trade union activities — for example, attending union meetings or voting in union elections.

What is "reasonable" depends on all the circumstances, including operational requirements and the nature of the union activity. Employers cannot unreasonably refuse time off for trade union duties or activities.

The right to be accompanied by a trade union rep (or colleague) at a disciplinary or grievance hearing — which applies to all workers, whether union members or not — is a separate right under the Employment Relations Act 1999.

The Employment Rights Bill 2024 was one of the most significant pieces of employment legislation introduced in decades. It contained a number of provisions specifically strengthening trade union rights and collective bargaining, building on the framework in TULRCA 1992.

Key proposals in the Bill affecting trade union rights included:

• Repeal of the minimum service levels framework introduced by the Strikes (Minimum Service Levels) Act 2023 — which had required certain workers in key public services to continue working during strikes — subject to the Bill receiving Royal Assent
• Simplification of trade union recognition — reducing the bureaucratic hurdles to statutory recognition and lowering the threshold in some circumstances
• Electronic balloting — enabling trade unions to use electronic and workplace ballots for industrial action, reducing the logistical barriers to lawful strike action
• Repeal of the 50% turnout threshold for industrial action ballots in important public services, introduced by the Trade Union Act 2016
• Workplace access rights — giving trade unions a right of access to workplaces to recruit and organise members, subject to safeguards

Individual workers should be aware that their rights to join a union and to be protected from detriment for doing so remain strong under existing law, and the Bill was expected to reinforce and extend these protections. Monitor the legislation.gov.uk website and Acas guidance for updates as the Bill's provisions are enacted and implemented.

In the meantime, the practical protections under TULRCA 1992 and the Employment Relations Act 1999 remain fully operative. Specifically:

• If your employer attempts to offer you an inducement — such as a pay rise or bonus — to give up collectively agreed terms or not to use union representation, this is unlawful under section 145B of TULRCA 1992. You can bring a claim for a prescribed amount in the Employment Tribunal.
• Trade union learning representatives — union reps specifically trained to support workplace learning and skills development — have the same paid time-off rights as other lay representatives. Acas publishes a code of practice on trade union time off rights that explains what is reasonable in different circumstances.
• If your employer blacklists you (refuses to employ, dismisses, or victimises you on grounds of trade union membership or activities by maintaining a prohibited list), this is a serious civil and potentially criminal matter under the Employment Relations Act 1999 (Blacklists) Regulations 2010.

For workers in sectors where union membership has historically been lower — such as the gig economy, retail, and hospitality — the expanded workplace access rights proposed in the Employment Rights Bill 2024 are particularly significant. If the Bill's provisions are enacted, unions will be able to enter workplaces to explain the benefits of membership to workers who may never have been approached before. The Fair Work Agency, also proposed in the Bill, will have enforcement powers over labour market obligations including those relating to collective rights. Workers who believe their employer is actively discouraging union membership — for example, through anti-union briefings, pressure on supervisors not to join, or informal threats about the consequences of organising — should document all such conduct carefully. Such conduct may already be unlawful under existing detriment provisions and will be further strengthened if the Bill's proposals are implemented in full. The TUC provides guidance for workers on understanding and asserting their collective rights, and can signpost to affiliated unions in specific industries and sectors. Joining a union before a dispute arises — rather than only after — gives you access to representation, legal support, and collective strength when you need it most.
