Can unions campaign on environmental issues?

You do not have to choose between a greener workplace and a safe, paid job. Your union can press for both. A kitchen that makes you ill, fumes on the warehouse floor or a depot closure linked to decarbonisation are employment issues. But a walkout over government climate policy alone puts your job at risk.

The trade dispute test

Calling a campaign “green” neither gives it protection nor takes protection away. For industrial action, section 244 of the Trade Union and Labour Relations (Consolidation) Act 1992 asks whether there is a dispute between workers and their employer which relates “wholly or mainly” to a listed employment matter. A narrow statutory exception can treat certain disputes with a government minister as employer disputes. It is not permission for a general political strike.

The list includes terms and conditions, physical working conditions, employment and dismissal, allocation of work, discipline, union membership, union facilities and negotiation or consultation machinery. Heat, ventilation and jobs threatened by a green transition can fall within it. The real substance of the dispute matters, not a reference to section 244 on a leaflet.

A qualifying dispute is only the first condition for strike protection. The union must also meet the applicable ballot, notice and other industrial-action requirements. Section 219 provides immunity from specified civil claims, not a licence for every act during a campaign. Employees taking protected industrial action have dismissal protection under section 238A. Wider campaigning and peaceful protest are separate from these strike rules.

What your union can bargain over

The statutory definition of collective bargaining includes physical working conditions. But the recognition agreement determines what your employer has agreed to negotiate; recognition does not compel bargaining on every section 244 subject.

A cleaner needs safer chemicals. A warehouse picker needs ventilation under a metal roof. Care staff need heating through a night shift. These are demands about the job, not an employer’s public image.

Ask your rep to check the agreement or negotiate a wider remit. Section 181 provides bargaining-relevant information rights, subject to statutory conditions and exceptions, not unrestricted access to carbon accounts. See our information disclosure guide.

Green reps and paid time off

A “green” rep has no dedicated statutory paid-time-off right. Their duties and workplace agreements decide whether time is paid.

The Acas Code on time off distinguishes duties from activities:

Union duties. Under section 168, employee officials of recognised independent unions get reasonable paid time off for qualifying duties. These include negotiations within recognition, agreed related functions and certain statutory consultation duties. Relevant training must be union- or TUC-approved. A heat-plan negotiation can qualify.

Union activities. Under section 170, employees in an independent union recognised for their group get reasonable activity time off, without a statutory right to pay. Agreements can provide payment. This excludes industrial action and does not cover any green club simply because members belong to a union.

If refused time off, get the reason in writing. Ask your branch to check the agreements and help challenge it. Acas, Citizens Advice and law centres offer further advice routes.

Use your safety reps

For heat, fumes or chemicals, use the existing safety route. Recognised unions can appoint reps under the Safety Representatives and Safety Committees Regulations 1977.

Employers must consult them in good time about measures substantially affecting safety. Reps can inspect workplaces and investigate hazards, complaints and accidents, with paid time for functions and reasonable training. A written request from two or more safety reps requires a safety committee.

A kitchen porter fainting by the fryers, a cleaner struggling with chemical fumes or a farm worker doing heavy work in a heatwave needs a safety response. A sustainability poster is not a substitute.

Without recognition, the 1996 consultation regulations still require consultation with employees directly or elected representatives. The separate Information and Consultation of Employees Regulations 2004 offer a formal route in undertakings with at least 50 employees, subject to request and negotiation requirements.

Heat and danger at work

There is no fixed legal maximum working temperature. That does not let an employer ignore heat stress.

The Workplace Regulations require a reasonable indoor temperature. HSE guidance says normally at least 16°C, or 13°C for severe physical effort, subject to the work. These are not universal statutory cut-offs. The TUC’s proposed maximum of 30°C, or 27°C for strenuous work, is a campaign demand.

At 35°C by the fryers, ask for the heat-risk assessment, water, ventilation and suitable breaks. Record symptoms and tasks alongside temperatures. The employer must assess and control the risk; a thermometer alone does not decide whether work is safe.

Section 44 of the Employment Rights Act 1996 protects workers against detriment for leaving or refusing to return to a workplace, or dangerous part of it, where they reasonably believe there is serious and imminent danger they cannot reasonably be expected to avert. Section 100 gives employees automatic unfair dismissal protection on those grounds. This is not a blanket right to leave when hot. Explain the danger if safe and contact your rep promptly.

If you are punished for green action

A union campaign, a strike and a pollution report have different protections. Work out which activity led to the punishment.

Union membership and activities. Section 146 protects workers against detriment on specified union grounds, including independent union activities at an appropriate time. That generally means outside working hours or with employer consent. Section 152 makes dismissal on protected union grounds automatically unfair for employees, without qualifying service. Save rota changes, messages and explanations; timing is evidence, not proof of the employer’s reason.

Protected industrial action. The 2025 Act removed section 238A’s 12-week limit from 18 February 2026. Dismissal because an employee takes protected action is automatically unfair without that cap. The union must check every applicable requirement. Extended industrial-action detriment protection is scheduled for 30 October, not yet in force. Strike protection does not guarantee strike-day wages.

Environmental whistleblowing. Section 43B covers information you reasonably believe is disclosed in the public interest and tends to show past, present or likely environmental damage. Protection also depends on the recipient and disclosure route; a public accusation is not automatically protected. Workers can have detriment protection under section 47B, and employees automatic unfair dismissal protection under section 103A, without qualifying service. Check our whistleblowing guide before reporting.

Climate belief. Under the Equality Act 2010, a climate belief can be protected. Grainger plc v Nicholson, 2009, sets the criteria: genuinely held; more than a current opinion; concerned with a substantial aspect of human life and behaviour; sufficiently cogent, serious, cohesive and important; worthy of respect in a democratic society and compatible with human dignity and others’ fundamental rights. Employment coverage can include personal-work contracts as well as employees. It does not immunise every act motivated by the belief.

Closures and the just transition

A cleaner at a closing factory needs an answer about next month’s work, not a promise of future green jobs. Unions can negotiate retraining, redeployment and redundancy terms. No law guarantees that every job survives.

Section 188 requires consultation for at least 20 proposed redundancies at one establishment within 90 days or less. The employer must consult the recognised independent union for the affected group, or qualifying employee representatives without recognition, about avoiding dismissals, reducing numbers and mitigating consequences, with a view to agreement.

Consultation must begin in good time, at least 30 days before the first dismissal takes effect for 20 to 99 redundancies, or 45 days for 100 or more. It is not a rubber stamp for a completed decision. From 6 April 2026 the maximum protective award for failure to consult is 180 days’ pay per affected employee, awarded by a tribunal rather than paid automatically.

What changed in 2026, and what comes next

The 2025 Act neither created a statutory green rep nor widened trade disputes to general climate policy. The government timetable records these changes:

1. 18 February 2026Industrial action, in force

   Most Trade Union Act 2016 provisions repealed, including the 50% industrial-action ballot turnout requirement. Notices simplified; 12-week dismissal limit removed.

2. 6 April 2026Consultation and recognition, in force

   Maximum protective award doubled to 180 days. The separate 40% support threshold in recognition ballots removed.

3. 25 August 2026Electronic and workplace ballots, in force

   Available for statutory union ballots. Recognition and derecognition ballots are separately scheduled for 2027; any online poll will not do.

4. 1 October 2026Longer claim limits, in force

   Most new events carry six months minus one day; earlier events generally retain the old limit. Scotland’s contract-claim change follows later.

5. 30 October 2026Access and rep protections, scheduled

   Stronger access rights, further recognition reforms, new rep rights and extended industrial-action detriment protection. Not current rights on 1 October.

6. January 2027Union information duty, scheduled

   Employers due to tell workers about their right to join a union. Future dates remain subject to parliamentary processes.

What to do today

1. Record the problem and demand. Note heat, fumes, changed shifts or threatened jobs, dates, symptoms and management’s response. Keep lawful copies, without taking confidential client or patient information.
2. Contact a rep or union. Ask for a safety inspection or bargaining demand. Without a branch, ask UNISON, GMB, Unite or a sector union who covers your job; gig workers can also approach IWGB.
3. Check recognition and paid time. Ask whether the duties fall within the agreements or safety-rep functions. Keep time-off requests and refusals in writing.
4. Report through the right route. Raise danger with your rep and management if safe. Report unresolved risks to the HSE or relevant local authority, depending on the workplace. Get whistleblowing advice before choosing an environmental regulator or going public.
5. Check proposed action. Have the union check the dispute, ballot and notices before a walkout. Political and secondary-action restrictions still apply.
6. Act promptly if punished. Save rotas, pay records and messages. Ask your union, Acas, Citizens Advice or a law centre about claims and deadlines. Do not wait for a grievance to finish; get advice before resigning.

Do not miss the claim deadline

Acas confirms most pre-1-October-2026 problems retain three months minus one day; most later problems get six months minus one day. An event on 1 October usually gives an initial deadline of 31 March 2027. Claim types and repeated incidents can complicate this. Timely Acas notification for early conciliation can pause the clock; a grievance cannot.

Some dismissal claims permit interim relief to protect income while proceedings continue. Its deadline is only seven days. If dismissed for whistleblowing or union activity, ask your union or a lawyer immediately.

Agency, gig and migrant staff

Automatic unfair dismissal normally requires employee status. An agency worker can be an employee of the agency even if not of the hirer. Losing an assignment is not necessarily the end of your rights.

Workers can have union and safety detriment protection; whistleblowing’s extended worker definition also covers many agency arrangements. The respondent and protection depend on the contracts, working relationship and who punished you. Genuinely self-employed people should not assume coverage.

If your visa is tied to the job, seek employment and immigration advice together before resigning or taking action. Start with your union or Work Rights Centre. See our gig union and agency worker guides.

Scotland and Northern Ireland

England, Wales and Scotland share the main union and employment rules described here. For Scottish employment tribunal breach-of-contract claims, the time limit changes on 9 November 2026: breaches before then normally have three months minus one day, and those on or after that date six months minus one day.

Northern Ireland has separate employment and industrial-relations law. Do not apply the Great Britain reform dates or deadlines to an NI claim. Its trade dispute definition is in Article 96 of the Industrial Relations (Northern Ireland) Order 1992, and environmental disclosures are covered by Article 67B of the Employment Rights (Northern Ireland) Order 1996. Contact the Labour Relations Agency rather than Acas for local conciliation and advice. See our Northern Ireland guide.
