The Employment Rights Act 2025 marks a clear shift in the balance between employers and trade unions. It strengthens union rights, lowers barriers to organising, and gives unions more access to your workforce. This is not a technical tweak. It changes how employee voice shows up in your business. Here is what has changed, and where the real risks sit.

What has changed?

First, access. Unions now have stronger rights to enter workplaces and engage with staff members. That includes physical and, in some cases, digital access. Employers have less room to refuse. You will need a clear, lawful basis to say no.

Second, recognition. The process for a union to become formally recognised is easier. Recognition means the employer must negotiate with the union on pay, hours and holidays. Thresholds for support have shifted, and procedural hurdles have reduced. In practice, more applications will get through the door and more will succeed.

Third, protections and industrial action. The Act expands protection for union activity. Employees gain stronger safeguards against detriment or dismissal for taking part. Rules around industrial action have also relaxed. Balloting and notice requirements have been simplified. That makes it easier to organise lawful action, and harder for employers to challenge it.

These changes work together. Easier access feeds organising. Easier organising feeds recognition. Stronger protections make participation less risky for employees.

What does this mean in practice?

Expect more union presence in your workplaces. Not just in traditional sectors. Professional and tech environments are no longer outliers. If you have not seen union activity before, that may change quickly.

Recognition requests will rise. Some will be well organised and backed by data on employee support. If you respond late or inconsistently, you risk losing control of the process. Once recognition lands, your operating model changes. Decision-making on pay and terms becomes slower and more formal.

Disputes will feel different. Issues that you might have resolved informally can escalate into collective disputes. Industrial action becomes a credible lever rather than a distant threat. Even short, targeted action can disrupt operations and damage customer relationships.

There is also reputational risk. How you respond to union activity is visible to your workforce and, often, the public. Heavy-handed responses can undermine culture and brand. But passive responses carry risk too. Inconsistent handling creates evidence problems if matters reach a tribunal.

Finally, governance matters. Boards will need clear oversight of workforce relations. This is not just an HR issue. It affects cost, delivery, and risk appetite.

What should you do?

• Audit your current exposure, map where union interest is likely to emerge.
• Review policies on access and engagement, make sure managers apply them consistently.
• Train senior and line managers on lawful responses to organising activity.
• Stress test your recognition response plan, including data, communications, and timelines.
• Prepare for industrial action scenarios, including continuity plans and stakeholder messaging.
• Tighten your evidence trail, record decisions and rationale in real time.

This is a shift in workplace relations, not a passing phase. Employers who act early will keep their options open and avoid reactive decisions under pressure.

More changes to trade union recognition are expected later this year.

Where does it apply?

The trade union measures apply in England, Scotland and Wales. They do not apply in Northern Ireland, where legislation relating to trade unions is devolved.
