The Employment Rights Act 2025 (ERA 2025) is less a technical update than a change in what good management is expected to look like under scrutiny. It tightens the link between culture, governance and day-to-day decision-making: what managers say, record, and escalate becomes part of the organisation’s legal defence.
ERA 2025 introduces a fundamental shift. Organisations are judged on what they did to prevent issues, not just how they responded.
Prevention is the priority. The focus moves to systems, risk awareness, and early action before harm occurs.
The standard on harassment is higher. "All reasonable steps" requires active, ongoing intervention, not tick-box measures.
Liability is broader. Harassment is treated as a systems issue, including risks from third parties and informal settings.
Whistleblowing rules now apply. Sexual harassment reports gain protected status, making initial handling critical.
Confidentiality is changing. The emphasis shifts away from suppressing reporting toward transparency and trust.
Evidence is essential. Organisations must be able to show clear records of decisions and actions.
ERA is a maturity test. The Act challenges how seriously organisations take responsibility for workplace conditions.
The Act is being implemented in phases with early changes expected from 6 April 2026, further duties from October 2026, and additional structural reforms in 2027 which means "readiness" is not a one-off policy refresh but an ongoing shift in behaviours, workflows and evidence.
ERA 2025 at a glanceWhat is ERA 2025? A major UK Act (Royal Assent 18 Dec 2025) that amends and augments existing employment law, including harassment prevention, whistleblowing, sick pay, family leave, tribunal time limits and state enforcement. When do the headline changes land? Key steps in April and October 2026 with additional measures in 2027. Why it matters for managers: The evidential standard rises. Prevention and documented decision‑making are decisive. |
Much has already been written about what the Employment Rights Act 2025 contains. What matters more now is what it reveals about how the UK government expects organisations to behave.
This legislation is not simply an expansion of individual employment rights. It is a restatement of where responsibility sits when harm occurs at work and how far employers are expected to go to prevent it. In doing so, the Act draws a line under an era where culture, compliance and governance could be treated as separate conversations.
Under the new framework, they are inseparable.
One of the most significant changes in the Employment Rights Act is a shift in legal logic. Traditionally, UK employment law has been reactive, assessing how employers responded after a grievance was raised.
Under the Employment Rights Act 2025, the crucial question becomes:
What did the organisation have in place before anything happened?
This shift is clearest in the expected October 2026 duty to take “all reasonable steps” to prevent sexual harassment. This is not simply a higher bar; it is a new mindset. Employers must:
proactively anticipate risk
identify where harm is likely
design targeted controls
Annual training, generic policies or passive reporting channels will no longer be sufficient. The practical test becomes:
Do managers intervene early, respond consistently, and generate credible evidence at the time?
From October 2026, the Employment Rights Act UK requires employers to treat third‑party harassment (from customers, clients, suppliers, contractors) as a workplace risk. Liability arises unless the employer can prove all reasonable steps were taken to prevent harm.
This applies not only to sexual harassment but to harassment connected to any protected characteristic.
High‑risk spaces include:
customer‑facing environments
social events
lone working
digital platforms
informal working interactions
These are areas that have often been under-governed because they fall between HR, operations and compliance. The law increasingly expects these spaces to be actively managed, not merely acknowledged.
One of the most consequential features of the ERA 2025 is the change to whistleblowing law. From April 2026, disclosures relating to sexual harassment may be treated as protected disclosures.
This transforms the first conversation an employee has with their manager when reporting sexual harassment:
This moment (the first disclosure) becomes legally significant since it can be classified as a protected disclose, how the manager responds is critical and it sets the entire legal trajectory.
Even unintended differential treatment may now be viewed as detriment. Managers become pivotal, and informal handling - delays, minimising, suggesting people “work it out”, or informal adjustments - becomes high‑risk.
The safest standard is simple:
document accurately
escalate promptly
avoid off‑record solutions
The Act also challenges longstanding assumptions about confidentiality. There is a difference between discreet handling (which protects people and process) and silence that deters reporting (which creates risk).
From 2027, provisions that try to silence allegations of discrimination or harassment, or how the employer responded, are expected to be void. The direction is clear: trust, clarity and openness are becoming core to defensible governance.
For employers, this requires a cultural shift as much as a legal one. Encouraging people to speak up is not enough if the organisation is not prepared for what happens next, or if employees believe raising concerns will quietly stall their career.
The Act does not just raise expectations; it raises scrutiny. Two practical pressure points stand out:
Organisations will need to show how decisions were made, why particular steps were taken, and whether preventative measures were reviewed and improved over time. The absence of records, rationale or follow-up may itself become a liability. Culture, in this context, is no longer abstract. It is revealed through risk assessments, reporting routes, manager capability, data, and follow-through.
The Act’s themes become real in the ordinary moments where managers create risk unintentionally: a conversation about annual leave, an absence discussion, a conduct concern, a rota change, a probation decision, a complaint that arrives via Teams at 6pm. The manager standard is increasingly process-led:
Absence and leave rights expand in April 2026; informal handling becomes hard to defend under longer time limits.
When issues are sensitive, high‑impact or harassment‑related (including third‑party), it is important to raise these sooner rather than later. Avoid “wait and see” method.
It's best practice to keep contemporaneous notes you’d be happy to show and can be read six months later.
Best practice dictates avoiding informal exceptions on flexibility, scheduling or contract changes; they create inconsistent precedent (and later exposure).
After a harassment disclosure, do not discourage reporting or delay; do not change someone’s working conditions without guidance; route through formal channels promptly.
What you write (including emails, messages and notes) may be obtained and read in context by an auditor or tribunal.
ERA 2025 ultimately asks how seriously you take responsibility for the conditions people work in. Organisations that treat it as a technical update risk missing the signal: the UK now expects employers to actively design safe, fair, respectful workplaces and to prove it through consistent management practice and evidence.
For those that lean in, it’s an opportunity to strengthen trust, resilience and credibility; for those that don’t, it sets a higher bar for accountability and a narrower margin for error.
This duty will be implemented in October 2026 under the Employment Rights Act 2025. Employers must demonstrate proactive, evidenced prevention of sexual harassment.
Yes, from October 2026. If all reasonable steps were not taken to prevent harassment, employers are liable.
Yes, from 6 April 2026, a disclosure about sexual harassment can qualify for whistleblowing protection.
The standard limit moves from three to six months (no earlier than Oct 2026), with ACAS early conciliation extended.
A new state enforcement body (established 7 April 2026) consolidating key labour‑market enforcement and, over time, enforcing holiday pay and SSP, with strong inspection and penalty powers.
