Detailed guide to recent developments in workplace discrimination law in England and Wales, including legislative reform under the Employment Rights Act 2025, Supreme Court definitions of sex, new harassment prevention duties, tribunal practice updates, and practical implications for employers and employees.
Workplace discrimination law in England and Wales continues to evolve through new legislation, case law developments and regulatory guidance. The legal landscape is shaped by changes to statutory duties, high‑profile tribunal decisions, and reforms designed to strengthen employee protections. This article provides a clear, up‑to‑date overview of the most significant developments affecting discrimination rights - legal definitions, employer obligations, tribunal processes, and practical implications for employees, employers, solicitors, and HR professionals.
Legislative Reform: Employment Rights Act 2025
A major development is the Employment Rights Act 2025, which received Royal Assent on 18 December 2025. This Act represents one of the most significant overhauls of UK workplace rights in decades and introduces new protections and clearer statutory obligations for workers. Among its reforms are provisions strengthening anti‑discrimination and harassment protections, modernising employment rights and updating enforcement frameworks. The new legislation also includes measures that impact how workplace discrimination claims are handled, including mechanisms to protect victims and encourage compliance by employers.
Non‑Disclosure Agreements and Misconduct
As part of wider employment reform, the law now prevents employers from using non‑disclosure agreements (NDAs) to shield misconduct, harassment or discrimination. This means clauses that seek to silence workers who complain about discriminatory conduct or the employer's response are void to the extent that they prevent meaningful disclosure. Employers cannot contract out of legal rights to make a complaint or pursue a claim in good faith.
Supreme Court Guidance: Sex and Protected Characteristics
In April 2025, the UK Supreme Court issued a landmark ruling confirming that the definitions of “man”, “woman” and “sex” in the Equality Act 2010 refer to biological sex, not gender identity, for the purposes of discrimination claims. This development clarifies how tribunals and courts interpret protected characteristics in discrimination cases, affecting disputes involving sex and gender reassignment. The ruling has generated consultation and guidance work by the Equality and Human Rights Commission (EHRC) to support employers in applying the law consistently.
EHRC Guidance on Single‑Sex Spaces
Following the Supreme Court decision, the EHRC has been adapting statutory guidance on single‑sex services and workplace facilities to balance legal compliance with dignity and safety considerations. Recent proposals aim to ensure the guidance is clear, practical and legally sound, reflecting both the court's ruling and the need to avoid disproportionate burdens for businesses.
Judicial and Tribunal Decisions
Trans‑Related Discrimination Claims
Recent tribunal cases highlight evolving practical issues around discrimination claims involving transgender and non‑binary employees. For example, in Hutchison and others v County Durham and Darlington NHS Trust, an employment tribunal found that requiring female nurses to share changing facilities with a transgender woman constituted harassment and discrimination, emphasising respect for dignity and workplace arrangements. Decisions like this underscore how tribunals balance competing rights and practical workplace considerations in equality law.
Another tribunal decision in early 2026 dealing with a non‑binary claimant illustrated the statutory requirements for proving the protected characteristic of gender reassignment. In that case, the tribunal found that steps such as changing name and pronouns did not, on the evidence, satisfy the statutory test for gender reassignment protection under the Equality Act.
High‑Profile Case Law on Discrimination and Employment Practices
Although not resolved until late 2025, the Court of Appeal has dismissed the appeal in Bailey v Stonewall, a case involving claims of discrimination in a professional context where alleged ideological influence was at issue. The Court upheld the tribunal and Employment Appeal Tribunal findings that there was no unlawful discrimination arising from the investigation and outcome in that context. Cases like Bailey show the complexity of discrimination disputes where free expression, professional obligations and equality rights intersect.
Strengthened Employer Duties: Preventing Harassment
Positive Duty to Prevent Sexual Harassment
A significant statutory change occurred in October 2024 with the introduction of a positive duty under the Worker Protection (Amendment of Equality Act 2010) Act 2023. This requires employers to take proactive and reasonable steps to prevent sexual harassment in the workplace, not merely react to incidents once they occur. Employers must demonstrate targeted proactive measures - such as training, effective policies and complaint mechanisms - to avoid liability, and tribunals may uplift compensation awards by up to 25% for failures to comply.
Government Reform and Future Strengthening
Proposals accompanying the Employment Rights Bill envisage enhancing this duty further. Future reforms may require employers to take all reasonable steps to prevent sexual harassment and extend employer liability to harassment by third parties, such as clients or customers at work. The reforms could also link certain harassment disclosures to protected whistleblowing disclosures, broadening protections for those reporting misconduct.
Employer Reporting and Transparency Initiatives
Ethnicity and Disability Pay Gap Reporting
The UK Government has consulted on proposals for mandatory ethnicity and disability pay gap reporting for larger employers (typically those with 250 or more employees). If adopted, these reporting duties would mirror the existing gender pay gap obligations and provide more transparency around disparities in pay and representation. Employers should monitor these developments as they would create additional compliance requirements and highlight discrimination risks in pay and progression.
Tribunal System and Claim Dynamics
Claim Volumes and Tribunal Backlogs
Employment tribunal statistics for 2024–25 show rising numbers of claims lodged and open at tribunals, including discrimination claims. A significant backlog and increased volume contribute to longer waiting times for hearings. These systemic pressures highlight the importance of early resolution mechanisms such as Acas early conciliation and alternative dispute resolution to manage caseload pressures and reduce delays in justice.
Time Limits and Early Conciliation
As part of procedural changes, the Employment Tribunals (Early Conciliation: Exemptions and Rules of Procedure) (Amendment) Regulations 2025 extended the maximum Acas early conciliation period from six to 12 weeks for claims notified from 1 December 2025. This extended period gives more time for parties to settle disputes before engaging in full tribunal proceedings, though it does not change the ultimate claim deadlines beyond conciliation pausing the statutory limitation period.
Practical Implications for Employers
- Review policies on sexual harassment, discrimination and equality to ensure proactive compliance with the positive duty and forthcoming reforms.
- Adapt workplace training to reflect latest statutory standards and tribunal interpretations, especially around protected characteristics and harassment.
- Prepare for reporting requirements, including potential new pay gap disclosures.
- Engage with Acas early to resolve potential disputes and reduce litigation risk.
Practical Implications for Employees
- Understand how protected characteristics-especially sex and gender reassignment-are defined by recent case law.
- Take early steps to log complaints and seek early conciliation where appropriate.
- Consider the evidential burden and proactive duties when asserting claims, such as in harassment cases.
Common Questions
How has sexual harassment law changed?
Employers must now take proactive, documented reasonable steps to prevent sexual harassment, not only respond to complaints. Failure to do so can lead to tribunal sanctions and higher compensation awards.
Does the Supreme Court ruling affect transgender rights at work?
Yes. The ruling confirms that “sex” under the Equality Act refers to biological sex. This affects how discrimination claims involving gender identity and related facilities are assessed, and guidance continues to evolve.
Will tribunals see more discrimination claims?
Statistics show a rising number of tribunal claims overall, with discrimination claims contributing to growing caseloads, which can lead to delays. Early resolution through conciliation remains an important tool.
Final Thoughts
Recent developments in workplace discrimination law in England and Wales reflect a dynamic legal environment. Legislative reform, case law on protected characteristics, strengthened duties on harassment prevention, evolving tribunal processes, and enhanced reporting obligations all shape how discrimination claims are pursued and defended. Both employers and employees must stay informed of these developments to manage risk, comply with legal duties, and uphold workplace equality effectively.
