Reed Smith Newsletters

Welcome to our monthly newsletter, with a summary of the latest news and developments in UK employment law.

Our May 2025 update looks at new guidance on single-sex workplace facilities (toilets and changing rooms) following last month’s Supreme Court decision on the definition of ‘sex’, as well as the usual round-up of interesting cases. We also provide details of two important consultations on equality issues, allowing interested parties to have their say and help shape legislation around pay gap reporting and discrimination before the June deadlines.

Equality – definition of ‘sex’: As reported in our April update, the Supreme Cout has ruled that the definition of ‘man’, ‘woman’ and ‘sex’ in the Equality Act 2010 (EqA) refer to the person’s biological sex and a gender recognition certificate (GRC) will not alter that. In making its ruling, the Supreme Court noted that trans people (with or without a GRC) were protected from discrimination under the gender reassignment provisions of the EqA, and that many of the sex discrimination protections extended to perception or association with a particular gender. The Equality and Human Rights Commission (EHRC) has issued interim guidance (see below) in immediate response to the judgment, and there are reports of plans to challenge the decision in the European Court of Human Rights.

Sex discrimination: A female claimant alleged indirect sex discrimination when, following a restructure, she was required to travel for work once a month. As the primary carer for her two young children, she argued that the requirement put her, as a woman, at a disadvantage. Overturning the Employment Tribunal (ET)’s decision, the Employment Appeal Tribunal (EAT) concluded that while the ET was entitled to consider the childcare disparity (i.e., that women are more likely to take on a greater share of childcare responsibilities), the travel requirement in this particular case did not intrinsically disadvantage women and so the ‘group disadvantage’ part of the test had not been made out.
