Supporting employees well and managing legal risk are not opposing priorities — but they can feel that way. Many UK employers struggle to find the right balance: they want to support staff through difficulties, but they are uncertain about how much support they are legally required to provide, how far they can go, and where the line is between genuine support and creating liability for themselves.
The good news is that in most cases, the things that are legally required and the things that are genuinely supportive point in the same direction. A compassionate, structured approach to employee wellbeing is also the approach most likely to withstand legal scrutiny if things go wrong. This guide explains how to achieve both.
Your Legal Duty of Care
UK employers have a legal duty of care to protect the health, safety, and wellbeing of their employees. Under the Health and Safety at Work Act 1974, this duty extends explicitly to mental health as well as physical health. The Management of Health and Safety at Work Regulations 1999 require employers to conduct suitable risk assessments — and the Health and Safety Executive makes clear that work-related stress qualifies as a workplace risk that must be assessed and managed.
A 2025 tribunal decision — Phillips v Aneurin Bevan — confirmed that work-related stress can qualify as a disability under the Equality Act even without a formal psychiatric diagnosis. This significantly expands the potential legal exposure for employers who allow high-stress working conditions to persist without action. Poor mental health now costs UK employers an estimated £42–51 billion annually through absence, turnover, and reduced productivity.
Mental Health: What Employers Must Do
Mental health conditions now account for one in three Fit Notes issued by UK GPs. ACAS is clear that employers must treat mental and physical health as equally important. The practical obligations for employers include:
- Conducting a mental health risk assessment — the HSE’s Management Standards provide a framework for assessing stress risk in six key areas: demands, control, support, relationships, role, and change
- Making reasonable adjustments where an employee’s mental health condition amounts to a disability under the Equality Act — this might include flexible hours, amended duties, a phased return, or reduced workload
- Providing access to support mechanisms — Employee Assistance Programmes (EAPs), occupational health services, and mental health first aiders all form part of a defensible wellbeing framework
- Training managers to recognise mental health concerns and have appropriate conversations — the legal risk of failing to act increases significantly once an employer is aware, or should have been aware, of a problem
Supporting Without Creating Risk
One of the most common concerns employers have is that offering support — particularly around mental health — will somehow be used against them. In practice, the opposite is true. Tribunals look much more favourably on employers who can demonstrate that they identified a concern, offered support, made reasonable adjustments, and documented what they did than on employers who had no structured approach at all.
The key is to be consistent, documented, and proportionate. Support offered to one employee dealing with a particular condition should be available to all employees in comparable circumstances. Adjustments made should be reasonable given the size of the business and the nature of the role. And every step taken should be recorded.
Absence and Return to Work
Absence linked to mental health or other health conditions is one of the most legally sensitive areas for UK employers. Statutory Sick Pay is payable from the first day of absence from April 2026, and employees cannot be dismissed simply for being ill — the capability process must be followed, including genuine consideration of reasonable adjustments and occupational health assessment where appropriate.
Return-to-work processes should be supportive and structured. A phased return — where an employee gradually increases their hours or responsibilities after a period of absence — is one of the most effective tools for sustainable recovery and demonstrates that the employer is meeting their obligation to consider reasonable adjustments.
Maintaining Legal Protection While Supporting Staff
To stay legally protected while supporting your employees effectively, focus on three things: consistency, documentation, and process. Apply the same standards of support to all employees in comparable circumstances — inconsistency is one of the most reliable routes to an Equality Act claim. Document every step — the support offered, the adjustments made, the conversations held, and the reasoning behind decisions. And follow a structured process — whether under the ACAS Code of Practice for conduct issues, or the capability process for health-related matters.
For businesses without in-house HR expertise, navigating this balance is one of the most compelling reasons to access outsourced HR support. A CIPD-qualified consultant can help you structure your approach, document your decisions, and ensure that every step you take is both genuinely supportive and legally defensible.
