Mental Health at Work: More Than a Wellbeing Conversation

Over the last few years, employers have made huge strides in opening up conversations about mental health. We talk more, we listen more, and we understand far better how pressures inside and outside work can affect someone’s wellbeing. But while mental health is often framed as a well-being issue, there’s a part of the conversation many employers still miss:

Mental health can trigger legal responsibilities, and the consequences of getting it wrong are significant.

Numerous tribunal cases now involve depression, anxiety and work-related stress. What starts as a wellbeing discussion can quickly become a legal matter if an organisation isn’t following the right procedures.

This is especially true when absence comes into the picture.

Why Mental Health Is Becoming a Legal Hotspot for Employers

Work-related stress and mental ill-health are rising steadily. That means managers are holding more sensitive conversations, HR is seeing more complex cases, and organisations are under pressure to respond correctly. And this is where things can slip.

Many employers take a supportive, informal approach at the beginning. But problems arise when:

• There’s no record of conversations
• Assumptions are made about someone’s health
• Occupational Health referrals are delayed
• “Light-touch” approaches replace formal procedures
• Adjustments are never explored or documented

The Equality Act: What It Means for Mental Health

Under the Equality Act 2010, some mental health conditions may be legally classed as a disability.

This applies when the condition:

• Has a substantial, long-term impact on daily life, and is expected to last at least 12 months.

Depression, anxiety disorders, PTSD and bipolar disorder are all examples where the threshold may be met. If that happens, employers must:

• Consider reasonable adjustments
• Avoid discriminatory treatment
• Make decisions informed by medical evidence
• Follow a fair and consistent process for absence management

Absence Management: Where the Risks Really Sit

Absence linked to mental health can be complicated. Someone may be off for a short period but have an underlying long-term condition. Someone else may return to work before they’re fully ready. Others may need changes to their working pattern that have never been discussed.

The biggest risks appear when:

• Absence triggers are applied mechanically
• Managers assume “fine now” means “fine permanently”
• The workload or environment is never reviewed
• The return-to-work meeting is rushed or undocumented

It is often how the process was handled, not the decision itself, that causes claims. And unfortunately, absence is where the gap between wellbeing intentions and legal obligations becomes clearest.

What Occupational Health Brings to The Table

Occupational Health (OH) is one of the most valuable tools an employer has, yet it’s still underused.

OH gives clarity on:

• How the condition affects the employee
• Whether it may be a disability
• Recommended reasonable adjustments
• The employee’s fitness for work
• How performance or attendance should be managed

Without this advice, employers are effectively guessing, and tribunals are quick to notice when decisions weren’t evidence-based.

An early OH referral can prevent unnecessary disputes, misunderstandings and escalation.

Why Documentation Matters More Than Ever 

In almost every mental health–related case that ends up in dispute, the same issue appears:

There’s no written evidence of what was said, agreed or offered.

You may have acted fairly. You may have supported the employee well. But without records, proving that becomes incredibly difficult.

Key documentation should include:

• Notes of welfare and absence meetings
• Adjustments discussed or trialled
• OH recommendations and actions taken
• Clear reasons behind decisions
• Follow-up reviews

Proper documentation isn’t about “catching people out”; it protects both the employee and the employer.

What Employers Should Be Doing Now

To handle mental health safely and confidently, organisations should ensure:

Managers are trained
They should know how to spot concerns, start conversations and follow the right steps.

Occupational Health is used early
It removes guesswork and strengthens decision-making.

Policies allow flexibility
Especially where conditions may fall under the Equality Act.

Mental and physical health are treated consistently
Unequal treatment is one of the fastest triggers for claims.

Key conversations are recorded
Not to be heavy-handed, but to ensure fairness and clarity.

Final Thoughts: Getting Ahead of the Problem

Mental health at work is about supporting people emotionally and protecting them legally. Employers who understand this dual responsibility make better decisions, handle cases with confidence and build cultures where people feel genuinely safe to speak up.

If your managers need guidance, or if you’re dealing with a complex mental-health-related absence, MAD-HR can support you each step of the way. We help organisations balance compassion with compliance, a combination that benefits everyone.
