My condition is not obvious – can it still count under the Equality Act?

Hidden disabilities and long-term conditions often fly under the radar in workplaces, leading many employees to wonder: Does my health condition count under the Equality Act 2010 if it’s not obvious? The short answer is yes – the law recognises a broad range of disabilities, including those that disclosing disability to employer are invisible. But how this applies at work ties closely with another important aspect: stress as a health and safety hazard, and what your employer is legally required to do.

Understanding hidden disability work and the Equality Act 2010

The Equality Act 2010 defines disability very broadly. It doesn’t just mean visible physical impairments. The law says a person is disabled if they have:

a physical or mental impairment
which has a substantial and long-term adverse effect on their ability to carry out normal day-to-day activities

“Long-term” means the impairment has lasted, or is expected to last, at least 12 months. “Substantial” means more than minor or trivial impact.

Crucially, this includes many hidden disabilities and long-term health conditions, such as diabetes, epilepsy, certain mental health conditions, chronic fatigue syndrome, and more. So even if your condition is not immediately visible, it can absolutely fall under the Act’s protection.

Examples of hidden disabilities covered by the Equality Act

Autism spectrum conditions
Chronic pain and fatigue conditions (e.g. fibromyalgia, ME/CFS)
Diabetes
Epilepsy
Hearing or visual impairments not readily noticeable
Mental health conditions causing lasting effects, such as anxiety or depression

Employers are legally prohibited from discriminating against you because of these conditions. They must also make reasonable adjustments to help you perform your role.

Stress as a health and safety hazard at work

Stress isn’t just “in your head” or a personal failing. The Health and Safety Executive (HSE) recognises workplace stress as a significant health and safety hazard, directly impacting both wellbeing and capacity to work.

Under the Health and Safety at Work etc. Act 1974 and associated regulations, employers have a legal duty to manage work-related stress risks so far as is reasonably practicable.

Why stress matters for hidden disability work

Stress and mental health problems often underpin or exacerbate hidden disabilities. Ignoring work-related stress can worsen conditions and create discriminatory barriers.

For example, someone with an invisible condition like anxiety, ADHD, or a chronic illness may find stressful work environments worsen their symptoms and impair their normal day-to-day functioning – ticking the “disability” box under the Equality Act.

The HSE stress risk assessments: What employers must do

The HSE provides a stress risk assessment framework employers can use to identify and reduce workplace stress hazards. This formal risk assessment is a legal part of managing health and safety.

To be effective, a stress risk assessment should:

Identify pressure points in the workplace causing excessive stress
Assess the likelihood and severity of harm to employees
Implement changes to reduce or remove stressors where possible
Monitor the effectiveness of those changes over time

Key pressure points according to HSE Management Standards

The HSE’s Management Standards for work-related stress provide a benchmark to spot stress hazards:

Demands: workload, work patterns, environment
Control: how much say the employee has in their work
Support: encouragement, resources, and support from colleagues and managers
Relationships: workplace conflict, harassment, or bullying
Role: clarity of job role and lack of conflicting demands
Change: how organisational change is managed and communicated

Employers using these standards properly are not just ticking a box; they are helping to prevent mental health deterioration that may constitute or aggravate a disability.

What are my employer’s duties if I have a hidden disability?

Under the Equality Act 2010 and HSE health and safety at work act 1974 guidelines, your employer must:

Not discriminate against you because of your disability, whether visible or hidden
Make reasonable adjustments to remove barriers caused by your disability
Conduct stress risk assessments that consider the impact on disabled employees
Manage and reduce work-related stress hazards
Engage with you to understand your needs and adapt your role or working conditions

If your employer claims “I don’t see your disability, so I don’t have to do anything”, that is not compliant with the Equality Act 2010.

Examples of reasonable adjustments for hidden disabilities

Flexible working hours or remote work options
Allowing extra breaks or reduced workload during flare-ups
Clearer communication and written instructions
Provision of assistive technologies or quiet workspaces
Phased return-to-work plans after absence

What if my employer doesn’t recognise hidden disabilities and stress risks?

Many small employers—like creative studios, cafes, venues, or micro-agencies without formal HR teams—may be unsure or not proactive. But under UK law, your employer cannot simply “ignore” these obligations.

If you face unfair treatment or your employer fails to assess and manage stress risks, you can:

Raise the issue with your line manager in a clear, factual, and constructive way (see our checklist below)
Check your company’s health and safety policy and whether stress risk assessments have been carried out
Request a workplace adjustment or an occupational health referral
Seek advice from a union, ACAS, or employment rights organisations
Consider making a disability discrimination claim if informal steps fail

Checklist: What to email your manager about hidden disability work and stress concerns

Explicitly state your condition and how it affects your work (without needing medical jargon)
Reference your rights under the Equality Act 2010
Explain the impact of workplace stressors on your health
Request a stress risk assessment or reasonable adjustments
Offer suggestions or examples of helpful adjustments
Ask for confirmation of what support the company can provide

Summary: Why your hidden condition counts — and what happens next

The Equality Act 2010 protects a broad spectrum of disabilities, including hidden and non-obvious conditions. It’s not about meeting a specific visible criterion, but about how your health condition impacts your day-to-day activities over the long term.

Workplace stress is a recognised health and safety hazard, and employers must identify, assess, and manage these risks according to HSE guidelines. This helps protect disabled employees and benefits overall wellbeing.

If you have a hidden disability or long-term condition affecting your work, remember you have legal rights, including reasonable adjustments and protection from discrimination.
