Illness Is Not Misconduct: Multiple Sclerosis in the Workplace

For many people living with multiple sclerosis, work is about far more than an income.

It can mean independence, purpose, identity, connection, confidence and the ability to contribute meaningfully to family and society.

Yet MS can bring workplace challenges that are often misunderstood. A person may look completely well while dealing with severe fatigue, cognitive overload, pain, mobility changes, vision difficulties, bladder urgency, heat sensitivity or the after-effects of treatment.

This is why illness in the workplace cannot be managed through assumptions.

MS does not automatically mean incapacity

A diagnosis of MS does not mean that someone cannot work, cannot grow in their career or cannot continue to be a valuable employee.

Many people living with MS remain highly skilled and productive for years. Some need no workplace adjustments at all. Others may need support at particular times, such as during a relapse, after treatment, while managing fatigue, or when symptoms change.

The important question is not:

“Can this person still do their job?”

It is:

“What practical support, if any, would help this person continue doing their job well?”

Invisible symptoms can have a real workplace impact

MS symptoms vary greatly from one person to another and can fluctuate from day to day.

An employee may be managing:

  • severe fatigue that is not relieved by sleep;
  • slower processing, memory difficulties or trouble concentrating;
  • mobility, balance or coordination challenges;
  • pain, numbness, weakness or spasticity;
  • vision changes;
  • heat sensitivity;
  • bladder urgency;
  • anxiety, stress or low mood;
  • medical appointments, MRI scans, infusions or rehabilitation.

These symptoms are not always visible. They can also be misunderstood as a lack of motivation, poor attitude, unreliability or poor performance.

That misunderstanding can be deeply damaging.

Early communication can prevent a crisis

People living with MS may be reluctant to disclose their diagnosis at work. They may fear discrimination, being passed over for promotion, being viewed as unreliable or losing their job.

Employers and managers may also feel uncertain. They may not know what they are entitled to ask, what information they need, or how to respond if an employee’s health affects attendance or performance.

When nobody talks openly and respectfully, the situation can become more difficult than it needs to be.

Early communication allows the employee and employer to identify practical support before sick leave is exhausted, performance concerns escalate or the employee’s health deteriorates.

An employee does not have to disclose every medical detail. They can focus on what affects their work and what support may help.

For example:

“I live with a chronic neurological condition which can sometimes affect my energy, mobility and concentration. I would like to discuss practical adjustments that will help me continue doing my work effectively.”

Reasonable accommodation is not special treatment

South African employment law protects employees against unfair discrimination on the basis of disability. Employers have a responsibility to consider reasonable accommodation where this is needed and does not create unjustifiable hardship.

Reasonable accommodation does not mean lowering standards or giving someone an unfair advantage.

It means removing unnecessary barriers so that an employee can perform the essential requirements of their job.

For a person living with MS, practical adjustments may include:

  • flexible start and finish times;
  • hybrid or remote work where the role allows it;
  • rest breaks or a quieter workspace;
  • reduced unnecessary travel;
  • a cooler workstation or protection from heat;
  • accessible parking and easy access to toilets;
  • written instructions, task lists or meeting notes;
  • screen magnification, adjusted lighting or larger monitors;
  • time off for treatment, infusions, scans or specialist appointments;
  • temporary adjusted duties after a relapse or hospital admission;
  • a phased return to work.

The right adjustment depends on the person, their symptoms and the nature of their role.

When illness is mistaken for misconduct or poor performance

When an employee is repeatedly absent, visibly struggling or unable to perform at their usual level, employers may instinctively move towards performance management or disciplinary action.

But where MS or another health condition may be involved, this can be the wrong route.

Before treating a problem as misconduct or poor performance, employers should consider whether illness, fatigue, cognitive changes, relapse symptoms, treatment effects or emotional strain may be contributing.

A fair process should include a respectful conversation, clarification of the essential requirements of the job, consideration of reasonable adjustments and, where needed, occupational-health input.

The aim should be to help the employee remain in meaningful work wherever reasonably possible.

Confidentiality matters

An employee’s diagnosis and medical information are private.

An employer may need to understand whether the employee is fit to work, whether adjustments are needed and whether there are restrictions or safety concerns. They do not usually need unnecessary clinical detail.

Occupational-health practitioners can play an important role by assessing fitness for work, recommending adjustments and helping to communicate appropriately between the employee, treating doctor and employer.

A shared responsibility

Employees living with MS can help by speaking up when support is needed, keeping relevant medical records, understanding workplace policies and focusing discussions on practical solutions.

Employers can help by creating a culture where employees feel safe to disclose health concerns, training managers to respond appropriately, protecting confidentiality and considering accommodation before making assumptions.

A supportive workplace is not only fair and legally safer. It retains skills, experience and dignity.

MSSA Workplace Matters

Multiple Sclerosis South Africa supports people living with MS to better understand the practical challenges that can arise at work.

We can help members think through workplace conversations, identify MS-related challenges that may need to be explained, and access useful information and resources.

MSSA does not provide legal representation or replace medical, occupational-health or labour-law advice. Every workplace situation is different, and individual professional guidance may be needed.

MS is not a measure of a person’s ability, commitment or value at work. With understanding, early communication and appropriate support, many people living with MS can continue to build meaningful and sustainable careers.
