Most employers monitor sickness absence closely. Fewer people off sick often looks like a sign of a healthy, productive workforce.
But what if the bigger problem isn’t the employees who stay at home?
What if it’s the ones who keep turning up?
Presenteeism – the act of working despite being physically or mentally unwell – is one of the biggest hidden costs facing organisations today. Unlike sickness absence, it’s almost invisible. Attendance records look healthy, yet beneath the surface productivity falls, mistakes increase, morale suffers and employees can become seriously unwell before anyone realises there’s a problem.
Being present isn’t the same as being well.
For many employees, continuing to work while unwell feels like the right thing to do. They don’t want to let colleagues down, workloads are already overwhelming, they’re worried about falling behind or fear being judged for taking time off. Others may be concerned about job security or simply feel uncomfortable talking about their mental health.
While these motivations often come from a place of commitment, the consequences can be significant.
An employee struggling with stress, anxiety, burnout, chronic pain or the effect of medication is unlikely to perform at their best. Concentration drops, decision-making becomes more difficult and errors become more common. In some industries, particularly those involving safety-critical work, the risks extend far beyond reduced productivity.
Ironically, working through illness often delays recovery. What might have been a few days away from work can become weeks or even months of absence because the individual never had the opportunity to properly recover.
The financial impact of presenteeism is substantial. Many studies suggest it costs organisations considerably more than sickness absence itself, simply because it affects far more people and often continues unnoticed for long periods.
The challenge has become even greater with hybrid and remote working.
Employees can appear engaged on video calls while quietly struggling with exhaustion, anxiety or declining mental health. Managers no longer see the subtle changes that might once have prompted a conversation. Instead, the warning signs become digital – late-night emails, unusually long working hours, reduced participation in meetings, slower responses, declining quality of work or someone who never seems to switch off.
None of these signs alone proves someone is struggling. However, when patterns begin to emerge, they should prompt curiosity rather than criticism.
The most effective managers don’t wait until performance becomes a formal issue. They have regular wellbeing conversations, ask open questions and create an environment where employees feel comfortable saying they’re not coping before reaching crisis point.
Creating that culture starts at the top
If leaders openly work through illness, send emails at midnight or celebrate employees who “never take a sick day”, they’re unintentionally sending a powerful message that attendance matters more than wellbeing.
Healthy organisations do the opposite.
They encourage employees to take annual leave, maintain realistic workloads, support flexible working where appropriate and recognise that recovery isn’t a weakness – it’s essential for sustained performance. Employees should never feel they have to choose between protecting their health and protecting their career.
Occupational health also has an important role to play
An early occupational health referral provides independent advice about fitness for work, workplace adjustments, phased returns and the practical support that can help someone remain in work safely. Rather than relying on assumptions, managers are able to make informed decisions that benefit both the employee and the organisation.
Preventing presenteeism isn’t complicated, but it does require intention:
- Train managers to recognise early warning signs.
- Encourage supportive conversations before problems escalate.
- Review workloads regularly.
- Promote healthy boundaries between work and home life.
- Measure wellbeing alongside absence figures instead of relying on attendance alone.
Ultimately, the healthiest workplaces aren’t those where nobody takes sick leave. They’re the workplaces where employees know they can recover when they need to, ask for help without fear and return to work ready to contribute at their best.
When organisations stop measuring success simply by who’s at work and start focusing on whether people are well enough to do their jobs safely and effectively, everyone benefits. Productivity improves, long-term absence reduces, employees stay engaged and businesses become stronger, healthier and more resilient.
