Why Working While Sick Hurts You — and Your Employer

Why Working While Sick Hurts You — and Your Employer

Introduction

You wake up with a pounding headache, a scratchy throat, and a fever. Your body says stay in bed, but your mind whispers, you should log in or show up anyway. This pressure to work through illness — known as presenteeism — is more common than you might think, and it’s harming both workers and businesses.

At Employment Matters, we often see the impact workplace culture has on health and productivity. The truth is simple: working while unwell rarely benefits anyone in the long run.


What Is Presenteeism?

Presenteeism happens when employees keep working despite being too ill to perform at their best — whether that’s in the office or remotely. While absenteeism (taking sick leave) is easy to measure, presenteeism often flies under the radar. But research shows it can cost economies almost twice as much as absenteeism, thanks to reduced productivity, more mistakes, and longer recovery times.


Why Workers Push Themselves While Sick

Several factors can lead people to work through illness:

  • Limited sick leave: In Ireland, employees are entitled to five statutory paid sick days per year (as of 2025). Once those days are used, many workers can’t afford unpaid time off.
  • Company culture: Some organisations discourage sick leave — openly or subtly — by praising “toughing it out” or leaving roles understaffed.
  • Job security worries: Employees who feel their position is at risk may avoid calling in sick, fearing it will hurt their career prospects.
  • Personal drive: High achievers or workaholics may feel guilty stepping away, even when it’s necessary for their health.

The Hidden Costs of Working While Sick

Choosing to work instead of rest doesn’t just slow recovery — it can also:

  • Spread illness to colleagues (in the office)
  • Increase the likelihood of burnout
  • Reduce focus and decision-making ability
  • Lead to costly mistakes
  • Create a culture where overwork is expected, not the exception

The Remote Work Myth

Some assume remote workers can “push through” sickness without consequences. While remote work does eliminate the risk of spreading germs, the mental and physical toll of working while ill remains. Remote employees may still face monitoring, deadlines, and performance expectations — all of which can pressure them to work when they should be resting.


Why Rest Is the Smarter Choice

For both employers and employees, allowing proper recovery benefits everyone:

  • Faster return to full productivity
  • Lower risk of long-term health issues
  • Stronger team morale when rest is encouraged and respected
  • Fewer costly mistakes caused by fatigue and poor concentration

Key Takeaway

Presenteeism is not a sign of dedication — it’s a warning sign of poor workplace health culture. Whether you’re an employer or employee, it’s time to move away from the “always-on” mindset and make space for recovery.
