The hidden cost of presenteeism: the £24bn problem you can’t see
Poor mental health costs UK employers around £51bn a year, and presenteeism is the single largest part of it. This guide for HR and people leaders covers what presenteeism really is, why it costs more than absence, and how building resilience reduces it.

The rest of the guide covers why presenteeism costs more than the absence it hides, how to recognise it in your organisation, and the four things that build the resilience that reduces it. One-off, you won’t need to do this again on this device.
What presenteeism actually is, and why it costs more than absence
Absence is the cost you can see. Presenteeism is the bigger one you can’t. It is the productivity that quietly leaks away when people are at work but not able to do their best work, and almost none of it lands on a report.
The cost you can see
Absence is measured. It is logged, reported and managed. When someone is off, you know about it, you can plan around it, and it shows up as a line on a dashboard. That visibility is exactly why absence gets the attention. It is the part of the problem your systems are built to count.
The cost you can’t
Presenteeism is people turning up and working while unwell, depleted or distracted, and performing well below their capacity. It never appears on an absence report, so it is rarely managed. The person is present and counted as working. The lost capacity is real, but invisible.
Presenteeism accounts for around 1.5 times as much lost working time as absence, and it costs more because it is concentrated among higher-paid staff. Centre for Mental Health
A falling absence rate can mean people are recovering. It can also mean they are pushing through instead of taking the time they need. The number looks good either way. Presenteeism is not the same as burnout: burnout is a state of exhaustion, while presenteeism is the behaviour of working on regardless, whatever the cause. It can come from a heavy cold, caring responsibilities, anxiety or grief, long before anything reaches burnout.
How presenteeism shows up in your organisation
You will not find presenteeism in a symptom checklist. It is an organisation-level pattern, and it tends to be clearest in the places your standard reporting does not look.
What it looks like day to day
People logging on while signed off sick. Output drifting down while attendance stays full. Team members online early and late in hybrid roles, where being always available reads as commitment. Meetings attended but decisions slow, errors creeping in, and the same work taking longer than it used to. Attendance is steady. Performance is quietly slipping.
Why your dashboard misses it
Your systems count days lost, not capacity lost. The clearest single signal is low absence and low engagement appearing together, and most reporting never puts those two numbers side by side. If absence is down but engagement, energy and quality are also down, you are very likely paying for presenteeism rather than benefiting from a healthy team.
Four ways to build the resilience that reduces presenteeism
Presenteeism is a capacity problem, not an attendance problem. Attendance policies just move the cost around. These four levers build the capacity and the conditions that let people perform when they are present, and recover when they need to.
Build resilience skills across the whole workforce
Resilience is the capacity to adapt to pressure, recover from setbacks and sustain energy over time. It is a set of practical skills, and it can be taught. When people have those skills, being present is far more likely to mean being able to perform.
- Make it whole-workforce, not just managers. Presenteeism happens at every level, so the capability needs to as well.
- Keep it practical. Tools people can use this week beat abstract models they forget by Friday.
Make stepping back legitimate
People push through when they believe stepping back will count against them. The fix is permission, made real by behaviour rather than policy. When recovery is genuinely allowed, you get less hidden underperformance and faster return to full capacity.
- Managers set the example. If leaders work through illness and leave, everyone else learns that is the expectation.
- Make it safe to flag overload early, before it becomes a problem that needs time off to fix.
Change what managers reward
Presenteeism is often the rational response to what gets noticed. If hours and visible availability are what earn approval, people will supply them even when they are running on empty. Reward the things that actually matter instead.
- Recognise output and recovery, not hours logged and lights left on.
- Watch for the warning sign of full attendance with falling output. That gap is presenteeism in plain sight.
Track capacity, not just attendance
You cannot manage what you do not measure, and right now most organisations only measure the cheaper half of the problem. Putting capacity signals next to attendance data is how the hidden cost becomes visible enough to act on.
- Pair absence data with engagement and wellbeing signals, segmented by team and manager.
- Treat low absence with low engagement as a flag to investigate, not a result to celebrate.
Q3 is usually quieter, which makes it the right window to build resilience across the workforce. Put the capability in place now and it is ready for the autumn workload and the winter illness season, rather than scrambling to respond once people are already running on empty.
Build resilience across your whole workforce
Our Resilience training gives your people practical tools to handle pressure, recover from setbacks and sustain their energy, so being present means being able to perform. The attendance was never the problem. The capacity is.
