Presenteeism: The Productivity Drain You're Not Measuring
Absenteeism is easy to count - someone isn't there. Presenteeism is harder and usually bigger: the employee is present but impaired, working at a fraction of their capacity because of an untreated condition. Research consistently finds presenteeism costs employers more than absenteeism, precisely because it's invisible.
What it looks like
The high performer whose output quietly halves. The manager who can't concentrate through meetings. The employee taking twice as long on everything and hiding it. None of it shows up as a sick day, so none of it shows up in your reporting - but all of it shows up in your results.
Why mental health is the biggest driver
Depression, anxiety, and ADHD directly degrade concentration, decision-making, and energy - the raw materials of knowledge work. An employee doesn't need to be absent to be operating at 50%. And because they're still showing up, no one intervenes.
What reduces it
Treatment. When the underlying condition is actually treated, capacity returns. That's why presenteeism is one of the strongest arguments for the medical layer: it's a huge, hidden cost that only real care - not awareness - reduces. Start measuring it, even roughly, and the business case for treatment writes itself.
CorpCARE targets the treatable conditions behind presenteeism - recovering capacity you can't currently see or count.
