The workforce Numbers We Don’t Talk About
Mental health and substance use are already in your workplace.
The data tells a story most organizations are still afraid to read.
Picture a Monday morning standup meeting.
There are ten people in the room.
Statistically, two of them are managing a mental health condition right now.
One has had a drink before noon in the last month to take the edge off.
And the meeting will run the same as it always does, because none of this is visible. None of it is discussed, except maybe in the rumor mill or in hushed conversations between HR and managers around performance review time.
Mental health and substance use disorders affect a staggering share of the working population, and yet they remain among the least-discussed drivers of workplace performance, absenteeism, and turnover.
1 in 5 - U.S. adults experience a mental illness in any given year, or roughly 57 million people (NAMI, 2023)
$1 trillion - Estimated annual global cost to employers from depression and anxiety in lost productivity (WHO, 2019)
$81 Billion - Annual cost to U.S. employers from alcohol misuse alone, including absenteeism, accidents, and turnover (NIAAA, 2015)
Those numbers are large enough to feel abstract to most of us, so let’s break it down to real day-to-day life. Studies estimate the average employee experiencing untreated depression loses about 27 days of productive work per year. They may be physically at work but struggling with presenteeism: showing up while running at a fraction of capacity. It's the meeting where they can't focus. The deadline they quietly missed. The collaboration that quietly frays away at the edges as trust is lost.
Presenteeism has been researched for years with a significant focus on chronic illness. Illnesses get all the “attention,” in this case, because they can often be treated with medical care and thus are “fixable” in the clinical sense. However, newer research from The National Safety Council has shown that mental health and substance related concerns are some of the leading causes of workplace preventable deaths, including one in eleven worker deaths resulting from overdose on the job.
While data shows there are risks and implications to workplaces when employees are struggling, it can’t fully capture the truth of the matter: Most of this doesn’t look like a crisis. Until it does.
70% of people with substance use disorders are employed full time.
Not everyone struggling is in crisis. Most are just quietly managing… and quietly losing ground. Think of it as a spectrum: At one end, someone is having a hard few weeks after a loss. They’re drinking a bit more wine than usual each evening and find it harder to concentrate at work the next day. At the other end, someone is in acute crisis, completely unable to function and maybe regularly missing work. The vast majority of employees, however, are sitting right in the middle. They look like the capable colleague, who is maybe a little behind on their case load. A top performer whose output has dipped inexplicably, but says they’ll get back on track. The office personality who has stopped coming to optional events and started taking Fridays slow.
Substance use concerns also follow the same pattern. The National Survey on Drug Use and Health consistently finds that the majority of people with substance use disorders are employed full time (70%, according to the Substance Abuse and Mental Health Services Administration). They may not be the entry-level employee, or the managing partner holed up in his office with a bottle in the drawer, but they could be. Substance Use Disorder touches every level of the org chart. Most of it is invisible, handled quietly and out of sight, compounding over time.
So what can organizations actually do?
The research points to a few levers that move the needle. Notably, most of them have nothing to do with crisis response.
Early access matters more than late intervention. Employees who can see a therapist within days are dramatically more likely to use that resource than those facing a six-week wait. EAP utilization rates hover around 3–6% at most companies - far below what the data says is needed - and waiting lists are the single most cited barrier.
Manager behavior shapes what people disclose and seek. Studies consistently show that the single strongest predictor of whether an employee seeks help is whether they believe their manager would support them doing so vs penalize them. Training managers to recognize early signs and respond without stigma is among the highest-return investments an organization can make.
Language signals safety. Workplaces that normalize mental health conversations through leadership modeling, communications, and policy often see higher utilization of support resources and lower rates of presenteeism. It's not soft or unprofessional. It’s compassionate, human-centered, and most importantly, it shows up in the numbers.
