What Happens When Companies Treat Sleep Like a Business Metric
A handful of companies have tried paying employees to sleep more, building nap infrastructure, or restructuring work hours around circadian biology. Here's what they actually found.

In 2015, Mark Bertolini, then CEO of Aetna, started paying his employees to sleep.
The program was simple: employees who logged at least 20 nights of 7 or more hours of sleep per month — verified through a fitness tracking device — received $25 per qualifying night, up to $500 per year. Bertolini, who had become vocal about mindfulness and wellness after a serious ski injury, framed the program as an investment in workforce performance rather than a benefits add-on.
The numbers Aetna reported two years later: $2,000 per participating employee in estimated annual savings, driven primarily by reduced healthcare costs and improved performance metrics. Turnover among participants dropped 7.5% compared to non-participants. Aetna kept the program running.
The RAND baseline
The Aetna experiment didn’t happen in a vacuum. In 2016, a RAND Corporation research team led by Marco Hafner published an analysis that gave the sleep-as-business-metric argument its most rigorous economic framing.
Their estimate: sleep deprivation costs the US economy $411 billion per year. The methodology aggregated several cost categories — reduced productivity, increased mortality risk, higher healthcare utilization, and accident-related losses — across the working population. The per-worker estimate ranged from $1,200 to $3,100 annually, depending on the severity of sleep deficit and industry.
Germany ($60 billion), Japan ($138 billion), and the UK ($50 billion) showed similar patterns when analyzed with the same methodology. The total estimated cost across the five countries studied was $680 billion annually.
These are headline numbers that come with methodological caveats. Sleep is self-reported; attribution is difficult; the counterfactual (“what would the economy produce if everyone slept 8 hours?”) is speculative. But even half the RAND estimate represents a business problem of a scale that should interest finance departments.
What companies actually do versus what they say
McKinsey’s 2016 article in the McKinsey Quarterly — “Why Sleep Matters” — is a useful case study in the gap between corporate rhetorical commitment to sleep and actual operational change. The article, co-authored by Czeisler and McKinsey consultants, argued for organizational cultures that stop treating sleep deprivation as a performance signal. It was widely shared among senior executives.
The firms that actually restructured work patterns in response to sleep science remain exceptions. Nike built nap rooms at its Beaverton, Oregon headquarters. Ben & Jerry’s installed nap pods for production staff. Zappos briefly offered nap rooms before its acquisition by Amazon.
What most companies implemented instead was softer: wellness programs with sleep tracking integrations, mental health days, and occasional presentations from sleep consultants. The structural changes — reducing meeting load, enforcing schedule predictability for shift workers, eliminating email expectations after 9 PM — happen rarely, because they require managers to give something up rather than offering employees an optional benefit.
The Goldman Sachs data point
In 2021, a group of first-year analysts at Goldman Sachs produced an internal slide deck — which leaked and circulated widely — documenting their working conditions. The survey of 13 analysts found an average workweek of 95 hours, physical health rated at 2.8 out of 10, and mental health at 2.8 out of 10. Several analysts described symptoms consistent with clinical burnout and sleep deprivation.
Goldman’s response included reaffirming the firm’s “Saturday rule” (protecting analysts from required Saturday work) and making some commitments about workload management. Subsequent reporting suggested the changes were modest and inconsistently enforced.
The Goldman case is not a failure of corporate sleep programs — it never had one. It’s an illustration of something more structural: sleep deprivation is embedded in the incentive systems and status signals of certain industries in ways that no wellness benefit can reach. When working 95-hour weeks is treated as a demonstration of commitment, a nap pod in the break room is an ironic gesture.
The honest version of the ROI argument
Here’s the problem with the business case for sleep: it requires attributing diffuse benefits to a specific program, across a long time horizon, in competition with explanations that are easier to measure.
Aetna’s $2,000 per employee estimate is plausible but not independently verified. The counterfactual — what would have happened without the program — isn’t constructed. Participants self-selected into the program, which means motivated employees were overrepresented. The study design wasn’t randomized.
None of this proves the program didn’t work. It proves that the evidence is soft enough that a skeptical CFO has an easy path to rejecting it.
The structural argument is stronger than the ROI argument: if your employees are chronically sleep-deprived, they are making worse decisions, producing lower-quality work, committing more errors, and leaving faster than they would otherwise. You don’t need a program to fix this. You need schedules that make adequate sleep possible, norms that don’t penalize adequate sleep, and managers who don’t send 11 PM emails as a management style.
Programs help at the margins. Culture is the actual variable.
The economics of individual sleep deprivation — what it costs a person rather than a company — are detailed in the cost of sleep deprivation. The social accountability mechanisms that corporate sleep programs try to leverage are examined in the science of social accountability.

That said: a consistent wake time — the thing DontSnooze is designed to enforce — is the single behavioral intervention most likely to produce the regularity that corporate sleep programs are trying to incentivize. The Aetna program paid people for 7 hours. The hours matter less than the consistency.
