Ask someone to picture the modern skills economy and you’ll get coders, data analysts, and freshly minted grads in LinkedIn headshots. The workforce that keeps those offices open almost never makes the frame. That’s a blind spot, both for HR leaders and for anyone paying attention to where real career pathways sit today.

Commercial cleaning has grown into one of the largest skilled-service employers in the country, and the work it does shapes employee health, retention, and productivity inside every office building it touches.

So why does the sector still get treated as invisible?

A Sector Bigger Than Most HR Teams Realize

The scale here isn’t small. According to industry research, the U.S. commercial cleaning market was valued at USD 19.4 billion in 2025 and is projected to grow at a 7.5% CAGR through 2035, with the janitorial services industry employing more than 2.4 million people in 2023.

That’s a workforce larger than many white-collar sectors HR departments spend far more time analyzing. And the skill demands are real: chemical handling, floor care, biohazard protocols, equipment operation, and, more and more, the digital reporting tools facility managers rely on.

The Health Case HR Leaders Keep Underestimating

There’s a direct line between how an office is cleaned and how often its staff calls in sick. Desks, phones, keyboards, and shared kitchen surfaces are dense with bacteria that spread through casual contact.

That’s not an argument for panic. It’s an argument for treating cleaning contracts as part of an employee wellness strategy, not a line-item afterthought.

The knock-on effects land in every metric HR already tracks: absenteeism, presenteeism, morale, and the impression candidates form the moment they walk through the space.

Skilled Work Meets Real Standards

Cleaning gets labeled unskilled labor. The regulations tell a different story. Federal standards on chemical safety, personal protective equipment, and biological hazards apply directly to this workforce.

For example, OSHA guidance confirms that the Bloodborne Pathogens standard applies to contractors cleaning up blood after accidents, triggered by any reasonably anticipated occupational exposure. That’s the kind of compliance training a serious janitorial employer builds into onboarding, and it’s the kind of credential a worker can carry into higher-paying facility roles.

Employers and Facility Teams Have More Skin in This Than They Think

For HR and operations leaders, the takeaway is simple. The people cleaning your building are part of the workforce your employees interact with every day, and the quality of their training shapes the quality of the space you’re asking talent to show up in.

That’s why corporate teams in major metros increasingly vet office cleaning partners on training programs, safety records, and turnover, not price per square foot alone. Apply the same lens you’d use for any staffing partner: what skills do their people bring to the job, and how consistently do they deliver them?

Treat cleaning as a workforce decision, and the payoff shows up where it counts: fewer sick days, better retention, and an office that looks the way your recruiting deck promises it will.
