Think a doctor’s note means someone is ready to work?

That is one assumption that costs companies more than any other safety assumption. Someone gets hurt. They are gone for six weeks. They return with a piece of paper that reads “OK to return to work”….and they walk out onto the floor.

Two weeks later, they are hurt again.

Here’s the problem:

For most employers, medical clearance is a checkbox. It shouldn’t be. Medical clearance is a determination about whether one individual can safely do one particular job. It’s a legal decision. It’s a financial decision. It has real human consequences.

The good news?

Almost every error can be corrected. And most corrections are free.

Why Medical Clearance Goes Wrong So Often

The numbers do most of the talking here. According to reporting from employers, there were 2.5 million nonfatal workplace injuries and illnesses in 2024. In 2023, 946,500 cases involved days away from work.

Every single one of those workers eventually came back.

That is when the problems begin. No one person owns the decision. HR thinks the clinic processed it. The clinic thinks the supervisor knows the job. The supervisor thinks HR verified paperwork.

That’s where a return to duty evaluation comes in. It fills that void. It addresses the question a doctor’s note can’t: can this employee perform this job, right now, without putting themselves or others at risk? A thorough employee return to duty review will measure a worker’s medical limitations against the actual physical demands of the job — lifting, climbing, respirator use, heat exposure, hours spent driving.

That comparison is exactly why the exercise exists. Eliminate it and clearance becomes a stab in the dark with your signature on it.

The 6 Biggest Fitness For Work Mistakes

They reappear, year after year, in the same organisations. See how many you recognise.

Treating A Doctor’s Note As A Clearance

A treating physician knows the patient. They usually don’t know the job.

They’ve never seen the loading dock. They don’t know he spends four hours a day wearing a full-face respirator, or how much weight he hoists up that ladder – 60 pounds twice an hour. So they write “light duty for two weeks” and leave it to others to figure out what that means.

Vague notes create three problems:

• Supervisors guess at what “light duty” actually means
• Workers get placed into tasks that still injure them
• Nobody has a record of who decided what, or why

Clearance should be written to the job description. Not against some generalized version of rest.

Ignoring What The Job Actually Demands

Try asking employers to write a physical demand job description. See what happens.

They can’t produce one.

You can’t ask a clinician on the planet Earth to make an informed decision without that form. Document job demands: write down weights, distances, postures, exposures, equipment, length of shift. Takes you an afternoon per position and eliminates nearly ALL of the guessing game.

Asking For Too Much Medical Information

This one gets expensive quickly.

Medical exams and inquiries must be job related and consistent with business necessity under the ADA. By sending a general release to a clinic and asking for the entire file, employers are exceeding that boundary. The EEOC has sued employers specifically for this behavior, including where family medical history was obtained as part of a fitness-for-duty exam.

The rule is simple: ask only for what the job requires. Nothing extra.

Rushing People Back Before They’re Ready

The need to cover a shift is urgent. The consequences of re-injury are costly.

A worker who returns too soon is often coming back weakened and sluggish. They start cheating with sloppy form to get through their shift. That’s how an acute back becomes a chronic back. The second injury will cost exponentially more than the first – longer recovery time, larger claim, more time lost.

Keeping People Out Longer Than They Need To Be

The opposite mistake is just as common, and it’s rarely talked about.

In the absence of defined processes, risk-adverse managers bench folks “just to be safe”. That kills payroll, kills morale, and silently communicates to the rest of the organization that nobody has any idea what they’re doing.

Clear criteria solve both problems at once.

Running The Whole Thing On Memory

No forms. No file. No dates.

Then someone disputes a claim, or an inspector begins asking questions, and there is no way to document that the decision ever occurred. Documentation isn’t bureaucracy in this case – it’s the only evidence that the decision was ever made correctly.

What A Solid Process Looks Like In Practice

Successful programmes all have certain features in common. None of them are complex. None of them need lots of money.

Begin with the job, not the person. Each safety sensitive position should have a written physical demands profile in a file cabinet well before anyone becomes injured. Create it once, use it for decades.

Choose an experienced occupational health provider. Occupational medicine clinicians focus on work capacity, not just recovery. That distinction is crucial when the question is whether someone can safely don a respirator or drive a forklift.

Maintain the medical file separately. Health data remains with the provider. The supervisor only sees restrictions/capabilities, nothing else. This safeguards both the employee’s privacy and the company.

Use plain language for your restrictions. “Do not lift objects greater than 20 pounds, reach overhead, re-eval in 14 days” is fine. “Light duty” is not fine.

Schedule a review date. Each restriction should have an expiration and a planned check-in date so temporary restrictions don’t silently become permanent fixtures.

Train the supervisors. They are the ones enforcing restrictions on the floor. If they do not understand the paperwork, the paperwork is worthless.

Getting Clearance Decisions Right

Fitness for work is NOT a favour or an administrative hoop to jump through. It’s a safety control just like a machine guard or lockout procedure.

The good news is that most companies have all the puzzle pieces. They employ injured workers returning to work. They have job descriptions somewhere. They already have a clinic that they use. What most are missing is a written process that links all three together.

To quickly recap:

• Write down what each job physically demands
• Send those demands to the provider, not just the worker
• Ask only for job-related medical information
• Get restrictions back in specific, plain language
• Document every decision and set a review date

Do this and the guesswork is eliminated. Employees return home safe, claims are shortened and no one is left trying to decipher handwriting in the middle of their shift wishing they had asked.
