Fitness for Work: The Conversation NZ Workplaces Keep Avoiding

We talk a lot about hazards, controls, and “reasonably practicable” steps. But we rarely talk about the thing that quietly shapes risk every single day: Whether a person is actually fit to do the job they’re being paid to do.

Not just “fit” as in gym membership. Fit as in: capable, healthy enough, physically and mentally able, and not putting themselves or others at risk.

Fitness for work looks very different depending on the role.

Sedentary, Physical, and Safety‑Sensitive Roles Are Not the Same

Sedentary roles (office, admin, desk-based)

Risks are slower, quieter, and cumulative:

• Musculoskeletal strain
• Poor posture
• Low movement
• Fatigue
• Stress and cognitive overload

People can be “fine” for years – until they’re not. Sedentary work hides harm behind routine.

Physical roles (warehousing, trades, manufacturing, logistics)

These roles demand:

• Strength
• Endurance
• Mobility
• Balance
• Cardiovascular capacity

If someone’s fitness drops, the risk doesn’t just increase – it compounds. Lifting, twisting, climbing, carrying… these tasks punish the body if it’s not ready.

High‑risk / safety‑sensitive roles (driving, machinery, heights, confined spaces)

Here, fitness isn’t optional. It’s a critical risk control. Fatigue, reduced mobility, untreated health conditions, medication side effects, or reduced strength can mean:

• Slower reaction times
• Poorer decision-making
• Reduced hazard perception
• Increased likelihood of catastrophic events

This is where “she’ll be right” becomes “someone gets seriously hurt”.

Employers Have Due Diligence BEFORE They Hire

Under HSWA, a PCBU must ensure workers are capable of performing the role safely. That means before hiring, employers should:

• Define the inherent physical and cognitive demands of the role
• Conduct pre-employment functional assessments for physical or safety-sensitive work
• Check for role-specific risks (e.g., working at heights, respirator use, shift work)
• Ensure the job description reflects real work, not a sanitised HR version
• Be honest about the demands – no sugar-coating to fill vacancies

Hiring someone who cannot safely perform the role is not kindness. It’s negligence.

Workers Also Have Responsibilities – Real Ones

Workers aren’t passive recipients of safety. They have duties too:

• Maintain their own health and fitness to meet the demands of the role
• Seek medical advice when something changes
• Use controls properly (equipment, PPE, mechanical aids)
• Disclose changes that affect their ability to work safely

This isn’t about blame. It’s about partnership. A worker who hides a condition because they fear judgment or job loss is a worker at risk – and a symptom of a culture problem.

When Should a Worker Disclose That Something Has Changed?

The moment a change affects:

• Strength
• Mobility
• Pain levels
• Fatigue
• Medication
• Vision or hearing
• Mental health
• Ability to concentrate
• Ability to perform critical tasks

Disclosure isn’t about punishment. It’s about early intervention. The earlier the conversation, the more options exist: modified duties, temporary adjustments, medical review, or rehabilitation.

How Should Employers Approach This Topic?

With respect, clarity, and zero judgment. The worst approach is: “You’re not fit enough – fix it.”

The best approach is: “We want you to be safe and well. Let’s talk about what the role requires and how we can support you to meet those requirements.”

Employers should:

• Normalise fitness-for-work conversations
• Train leaders to have them well
• Focus on capability, not body size
• Use objective assessments, not opinions
• Create psychological safety so workers speak up early
• Avoid assumptions – especially about weight, age, or appearance

Fitness for work is a risk conversation, not a personal critique.

Perception vs Reality: The “She’ll Be Right” Trap

Perception: “She’s been doing it for years – she’ll be right.”

Reality: “She’s been hurting herself every day for years – and today might be the day something gives.”

Perception: “He’s strong enough.”

Reality: “He’s compensating for reduced mobility and one wrong move will take him out for months.”

Perception: “They’ve never had an incident.”

Reality: “Nothing has happened yet – but the risk indicators are flashing.”

Past luck is not a control. Familiarity is not a control. Confidence is not a control.

How to Manage Fitness-for-Work Risks Properly

For Employers

• Conduct task analysis and define physical/cognitive demands
• Use pre-employment and periodic functional assessments
• Provide training on safe movement and body mechanics
• Design work to reduce unnecessary strain
• Rotate tasks to avoid overuse injuries
• Encourage early reporting
• Build a culture where health conversations are normal

For Workers

• Maintain personal health and fitness
• Seek medical advice early
• Use equipment and controls properly
• Report changes in capability
• Engage in rehabilitation plans
• Understand the demands of the role and prepare accordingly

For Both

• Treat fitness for work as a shared responsibility
• Focus on capability, not blame
• Keep conversations grounded in risk, not assumptions
• Review roles regularly – work changes, bodies change, risks change

Managing the risk

Fitness for work isn’t about weight. It’s not about judging bodies. It’s not about policing health.

It’s about risk. It’s about capability. It’s about honesty. It’s about protecting people from harm – including harm they’ve normalised.

If we want safer workplaces in New Zealand, we need to stop avoiding the conversation and start having it well.
