When Crews Stop Wearing Vests: A Sign You Missed Something Upstream

Key Takeaway

Crews don't remove vests without a reason. In most cases, the issue traces back to fit, heat, or workwear that doesn't match the job. OSHA places responsibility on employers to assess hazards and select PPE that workers can actually wear. When you fix those upstream decisions, compliance improves and safety follows.

Why Do Workers Stop Wearing High-Visibility Vests on the Job?

Most supervisors have seen the pattern. A vest comes off in the heat, gets unzipped near moving equipment, or ends up tossed in a truck before the shift is over. From a distance, that can look like defiance. Up close, it usually points to friction between the worker, the task, and the apparel itself.

Worker feedback is consistent on one issue in particular. PPE that traps heat often leads to discomfort, fatigue, and reduced performance on the job, which makes workers more likely to loosen it, adjust it, or take it off during the shift.

It’s rarely about workers not caring. The real issue is what makes the vest hard to keep on during the work. In most cases, that friction shows up in a few predictable ways, heat, fit, and how workers view the decisions behind the gear.

How Does Heat Stress Lead to PPE Noncompliance?

Heat is a major factor that can undermine PPE compliance on a job site. When a vest traps heat and limits airflow, even routine tasks can feel harder, slower, and more exhausting.

NIOSH’s guidance on PPE heat burden states that certain types of PPE and clothing can increase the risk of heat-related illness. OSHA makes the same point in its Heat Stress guide and its heat exposure overview, both of which note that protective clothing can reduce the body’s ability to cool itself. When a worker pulls off a vest in July, that may be less about rejecting the rule and more about reacting to heat strain that was never addressed.

How Does Poor Fit Affect Safety, Movement, and PPE Use?

Fit affects more than comfort. It shapes how people move, how long they can tolerate the gear, and whether they keep it on for the full task. When PPE does not fit properly, workers often spend the day adjusting it, working around it, or removing it altogether.

This is a widespread issue, not an isolated complaint. Research shows that 14% of workers do not wear PPE because it does not fit properly. The problem is even more pronounced for women in the trades, where 88% report difficulty finding PPE that fits correctly and 77% say poor-fitting PPE has created hazards on the job.

OSHA notes in its PPE overview that equipment should fit comfortably because comfort directly affects worker use. When fit is off, the impact shows up quickly:

• Movement feels restricted
• Workers tire out faster
• Tasks become harder to complete

In the field, those issues are hard to ignore. A vest that rides up under a harness, blocks access to tools, catches on controls, or traps heat at the neck becomes a constant distraction. Workers don’t usually explain it in those terms. They just stop wearing it.

How Does Trust in Leadership Impact PPE Compliance?

Workers notice what gets purchased and why. They know when the company chose the lowest-cost option, and they know when complaints disappear without a response.

That’s why trust matters. OSHA guidance reinforces that workers need to be part of the process and trust the decisions behind it:

• OSHA’s Worker Participation guidance states that workers should help establish, operate, evaluate, and improve the safety and health program
• OSHA’s Management Leadership guidance states that leadership must provide resources and consider safety in purchasing decisions
• OSHA’s Safety and Health Program Management Guidelines state that workers should be able to raise concerns without fear of retaliation

When that feedback loop breaks down, compliance often drops with it. In some cases, taking off the vest is not just a comfort issue. It is often the clearest sign that the current gear is not working for the job.

Once that trust starts to slip, the issue becomes harder to ignore. The next step is figuring out where things broke down in the first place.

What Should Supervisors Review When Workers Stop Wearing Vests?

Start with the work, not the rulebook. Look at when and where the vest comes off, then connect it to the task. Does it happen during the hottest part of the day, or when workers climb, reach, or handle materials?

Patterns matter here. If one crew struggles more than another, or one vest type gets removed more often, that points to a specific issue, not random behavior.

Once you see the pattern, go back to the basics. OSHA requires employers to assess workplace hazards and select PPE that fits each worker under 29 CFR 1910.132(d). In construction, 29 CFR 1926.95 requires employers to provide PPE and ensure it fits properly.

That review should focus on how the work and the apparel interact:

• Whether the vest matches the actual hazard
• Whether the vest’s design and fit work with the task
• Whether airflow is sufficient for the season
• Whether the apparel works with harnesses, tools, radios, and layers
• Whether workers had input in the selection
• Whether training covered real-world use and limitations

When you step back and look at the full picture, a vest issue rarely stands alone. It usually points to a gap in how the workwear was selected, tested, or adjusted for the job. The fix often comes down to one thing, choosing workwear that actually matches the job.

How Does Kishigo Workwear Improve PPE Compliance and Wearability?

The right question isn’t “Why won’t they wear it?” The better question is, “What did we miss before we handed it out?”

When you look upstream, the pattern becomes clear. Crews remove vests when the apparel works against them. Heat builds up. Comfort suffers. Movement feels restricted. Fit gets in the way. Over time, that friction leads to noncompliance.

Kishigo designs high-visibility workwear to remove that friction.

With more than 50 years of experience, Kishigo focuses on how apparel performs in real job conditions, not just how it looks on a spec sheet. Their workwear supports comfort, movement, and durability, so crews can wear it through a full shift without fighting it.

Here is how Kishigo helps solve the root causes behind vest non-use:

• Comfort that holds up in the field: Breathable mesh panels improve airflow and help reduce heat buildup during long, hot shifts.
• Fit that stays in place: Thoughtful sizing and design support proper fit, helping meet OSHA expectations while improving day-to-day wearability. Kishigo also offers womenswear specifically designed to fit a woman’s shape, improving comfort, mobility, and overall performance on the job.
• Freedom to move on the job: Ergonomic cuts and functional pocket placement reduce interference with tools, harnesses, and active work.
• Built for daily wear: Reinforced stress points and durable construction hold up under real job conditions, building trust with crews.
• Details workers notice: Features like padded collars and practical storage improve comfort and function in ways that matter on site.

When workwear fits the job, workers stop looking for reasons to take it off. Supervisors spend less time enforcing rules and more time managing the work.

Kishigo makes workwear that workers actually want to wear. If your crews keep removing their vests, take a closer look at what you are asking them to use.

FAQ

Why do workers remove high-visibility vests on the job?

Workers often remove vests due to heat buildup, poor fit, restricted movement, or discomfort during tasks. Research shows discomfort and poor fit are leading causes of PPE non-use, which signals a problem with selection and job conditions, not just worker behavior.

How does heat affect PPE compliance on job sites?

Heat increases physical strain and can make high-visibility apparel uncomfortable to wear for long periods. NIOSH and OSHA both note that protective clothing can limit the body’s ability to cool itself, which can lead workers to remove vests to manage heat stress.

What does OSHA require for PPE fit and selection?

OSHA requires employers to assess workplace hazards, select appropriate PPE, and ensure it properly fits each worker. In construction, employers must also provide PPE at no cost and maintain it in a safe and reliable condition, which makes fit and selection a management responsibility.

How can supervisors improve PPE compliance without strict enforcement?

Supervisors can improve compliance by reviewing job conditions, gathering worker feedback, and selecting workwear that matches the task and environment. When PPE fits well, allows movement, and reduces heat stress, workers are more likely to wear it consistently.

What features should you look for in high-visibility workwear?

Look for breathable materials, proper sizing, ergonomic design, and durable construction. Features like mesh panels, reinforced stress points, and functional pockets improve comfort and usability, which helps workers keep their apparel on throughout the shift.

Why does women’s high-visibility workwear need a proper fit?

Women’s workwear should fit the worker, not force the worker to adapt to oversized or poorly shaped gear. Properly fitted women’s high-visibility apparel improves comfort, mobility, and safety while helping meet OSHA expectations that PPE fits each affected employee.
