Are Psychosocial Hazards Hiding in Your Evidence?

Psychosocial hazards are workplace conditions that can create stress and affect how people think, communicate, make decisions, and perform their work. When investigators collect evidence after an incident, these conditions can be easy to overlook because they may not leave behind the same visible evidence as a failed component, damaged equipment or a physical hazard.

When investigators collect evidence, they know to look at equipment, task-specific paperwork, the work environment, and witness statements. But investigators often overlook the conditions that influence human performance.

Was the employee working under time pressure?

Were priorities unclear?

Were staffing levels creating excessive workload?

Had changes in the company created uncertainty or confusion?

These are examples of working conditions that may indicate psychosocial hazards exist because they can easily create stress.

Psychosocial Hazards Affect Human Performance

Some think that psychosocial hazards are limited to bullying or micromanaging, but the definition is broader. Psychosocial hazards are sometimes built into how the work is designed, managed, and experienced. Examples include excessive job demands, unclear roles, inadequate support, poor change management, isolation, poor physical environment, job insecurity, and others.

Why does this matter? Because stress can affect attention, memory, communication, and decision-making. When workers spend mental energy navigating psychosocial hazards, they have less energy to recognize hazards and respond safely to unexpected situations.

Look Beyond What The Worker Did

Imagine an employee took a shortcut. You may collect evidence about his training, experience, and the procedure in place. He knew better.

Now widen the lens.

What were the conditions at the time? Not just the physical conditions, but what types of things may be causing stress?

He may have received competing instructions from two supervisors. Maybe workers often take shortcuts because supervisors reward speed instead of quality. Insufficient lighting or noise in the environment may have made it harder for him to focus.

Each piece of information around the conditions that existed at the time will help you understand the employee’s decision to take a shortcut. Without that information, it would be easy to end with the employee’s action.

“The employee took a shortcut” tells you what happened. But it doesn’t tell you much about weaknesses in the work system that allowed it.

What the Workers Tell You Can Help You Identify Psychosocial Hazards

Clues that psychosocial hazards existed are often revealed during interviews. An employee might say:

I wasn’t sure who was actually in charge.

We always do it this way when we get behind.

I’ve brought concerns about this before that were ignored.

These types of working conditions can’t be photographed or found in training records.

Good evidence collection helps investigators reconstruct more than a sequence of events. It helps them understand the environment in which people were making decisions. As you collect evidence, ask yourself:

What was this work asking of the people performing it?

That question may lead you to evidence you otherwise would have missed. And sometimes, that evidence changes the entire investigation.
