When I was working as a paramedic, there was no such thing as a quiet shift. You might have a lull between calls, but there was no genuine downtime. You were either responding, restocking, completing clinical notes, or waiting for the next job knowing it could be anything from a low-acuity transport to a cardiac arrest.
That kind of sustained demand, with no real ability to control your workload or predict what's coming, is a textbook psychosocial hazard. High job demands combined with low job control. It's one of the most well-established risk factors for psychological injury in occupational health research, and it's one of the 18 psychosocial hazard categories under Australian WHS frameworks.
I didn't need the research to tell me this. I lived it. And when I became an OHS inspector at WorkSafe Victoria, I saw the same pattern playing out in workplaces that looked nothing like an ambulance.
What high job demands means
High job demands isn't just 'being busy.' Under the Code of Practice for managing psychosocial hazards, it refers to work that is physically, mentally, or emotionally demanding to a degree that creates a risk to health.
This includes:
• Sustained high workloads with insufficient time to complete tasks to a reasonable standard
• Emotional demands — being required to manage the distress, aggression, or suffering of others
• Cognitive demands — complex decision-making under pressure with limited margin for error
• Time pressure — tight deadlines with consequences for missing them
• Competing demands — multiple tasks or roles with no clear priority or allocation
In paramedicine, all five of these were present simultaneously, most shifts. But the same combination exists in healthcare, education, social services, aged care, hospitality, and any work where people are expected to do more with less.
Why employers keep getting this wrong
The most common mistake I see is employers treating high workload as a temporary problem rather than a structural one. 'We're in a busy period.' 'We'll get more staff next quarter.' 'Just push through until the project lands.'
In paramedicine, the busy period was every period. Demand never dropped to a level where the workload felt manageable. And the systemic response was to add more calls to the same crews rather than redesign how work was allocated.
I see the same dynamic in the workplaces I assess now. A team of five is doing the work of eight. One person leaves, and the remaining four absorb the load. Nobody adjusts deadlines, reduces scope, or redistributes tasks. The expectation is that the people still there will simply work harder, faster, or longer. And when they burn out, the response is to replace them rather than fix the workload.
This is not a staffing problem. It's a hazard management failure. And under OHS legislation, it's the employer's responsibility to control it.
The link between demands and burnout
Burnout is not a clinical diagnosis. It's a state of chronic workplace stress that has not been successfully managed. The World Health Organization defines it by three characteristics: exhaustion, mental distance from one's job, and reduced professional effectiveness.
What makes burnout a psychosocial risk issue, rather than just an HR concern, is that it's caused by work conditions, not personal weakness. A paramedic who burns out after years of sustained high demand isn't failing to cope. They are responding normally to abnormal conditions. The same applies to the teacher managing 30 students with no aide, the aged care worker with a 12-resident load, and the project manager running three projects with no additional resourcing.
Burnout is the outcome. The hazard is the work design that makes it inevitable.
What employers should be doing
Managing high job demands starts with treating workload as a psychosocial hazard, not a performance metric. Here's what that looks like in practice:
• Assess whether workloads are realistic and sustainable. Ask workers, not just managers, whether the current demands can be met within ordinary working hours, to a reasonable standard, without sustained overtime.
• Build recovery into work design. In paramedicine, the absence of recovery between calls was a known problem. Most workplaces can do better by having scheduled breaks, task rotation, protected time between high-demand periods.
• Match demands to resources. If the workload has increased but staffing hasn't, that's a hazard. If a role requires skills the worker doesn't have and hasn't been trained in, that's a hazard. If someone is doing two jobs because a position hasn't been filled, that's a hazard.
• Monitor leading indicators. Absenteeism, presenteeism, overtime hours, turnover in specific teams, these are signals of unmanaged demand, not just operational data.
• Don't rely on individual solutions for systemic problems. An EAP referral is not a control for excessive workload. Yoga classes and resilience training are not substitutes for appropriate staffing.
The bottom line
I left paramedicine because a back injury forced me to. But the physical injury wasn't the whole story. Years of sustained high demand, the emotional weight, the broken sleep patterns, the inability to ever fully switch off, had taken a toll that was harder to measure but just as real.
I went on to spend over a decade at WorkSafe investigating exactly these kinds of hazards in other people's workplaces. What I saw confirmed what I already knew: burnout is predictable, and it's preventable, if the employer treats it as a work design problem rather than a worker problem.
If your workers are consistently overloaded, consistently stressed, and consistently telling you they can't keep up it's a psychosocial hazard, and it needs to be managed as one.
