Quick answer: Mail Sorters are notably more stress-exposed than most Australian occupations — ranked #81 of 317 by workplace mental health hazard exposure, with a composite stress score of 51.5/100 against a national average of 47.4. The biggest drivers are lack of control and pace and demands.
Mail Sorters stress profile vs the national average
Each occupation is scored across six categories of workplace mental health hazard, built from 22 stress factors identified in SafeWork Australia's occupational hazards data. Higher scores mean greater exposure.
- Emotional demands40.4 vs 37.9 avg
- Responsibility burden45.5 vs 60 avg
- Pace and demands66 vs 56 avg
- Lack of control45.8 vs 24.5 avg
- Precision and monotony71.2 vs 67.7 avg
- Physical environment40.1 vs 38.2 avg
Scores range 0–100; higher = more stress-inducing. Source: SafeWork Australia Beta Occupational Hazards Dataset.
What drives the score for mail sorters
Compared with the average Australian occupation, mail sorters score furthest above the norm on lack of control (45.8 vs 24.5 average), pace and demands (66 vs 56 average) and precision and monotony (71.2 vs 67.7 average). The single biggest individual stress factor is time pressure at 92.2/100 — against an all-occupation average of 71.6.
The occupation scores below the national average for responsibility burden (45.5 vs 60), which moderates the overall ranking.

Understand these hazards
The elevated stress categories for mail sorters map to recognised psychosocial work factors under ISO 45003 and Australian WHS legislation. Learn what each one is and how it can be controlled:
- Exposure to Violence →Whether workers face the risk of physical or verbal aggression at work.
- Exposure to Trauma →Whether workers encounter traumatic events or material as part of their role.
- Work Interaction →The quality of relationships and interactions within the team and organisation.
- Work Demands →The volume, pace, and complexity of what is asked of workers.
- Schedule and Hours →The arrangement of working time and its effect on health and recovery.
- Autonomy →The degree of control workers have over how they do their work.
Methodology
Clearhead scored 317 occupations in the Australian and New Zealand Standard Classification of Occupations (ANZSCO) using SafeWork Australia's Beta Occupational Hazards Dataset. We kept only the 22 hazard variables relating to mental health — such as conflict exposure, decision-making pressure, and time pressure — and deliberately excluded physical safety risks like working at height.
The 22 variables are grouped into six categories: emotional demands, responsibility burden, pace and demands, lack of control, precision and monotony, and physical environment. An occupation's composite score is the equally weighted average of its six category scores. All scores run 0–100, where higher means more stress-inducing.
Two control-related variables are reported by SafeWork with inverted polarity (“freedom to make decisions” and “structured versus unstructured work”). We reverse these and present them as lack of autonomy to make decisions and amount of highly structured work, so that a higher score consistently indicates greater stress exposure.
Hazard exposure describes the average conditions of an occupation, not any individual's experience — everyone has a different tolerance for these challenges, and conditions vary between workplaces.
Frequently asked questions
Mail Sorters: how stressful is the job?
Mail Sorters rank #81 out of 317 Australian occupations for workplace mental health hazards, with a composite stress score of 51.5/100 against a national average of 47.4. That makes the occupation more stress-exposed than 74.4% of Australian jobs.
What are the biggest mental health stress factors for mail sorters?
The highest-scoring hazards are time pressure (92.2/100), sounds and noise levels are distracting or uncomfortable (85/100) and importance of being exact or accurate (76/100). Overall, the occupation scores above the national average in emotional demands, pace and demands, lack of control, precision and monotony and physical environment.
Which stress factors are lower for mail sorters?
Mail Sorters score below the national average for responsibility burden (45.5 vs 60 average), which partially offsets the higher-scoring hazards.
Where does this data come from?
Scores are derived from SafeWork Australia's Beta Occupational Hazards Dataset. Clearhead filtered the dataset to the 22 mental-health-related hazard variables — excluding physical safety risks — and scored 317 ANZSCO occupations across six categories: emotional demands, responsibility burden, pace and demands, lack of control, precision and monotony, and physical environment.
