As at 2021, 18.8 percent of Victorians were casual workers. This number is likely an underestimate however, as the data was collected during the COVID-19 lockdowns which resulted in job losses for many casual workers - a case in point as to the risks associated with insecure work!
Insecure work, while not yet recognised by WorkSafe as a psychosocial hazard, is recognised as a risk factor under other jurisdictions such as Western Australia. The union movement and HSRs know that insecure work, which includes casual work, insecure contracting, gig economy work, fixed term contracts and labour hire work, can have detrimental impacts on workers mental health.
When workers have little or no access to paid leave or entitlements and are not sure if they are going to have a job the next day, their mental health suffers. Physical or psychological illness that might affect performance or the ability to come to work are often ignored and workers push through knowing that if they don't come to work, they won't get paid. This need to choose between paying the rent and looking after yourself has serious impacts on mental wellbeing, often exacerbating mental illness. Additionally, an inability to plan for the future, take time off and a feeling that one is dispensable, all cause psychological harm.
All of this has been confirmed by research from organisations such as the International Labour Organization, Edith Cowan University and many others.
