Psychosocial hazards - what are my obligations?

Australia’s Psychological Health and Safety Regulations

Under the Work Health and Safety Act 2011, a person conducting a business or undertaking (PCBU) has a primary duty to ensure, so far as reasonably practicable, both the physical and psychological health and safety of their workers.

Previously, the management of psychosocial risks has been unregulated Australian workplaces. However, with the rising frequency and costs of psychological injuries, and after multiple WHS legislation reviews, State and Territory Ministers have committed to introducing regulations across Australia to elevate psychological health and safety to the same level as physical health and safety.

These new regulations recognise that hazards that pose a risk to psychological health and safety (psychosocial hazards) are just as harmful to workers as physical hazards are. They will also provide clearer guidance to employers on their obligations to better protect workers from mental illness and injury.

In June 2022, SafeWork Australia amended the Model Work Health and Safety Regulations to include the management of psychosocial risks. Later in July, they released a Code of Practice on managing psychosocial hazards at work, which provides practical guidance on how to identify and manage psychosocial risks and achieve the standards required under the regulations. It is now up to the individual states and territories to adopt these changes into their WHS legislation.

On October 1, 2022, NSW became the first state to adopt new WHS regulations, which require businesses to implement control measures to manage psychosocial risks. Queensland have also announced their commitment to adopt the same regulations on 1 April 2023.

Background to the new work health and safety regulations

  • SafeWork Australia commissioned an independent review of the model WHS laws (the Boland Review). The review noted that there was a consistent view that psychological health is neglected in the laws. The final report contained 34 recommendations including to “Amend the model WHS Regulations to deal with how to identify the psychosocial risks associated with psychological injury and the appropriate control measures to manage those risks” (Boland 2018). [1]

  • SafeWork NSW became the first state to introduce an industry-wide Code of Practice on Managing Psychosocial Hazards at Work. The code sets out what businesses should do, in line with their legal responsibilities, to address hazards in the workplace that have the potential to cause psychological or physical harm. [4]

What will the new regulations mean for you?

As an employer you will be required to manage psychosocial hazards in your workplace, the same as you currently must do for physical hazards.

To do this you will need to follow a systematic approach, in consultation with staff, to identify psychosocial hazards, assess and prioritise the risks, develop and implements control measures and regularly review the effectiveness of these controls.

At Healthy Business, we understand that the proposed changes and the associated costs may be a challenge for businesses. However, it is important to note that the potential benefits of establishing a mentally healthy workplace are substantial, for both your people and your business.

In comparison to other injuries, psychological injuries can be some of the costliest. According to SafeWork Australia statistics, the average cost of a mental injury claim has risen 22% in the last decade, reaching $46,400 in 2018-19. This was more than three times the average amount for all other serious claims ($14,500). This is largely due to the fact that the time of recovery is much longer, with claims of a psychological nature having an average duration of 26.6 weeks in 2018-19, compared to 7.3 for all other claims. [6]

Additionally, poor mental health can negatively impact on a person’s performance, productivity and attendance at work. The Productivity Commission estimated that absenteeism and presenteeism from mentally ill-health are costing Australian workplaces approximately $17 billion each year. [7]

On a positive note, a Regulatory Impact Statement prepared by Deloitte found that the effective management of psychosocial hazards could exceed the costs for Australian workplaces at a ratio of 1:1.06. This is due to the benefits from improved productivity from lower absenteeism and presenteeism, and reduced compensation claims and occurrence of employee mental illness and injury. [8]
