How mental health became HR’s strategic priority

For years, many businesses treated workplace mental health as a “nice to have”: something that sat in wellness programs, EAP brochures or posters on the wall. In 2025, that era is over.

Under Australian WHS law, psychological health now sits on equal footing with physical safety. That means HR leaders aren’t just encouraged to care about mental health, they’re legally required to treat workplace stress, burnout and psychological harm as seriously as any other safety hazard.

But this shift isn’t just about compliance, it’s also about performance. Every year, one in five Australians experiences poor mental health, costing the economy up to $22.5 billion annually. At the organisational level, every dollar spent on workplace wellbeing returns up to $2.30, according to Beyond Blue.

Whether you’re motivated by legal obligation or business opportunity, the message is the same: mental health has moved from the wellness corner to the boardroom. 

So if you’re looking to build a resilient, high-performing workforce that meets both legal requirements and business goals, here’s how to do it.

HR as the guardians of psychological safety

Workplace health and safety was once seen mainly through a physical lens with an emphasis on things like safe equipment, hazard controls and accident reporting. 

Now, under Australian WHS law, psychological health sits on equal footing with physical safety. That makes HR a frontline guardian of compliance as well as culture. 

In practice, HR professionals now wear two hats when it comes to wellbeing – that of cultural leader and compliance officer. But this isn’t just about law, it’s also about building a workforce that can perform sustainably under pressure. 

And it means HR needs to take the front foot on wellbeing in several ways. 

• Identifying psychosocial risks. HR leaders legally need to treat workload, job insecurity, bullying, harassment and lack of support as genuine safety hazards. Just as a loose wire might cause an injury, excessive hours or poor role clarity can cause burnout or psychological harm. Every risk assessment should explicitly include these factors.
• Embedding psychological safety into WHS systems. HR can ensure that risk registers, incident reporting processes and return-to-work procedures all reflect mental as well as physical health. For example, a “near miss” might not be just a physical fall, it could also be a case of someone raising a wellbeing issue that wasn’t addressed until it escalated.
• Setting clear accountabilities. Just as safety is “everyone’s responsibility”, psychological safety needs defined roles. HR can make sure that leaders, managers and staff all know their obligations, from early intervention to reporting obligations.
• Leveraging standards and frameworks: Global standards like ISO 45003 (psychological health and safety at work) provide a practical benchmark. Resources from Beyond Blue and Comcare can be integrated into HR systems to ensure practices meet both compliance and best-practice thresholds.
• Monitoring and reporting: Psychological safety isn’t a “set and forget.” HR can track indicators like absenteeism, turnover, EAP usage and pulse survey results to spot trends. Embedding wellbeing metrics into board reporting will make sure psychological risks get the same attention as other business risks. 

Done well, HR’s dual role doesn’t just prevent legal breaches, it will create a safer, more productive workplace where employees know their wellbeing is taken seriously. 

Building a ‘speak up’ culture 

The reality is that you can have all the best practices and policies in the world. But employees will usually only speak up about mental health when they trust their immediate manager will behave supportively. HR has a role to play in making sure this is the case. 

First, it can lead the company on talking openly about mental health, whether that’s by acknowledging stress in a busy period or through sharing personal experiences. It can also encourage leaders to do the same, by embedding mental health into leadership development, meetings and staff communications.

HR should also lead the drive to equip every manager with early intervention techniques, including recognising early warning signs such as changes in performance, disengagement or irritability. It should also make sure managers are trained in how to have supportive, non-judgemental conversations.

When employees feel they can raise concerns, admit mistakes or ask for help without fear of punishment, support becomes cultural. That means issues tend to get raised and addressed while they’re still manageable.  

Getting leadership commitment that sticks 

Beyond Blue calls out three non-negotiables for mentally healthy workplaces: leadership commitment, broad participation and ongoing communication. In practice, that means HR must do more than draft policies, it needs to coach leaders to live those values, make sure staff see and feel the commitment and ensure communication is consistent over time.

Here are some of the ways it can do just that.

• Flexible work and reasonable adjustments. Wellbeing shouldn’t live in a stand-alone document. It should cut across leave policies, flexible work arrangements, onboarding processes and return-to-work procedures. For example, flexible work requests should be seen as normal rather than as exceptions.

• Training managers to spot and respond to issues early. Most employees will raise mental health concerns first with their direct manager, not with HR. That makes line managers the front line. It’s critical that they’re trained in how to spot early signs of burnout, have difficult conversations and connect staff to professional support.

• Creating psychologically safe reporting channels. HR can build processes where employees feel safe to flag workload pressures, harassment or stress before these escalate. That might mean anonymous surveys, external hotlines or dotted-line reporting to independent committees.

• Holding leaders accountable. It’s not enough for leaders just to just sign off on wellbeing strategies, they also need to report on them. HR can help push for wellbeing metrics to be included into leadership’s KPIs, alongside financial and operational performance.

Building a resilient workforce 

Resilience in the workplace isn’t about telling people to “toughen up” or handing out mindfulness apps. It’s about creating the conditions where people can adapt, recover and keep performing without burning out. 

HR leaders can build resilience into the workplace systematically by focusing on both risk reduction and positive supports. 

For instance, Beyond Blue notes that role ambiguity is one of the biggest drivers of stress. Employees need to know what’s expected of them, how their role connects to the bigger picture and how they can achieve their workload. 

So HR can address this by auditing job design and using pulse surveys to identify teams where expectations are unclear or workloads are excessive.

HR can also try to model behaviours that prevent burnout by normalising practices like switching off after hours, enforcing minimum rest breaks and setting clear expectations around email and messaging. It should also monitor workload patterns (e.g. overtime, unused leave) and encourage regular check-ins for staff to raise pressures before they escalate. 

When these elements align, resilience stops being something you hope for and becomes something you can count on.

In short…

With Mental Health Week soon upon, the message for HR and business leaders is clear. Mental health isn’t a perk. It’s a strategic priority that drives performance, reduces risk and strengthens your workforce for the future.
