Building a psychologically healthy workplace isn’t just about avoiding burnout; it’s about creating an environment where people can thrive. While fruit bowls and yoga app subscriptions are well-intentioned, they don’t address the root causes of workplace stress, like a 10 PM email from a boss or the persistent unsaid ‘work all hour’s’ culture.
I like to support businesses utilising a variety of standards and legislative guidance. One of those standards is the ISO 45003, the first global standard providing practical guidance on manging psychological health, safety and well-being at work. It is a supporting guideline to the 45001 (occupational health and safety). I love using this standard as a guide, as it offers a practical roadmap for managing psychosocial risks. It’s a guide for protecting your team’s mental health as rigorously as you protect their physical safety.

What is ISO 45003?
ISO 45003 is an international guideline for managing psychological health and safety within an occupational health and safety (OH&S) management system. It is designed to be used alongside ISO 45001 to ensure mental wellbeing is integrated into a business’s DNA, rather than being an add-on.
The standard focuses on identifying psychosocial hazards—aspects of work design or management that can cause psychological harm. These hazards typically fall into three categories:
- Work Organisation: This includes ‘role ambiguity’ (not knowing what you’re supposed to do), ‘role conflict’ (conflicting demands), and unrealistic deadlines.
- Social Factors: These involve poor communication, interpersonal conflict, bullying, or a lack of support from managers.
Work Environment: Factors like inadequate equipment, poor lighting, excessive noise, or working in extreme conditions
Why Your Business Should Care?
Beyond the obvious moral and ethical implications, neglecting psychosocial risks has a measurable impact on your bottom line.
- Increased Costs: Higher rates of absence, turnover, and recruitment fees.
- Reduced Quality: More mistakes and lower overall productivity.
- Reputational Damage: Word travels fast when a workplace is a pressure cooker, making it harder to attract talent.
Conversely, effective management leads to improved worker engagement, enhanced productivity, and increased innovation.
A Guide to Achieving the Standard
You don’t need to be a therapist to implement these guidelines. Here is how to begin:
1. Secure Leadership Commitment
Psychological safety starts at the top. Management must demonstrate a genuine commitment by providing the necessary resources, time, budget, and people, to make mental health a priority.
2. Identify the Real Hazards (Ask Your People!)
You can’t fix what you don’t measure. Use a proactive approach to find out what is stressing your team:
- Surveys & Interviews: Use standardised questionnaires or group discussions.
- Data Review: Analyse incident reports, absenteeism data, and worker turnover.
- Workplace Observations: See firsthand how work is carried out and how teams interact.
3. Plan and Prioritise Actions
Once hazards are identified, prioritize them based on their potential for harm. Your action plan should focus on eliminating the hazard at the source—for example, by clarifying job descriptions or introducing flexible schedules to improve work/life balance.
4. Build Competence and Awareness
Ensure workers and managers are competent to recognise psychosocial hazards. This includes training managers on how to provide constructive feedback and spotting the early signs of burnout.
5. Build a Culture of Participation
Consultation with workers is essential at every stage. People are more motivated to contribute to a healthy workplace when they feel their voices are heard and they are involved in decision-making.
ISO 45003 isn’t about creating a workplace where everyone is happy 100% of the time, we know this is never going to happen! It’s about creating an environment where people aren’t being damaged by the way they are expected to work.
If you’re ready to move past wellness washing and build a truly resilient organisation, ISO 45003 can offer a really good starting point.
