Building Workplaces Where People Truly Thrive
Most of us are familiar with Maslow's Hierarchy of Needs, the idea that human beings must have their foundational needs met before they can pursue higher-order growth. We need food and shelter before we can think about belonging; belonging before we can build self-esteem; self-esteem before we can reach our full potential.
The same logic applies to psychological safety in the workplace. And yet, most organisations talk about psychological safety as though it's a single switch you can flip. Train the managers, run a workshop, hang a poster in the break room. Done.
But psychological safety isn't a destination. It's a layered architecture and if you skip the foundations, everything built above them becomes unstable.
This is where the Hierarchy of Psychosocial Safety offers a far more useful lens.
What Is Psychosocial Safety?
Before we explore the hierarchy, it's worth distinguishing between psychological safety and psychosocial safety, terms often used interchangeably but with an important difference.
Psychological safety, as defined by Harvard researcher Amy Edmondson, refers to a shared belief that the team is a safe space for interpersonal risk-taking, speaking up, asking questions, admitting mistakes, without fear of humiliation or punishment.
Psychosocial safety is broader. It refers to the protection of workers' psychological health and social wellbeing as a function of how work is designed, managed, and led. It is recognised in many jurisdictions around the world and in Australia as a legal and regulatory obligation under work health and safety law. It encompasses not just team dynamics but workload, job demands, role clarity, trauma exposure, fairness, and leadership behaviour.
In short: psychological safety is about the interpersonal climate. Psychosocial safety is about the whole system.
The importance of this distinction is constantly growing as boards, C-Suites, and executives are now responsible for implementation of these safety principles and must be aware of organisational risks to mitigate accordingly under Australian law.
The Hierarchy of Psychosocial Safety asks: what must be in place before people can genuinely thrive. Not just cope and comply, but bring their full capacity to their work and lives?
The Hierarchy: Layer by Layer
Layer 1 — Physical and Regulatory Safety (The Foundation)
At the base sits the most fundamental layer people must be safe from physical harm, and the organisation must meet its basic legal obligations. This includes adequate working conditions, protection from hazardous environments, and compliance with psychosocial hazard regulations.
In Australia, the model Work Health and Safety laws now explicitly require organisations to identify and manage psychosocial hazards. Things like high job demands, low job control, poor support, and exposure to traumatic content. This isn't optional. It is the base expectation.
Without this foundation, nothing else can function. An employee who is physically unsafe, or who works in a context of flagrant legal non-compliance, cannot access the higher rungs of the hierarchy. Survival precedes everything.
What this looks like in practice: Risk assessments that include psychosocial hazards. Clear policies. Incident reporting systems. Adequate staffing. Compliance with codes of practice.
Layer 2 — Freedom from Active Harm (Psychological Safety's Prerequisite)
The second layer is often where organisations fail before they even begin to discuss "psychological safety." Freedom from active harm means employees are not experiencing bullying, harassment, discrimination, chronic humiliation, or leaders who use fear as a management tool.
This tier does not mandate comfort. Work involves challenge, difficult feedback, and stretching beyond what feels easy. But there is a categorical difference between a challenging environment and a harmful one.
When people are subjected to repeated mistreatment, whether overt or covert, their nervous systems respond accordingly. They enter threat states that compromise cognition, creativity, and collaboration. They begin investing energy in self-protection rather than performance. Trust erodes. People disengage or leave.
No amount of team-building, values workshops or one-off training can compensate for active harm operating within the system.
What this looks like in practice: Zero tolerance for bullying and harassment that is genuinely enforced, not just stated. Leaders who model respectful behaviour. Mechanisms for people to report concerns without fear of retaliation that include qualitative and quantitative feedback. Managers who are held accountable for how they lead, not just what they deliver, is imperative.
Layer 3 — Fairness, Voice, and Inclusion
Once active harm is addressed, the next layer concerns whether people experience the organisation as fundamentally fair, and whether they feel they have a voice in matters that affect them.
Organisational justice research consistently shows that perceived fairness in how decisions are made, how people are treated, and how outcomes are distributed is one of the strongest predictors of trust, engagement, and wellbeing. When people feel the system is rigged, or that their perspective doesn't matter, disengagement follows even in otherwise functional environments. This is where psychosocial and psychological harm deeply impacts organisations and individuals. A leader's capacity to put down their ego to hear what they are missing is essential and requires extremely high emotional intelligence.
Inclusion sits within this layer too. Belonging is not simply about diversity in representation; it's about whether people feel they can show up as themselves, that their contributions are valued, and that they are not required to mask or minimise their identity to be accepted.
What this looks like in practice: Transparent decision-making. Genuine consultation, not performative engagement. Leaders who actively seek out dissenting views and sit with the discomfort these responses often bring without reacting but remaining curious. Equity in how opportunities, recognition, and accountability are distributed. Cultures where difference is genuinely welcomed.
Layer 4 — Psychological Safety (Interpersonal Risk-Taking)
Only now, once the lower layers are reasonably stable can we meaningfully pursue psychological safety. Under Edmondson's definition: the conditions under which people feel safe to speak up, challenge assumptions, raise concerns, and take interpersonal risks without fear of punishment.
Psychological safety is often measured at the team level, and rightly so. A person might feel psychologically safe in one team and not another, even within the same organisation. Leadership behaviour is the single biggest driver. Leaders who model vulnerability, respond non-defensively to challenge, and reward candour over conformity create the conditions for it to emerge. This is where self-regulation becomes a superpower of exceptional leaders.
Psychological safety is not about eliminating accountability. The highest-performing teams hold each other to high standards and feel safe enough to be honest. These are not in tension, they are complementary.
What this looks like in practice: Leaders who say "I don't know" and "I was wrong." Retrospectives that examine failure without blame. Meetings where the quietest voices are actively sought. Feedback cultures built on curiosity, not evaluation, blame or dismissal of an individual or idea.
Layer 5 — Growth, Meaning, and Flourishing
At the apex of the hierarchy sits the conditions under which people don't just avoid harm but genuinely flourish and where work becomes a source of meaning, mastery, and contribution.
This includes having work that is appropriately challenging, aligned with personal values, and connected to a sense of purpose. It includes opportunities for learning and development, recognition that is specific and sincere, and the autonomy to shape how work gets done.
Flourishing is not a luxury. Research in positive psychology and occupational health consistently shows that people who experience meaning and growth at work are more creative, more resilient, more collaborative, and more productive. When this layer is satisfied, the benefits to an organisation are undeniable and exponential.
What this looks like in practice: Meaningful work design. Clear paths for development. Leaders who know what matters to each person on their team and can read where both individuals and the team as a collective are at. Cultures of recognition that are not tokenistic or insincere. Autonomy within clear, evolving expectations visible within the individual, team, organisational culture, and overall success of the business.
Why the Hierarchy Matters
The Hierarchy of Psychosocial Safety reframes the conversation in a critical way, it tells us that where we intervene matters as much as how.
Investing heavily in wellbeing programs and psychological safety workshops while ignoring bullying, inequitable processes, or leaders who rule by intimidation is not just ineffective, it can actually deepen disengagement by signalling that the organisation is more interested in appearance than substance.
Build from the bottom up. Address active harm before promoting flourishing. Establish fairness before asking for vulnerability. Comply before you aspire.
The hierarchy isn't about lowering ambition. It's about building something that will actually withstand the complexity of humanity.
