The connection between inclusion and mental health

Google will tell you in seconds that workplace inclusion and mental health are deeply interconnected. And it’s right. But knowing something and really acting on it are two very different things – and when it comes to inclusion, most workplaces haven’t made the leap.

When most leaders talk about workplace mental health, they reach for the obvious levers – workload, job security, management quality, burnout. And they’re right to. These things matter enormously. But there’s a dimension that keeps getting underweighted, quietly shaping how people experience every single workday: whether they feel like they genuinely belong.

This isn’t about making work feel like a group hug. It’s about something more fundamental – the human need to feel seen, valued, and safe enough to show up as yourself. And when that need goes unmet at work, the consequences show up in the data in ways that are hard to ignore.

The numbers tell a human story

Research from the Diversity Council Australia puts a striking number on what many of us sense intuitively. Workers in inclusive teams were six times more likely to report that work had a positive impact on their mental health over the past year – 57% versus just 9% in non-inclusive teams.

Think about that gap for a moment. Same economy. Same labor market. Very different human experiences – determined largely by whether the team around you makes you feel included or not.

The leadership dimension is just as significant:

  • Workers with inclusive managers were nearly four times more likely to report positive mental health outcomes (53% vs. 14%)
  • Workers in inclusive organizational cultures saw a similar four-times lift (50% vs. 13%)

The TELUS Mental Health Index adds another layer: more than one in three workers across Europe currently carry high mental health risk. And nearly half lack trusted workplace relationships – making them three times more likely to feel isolated at work.

These aren’t abstractions. They’re real people spending real hours of their lives feeling like they don’t quite fit, can’t quite trust, or don’t quite matter. And a BCG survey found that employees who feel free to be themselves at work are 2.4 times less likely to quit – yet most organizations still don’t treat belonging as a strategic priority, because it feels too intangible to act on.

What “feeling included” actually looks like

Inclusion isn’t built in all-hands meetings or diversity statements. It’s built in the small moments that accumulate across a working week – being genuinely listened to in a meeting, being considered for a stretch opportunity, having a manager who notices when something’s off and creates room to talk about it.

It’s also deeply personal. People’s experiences of inclusion – and exclusion – are shaped by their backgrounds, identities, and histories in ways that aren’t always visible to those around them. What feels welcoming to one person can feel alienating to another. That’s not a problem to solve with a single policy. It’s a reality to design around, thoughtfully and continuously.

Diversity brings different people into the room. Inclusion is what makes the room actually work for all of them.

How to actually build it: The CLEAR framework

Most inclusion efforts struggle not because people don’t care, but because they start in the middle – a training here, a policy update there, a well-intentioned initiative that doesn’t connect to anything systemic. What actually moves the needle is building inclusion as a coherent practice, from the conditions that make it possible to the culture that makes it last.

Here’s a framework we’ve found useful:

C – Culture from the top. Inclusion has to be modeled by leadership before it can be expected anywhere else. This isn’t about sending the right email or showing up at the right event. It’s about how leaders run meetings, who they sponsor, how they respond when someone pushes back, and whether they genuinely make space for people who think differently. People watch leaders closely. What they see shapes what feels safe – or not.

L – Listen before you act. It’s tempting to skip straight to solutions. But the most effective inclusion efforts start with listening – understanding where people actually feel excluded, where trust breaks down, and which groups are having experiences that leadership might not be aware of. A proper inclusion diagnostic, done well, often surfaces things that surprise even well-meaning organizations. That surprise is valuable.

E – Everyday moments, not big gestures. The texture of belonging is built in daily work – who gets credit in a meeting, whose ideas get picked up and run with, who gets asked for input before a decision is made. These micro-experiences accumulate into how someone feels about their place in a team. Training people to notice and shift these moments is where real culture change happens – quietly, consistently, over time.

A – Activate your managers. No single factor shapes an employee’s sense of inclusion more than their direct manager. More than organizational culture, more than company values, more than any program HR runs. Managers who know how to create psychological safety, give feedback equitably, and genuinely advocate for their people can transform the day-to-day experience of belonging. Inclusive management is a skill – and like any skill, it can be taught.

R – Reinforce and revisit. Inclusion isn’t a destination. The organizations that sustain it treat it as an ongoing practice – with regular pulse checks, open feedback channels, mentorship structures, and a genuine commitment to acting on what they hear. The goal isn’t the absence of problems. It’s creating an environment where people believe that raising a concern will lead somewhere.

This is worth getting right

Mental health at work is a performance issue, a retention issue, and – most importantly – a human issue. And inclusion is one of the most powerful levers we have for supporting it. Not through grand gestures, but through the steady, intentional work of making people feel like they belong.

The organizations that get this right won’t just have better wellbeing scores. They’ll have more engaged teams, better retention, and cultures where people actually want to show up and do their best work.
