Aoife O’Brien on why people leave, and what good leaders do differently

Aoife O’Brien came to her subject the hard way. Before the podcast, before the consultancy, and before her debut book, there were two bruising corporate experiences that forced her to examine what work actually asks of people and what organisations too often fail to provide. O’Brien had spent 20 years in market research, advising large global brands and working in a field that suited both her skills and temperament. Then came the setbacks that changed direction. In one role, after being repeatedly told she would be promoted, she found that a male colleague had instead been made her manager without any proper conversation. In another, she found herself in a culture that shifted from energising to corrosive.

What good leaders do differently

What matters in O’Brien’s account is not grievance but analysis. She does not present herself as a victim of bad luck. She presents herself as someone who began asking better questions. “What could I have done differently to choose something better for myself?” she said.

Then came the organisational question. “How can we create these environments where people actually want to stay and they want to do their best work?”

That line of thinking took her back to study. O’Brien completed a master’s in organisational behaviour and turned the work into two connected platforms: the Happier at Work podcast and her debut book, Thriving Talent: How Great Leaders Drive Performance, Engagement and Retention, due for publication on 30 March 2026. The podcast, she said, began because the research she was reading was too important to remain locked inside academic language. “They’re very academic. They’re very heavy, they’re very deep,” she said of the journal articles. More importantly, “they’re not getting into the hands of the people who really need them.”

O’Brien’s central argument is a practical one. Better workplaces are not built by slogans, perks or polished values statements. They are built by leaders who understand what people need in order to perform well and remain engaged. She is also clear that this is not solely an HR issue. “I now realise that that’s not necessarily HR’s job. Actually, leaders can take responsibility in these situations as well.”

At the centre of her framework is psychological safety. O’Brien describes it as the foundation rather than an optional extra. In her words, it is about “feeling safe to speak up what’s on your mind”, whether that means pushing back on workload, offering a different view, or raising a new idea. She makes an important distinction here.

“Safety is different from comfort.”

That is the point. A healthy workplace is not one where difficult conversations disappear. It is one where those conversations can happen without retaliation. O’Brien’s view is that most organisations do not begin there. “The default tends to be psychologically unsafe,” she said.

O’Brien is at her most effective when she translates theory into management practice. Asked how leaders create psychological safety, her answer is practical and disciplined: they follow through on commitments, approach problems with curiosity rather than blame, show consideration for their teams, and act with consistency. They must also be willing to acknowledge when they do not have the answer. As she put it, “I think sometimes, as leaders, we feel like we’re expected to know absolutely everything,” but a simple admission such as “I don’t have the answer, but I can find out” can materially improve the tone and trust within a team.

There is nothing fashionable or vague in this. O’Brien is talking about managerial discipline. The same is true of her view of culture. She has little patience for the inflated language that often surrounds it. Culture, in her account, is not what a company says about itself. It is what people experience. “The leaders create the culture that we live in,” she said. Values matter only if behaviour follows. She offered a telling example from one former employer whose stated value was simplicity while its day to day procedures were highly bureaucratic. The inconsistency mattered because employees notice it immediately.

O’Brien is equally direct on what happens when poor behaviour is tolerated in the name of results. If a leader brings in sales but behaves as a bully, staff draw their own conclusions. “That’s what essentially becomes your culture,” she said. It is a useful corrective to the common corporate habit of treating bad behaviour as a personality issue rather than a leadership failure.

For O’Brien, culture is defined by what gets tolerated and by what people are held accountable for.

She is not naïve about how hard that can be. In competitive organisations, some leaders have been rewarded for years for behaviours that diminish everyone around them. Changing that requires more than aspiration. It requires decisions. “It’s not just about what you achieve, it’s about how you achieve it as well,” she said. Again, the point is managerial rather than moral. Toxic behaviour costs money, erodes trust and drives people out of the business.

O’Brien’s podcast has become an extension of this work. What began as an interview format has widened to include solo episodes and listener questions. She speaks with authors, psychologists and leaders, then distils the lessons for an audience trying to make sense of work as it is actually lived. One recent listener question, she said, came from someone who felt busy all the time but had nothing to show for it. That, too, is part of her territory: performance, focus and the gap between effort and impact.

She also spends time on imposter syndrome, a subject often framed too narrowly. O’Brien pushes back against the assumption that it is chiefly a female problem. “I think that’s an urban myth,” she said. Her own research suggests that men and women experience it to the same degree, even if they express it differently. What struck her most when she first began speaking publicly about it was how many men replied privately to say they had never known it had a name.

Imposter syndrome: “I thought it was just me,” they told her. It is a small but useful reminder that workplace confidence is often more fragile, and more widely distributed, than appearances suggest.

The through line in O’Brien’s work is clarity. She is not trying to make work softer. She is trying to make it more honest and better led. Her case is that organisations perform better when people can speak plainly, when culture matches intent, and when leaders understand that retention is rarely about loyalty in the abstract. People stay where they are trusted, heard and managed properly. That is the premise of Happier at Work. It is also the argument of her first book.
