Psychological resilience, not technical skill, will define leadership success in the AI era, according to psychologist and executive coach Dr Marie-Hélène Pelletier. As organisations accelerate AI adoption, the strain on leaders' judgement and their teams' sense of identity is becoming a central risk that most HR frameworks aren't yet equipped to absorb.
Pelletier, whose TEDx talk "Crossing the River: Resilience in the Age of AI" established her as a leading voice on workplace resilience, said the pressure to adapt "faster" challenges decision-making in ways few organisations have prepared for. "We still have to, as leaders and as HR leaders as well, continue to make good decisions, responsible decisions, but at the same time, with everything happening so fast, it just becomes harder to maintain good judgement - we're seeing some ethical drift," she said, describing professionals who unknowingly lean more on technology than they realise.
The end of knowing everything
Senior leaders, she said, were often promoted in a more predictable era where it was possible to "know everything about everything." That certainty has disappeared. Without it, leaders risk drifting from their own ethical standards without noticing - a subtle but costly shift. "We're seeing some ethical drift," Pelletier said. "People see themselves as ethical but are, without realising it, relying a bit more than we think on technology."
Resilience as leadership infrastructure
For Pelletier, the response isn't another wellness programme. "Resilience has moved up from being a nice wellness concept over on the side to being very central - to being actually leadership infrastructure," she said. This reframing means resilience is now a strategic concern, central to AI for Executives & Strategy. The shift matters because HR data already shows a decline in employee confidence that leaders genuinely prioritise wellbeing - even as organisations expand wellness budgets. Recent workplace research on overload and organisational design found that trust in leadership's commitment to wellbeing has fallen steadily over five years.
Identity disruption and the isolation risk
AI doesn't just change tasks; it quietly reshapes professional identity. "What we do in our work is in part defining our identity," Pelletier said. "AI coming in and modifying what we can do is impacting our identity, which means it might bring us closer to what we could call our ideal work self - or it could be moving us away from it." Her advice to leaders is to go beyond generic check-ins and ask specifically how AI is affecting a person's sense of meaning and satisfaction at work. Naming that shift, she added, is protective: "One of the things we know about humans is when we can name things, it helps us process them, make sense of them."
That risk of quiet disconnection shows up in a global report on AI's effect on workplace communication, which found a meaningful share of employees now speak less to colleagues since adopting generative AI tools. Meanwhile, research by Boston Consulting Group identified a pattern researchers call "AI brain fry" - mental fatigue linked to heavy oversight of multiple AI tools, marked by mental fog, slower decision-making and headaches. The study found that intensive AI oversight was associated with roughly 12% greater mental fatigue and 19% greater information overload among surveyed employees. ManpowerGroup's 2026 Global Talent Barometer of nearly 14,000 workers across 19 countries revealed that while regular AI use rose sharply in 2025, workers' confidence in the technology fell by around 18% - a gap attributed largely to tools being rolled out without adequate training or context.
What effective leaders do differently
The strongest leaders Pelletier works with share two habits. First, they invest in consistent AI training - structured, ongoing learning that gives people a sense of agency. "In the absence of training or information, we will make assumptions - and assumptions can be dangerous, can be not helpful," she said. Second, they deliberately build their own resilience through exercise, sleep, nutrition, relationships and boundaries, rather than waiting until they're depleted. "Now is better than any time after now," she said.
To counter the isolation risk, Pelletier recommends creating standing cross-functional groups where people can discuss how AI integration is going from a human perspective. For leaders who worry they've missed the window: "If someone's thinking, well, we're too early for this - no, you're not. Do it now. If you're thinking it's too late, we're already too far - no, no, it's not. Do it now."
Why this matters for HR leaders
HR teams cannot treat resilience as a side programme. The data shows that expanding wellness offerings without addressing the psychological toll of AI oversight leaves a disconnect. Prioritising consistent training and structured identity conversations is at the heart of AI for Human Resources. Practical steps include funding ongoing AI literacy, embedding questions about work identity into regular check-ins, and creating facilitated forums where employees can voice how AI is changing their relationships and sense of purpose. The window to act is now - not when burnout and detachment become visible in exit interviews.
