Delphine Tordjman is a multi-published author, executive coach for the likes of the Paris Olympics to Balenciaga, and leadership expert specializing in engagement and mental health at work. Author of Réussir sa carrière sans rater sa vie (Géreso, 2025), she helps leaders build sustainable performance aligned with meaning.
Her approach integrates organizational psychology, somatic awareness, and cultural transformation.
The modern workplace is defined by a relentless pursuit of results. But when the pressure to perform outpaces our capacity to recharge, the inevitable cost is burnout. How can we redesign our approach to work so that high performance becomes an enduring, healthy practice rather than a sprint? In this conversation, Culture Vitale unpacks the foundations of sustainable performance with somatic intelligence expert, Delphine Tordjman.
PERFORMANCE VS. SUSTAINABLE PERFORMANCE
Sustainability and performance are not usually words that go hand-in-hand. Yet, being able to sustain performance is crucial today in our ever-evolving world. What is the fundamental strategic difference for a leader or organization that focuses on sustainable performance rather than classical performance?
Sustainable performance and classical performance differ not by intensity, but by their relationship to time, energy, and human durability. For decades, organizations rewarded acceleration, optimization, and short-term measurable output. Yet contemporary occupational psychology demonstrates that chronic overload combined with insufficient recovery is one of the strongest predictors of burnout and disengagement¹.
Conversely, autonomy, intrinsic motivation, and psychological safety are consistently associated with long-term engagement, learning capacity, and collective performance². Sustainable performance can therefore be defined as the capacity of a leader, professional, or organization to remain effective over time without degrading human energy, mental health, or meaning.
Biologist Olivier Hamant introduces the concept of robustness in living systems: systems optimized only for efficiency become fragile, whereas robust systems preserve margins, diversity, and adaptability. Applied to organizations, robustness means prioritizing cooperation, recovery, and resilience over pure optimization.
Research from La Fabrique Spinoza confirms this shift: meaning at work, quality of relationships, and emotional climate are decisive drivers of engagement and health. When meaning declines, absenteeism rises, while positive emotional climates strongly correlate with performance³. True success is therefore not about going faster, but about lasting longer without losing oneself — a central idea developed in my latest book “Réussir sa carrière sans rater sa vie” (Géreso, 2025).
MORE EFFECTIVE MEASUREMENTS AND STANDARDS
On a personal level, a common complaint is the classic ‘I don’t have time to slow down.’ You argue that the solution isn’t better time management, but better ‘boundary management.’ What is the practical difference between the two for someone with a packed calendar?
Time management organizes the schedule. Boundary management protects energy. Many executives believe they lack time, while in reality they lack clear internal consent and embodied limits. Consent is widely discussed in society regarding physical integrity, but consent is a far broader psychological and leadership question:
• Do I truly consent to answering emails late at night?
• Do I consent to unrealistic deadlines that repeatedly eliminate recovery time?
• Do I consent to rhythms that disconnect me from bodily signals?
Elite athletes embody sustainable performance: their excellence lies not only in pushing limits, but in sensing precisely when the body would break if pushed further. High-level leadership requires this same somatic intelligence.
On an organizational level, we are used to measuring performance by quarterly output. With a proposed shift to ‘sustainable performance’ — if we were pitching this to a skeptical CFO or CEO, how would you define the ROI of this shift?
The ROI of sustainable performance is visible in three strategic indicators: reduction in absenteeism and turnover, increased innovation and adaptive capacity, and improved employer brand and talent attraction. Organizations that invest in mental health and recovery see measurable returns: fewer hidden costs linked to disengagement, more creative and resilient teams, and enhanced ability to attract and retain top talent in an increasingly competitive market.
Many organizations and professionals also believe that pressure and intensity are a necessary evil for results. How can high performance be made compatible with well-being, and are there any tradeoffs?
High performance and well-being are not opposing forces when organizations shift from extraction-based to regeneration-based models. The tradeoff is not between performance and health, but between short-term intensity and long-term effectiveness. Sustainable performance requires accepting that recovery time is productive time, that psychological safety enhances rather than threatens accountability, and that human limits are not obstacles to overcome but vital information to integrate.
THE ECOSYSTEM OF ADDICTION
Work addiction, as you’ve pointed out, can be a socially valued addiction. What are the early warning signs that someone is crossing the line from engagement into dependency, and to an unhealthy level?
Work addiction is one of the most paradoxical addictions of our time, because it is often socially rewarded rather than questioned. In many organizations, exhaustion is still confused with commitment, and hyper-availability with leadership potential.
The shift from healthy engagement to unhealthy dependency is rarely sudden. It appears through progressive micro-signals:
• the inability to disconnect without guilt
• the disappearance of recovery time (evenings, weekends, vacations)
• a growing emotional emptiness when not working
• chronic fatigue, sleep disruption, irritability, or somatic pain
Research in occupational health shows that overinvestment combined with lack of recovery is a major pathway toward burnout (Maslach & Leiter)¹. At this stage, work no longer nourishes identity it replaces it.
Then there is the phenomenon of ‘blurring’ — the erasure of boundaries by digital tools, exacerbating the addiction. Is work addiction today a result of individual psychology, the digital impact on individuals, or organizational systems that enable this? And how do we alleviate this?
Work addiction cannot be reduced to individual psychology alone. It emerges from an ecosystem composed of three interacting layers:
1. Individual dimension: Perfectionism, need for recognition, or fear of failure increase vulnerability.
2. Digital acceleration: Permanent connectivity removes natural recovery boundaries and creates a culture of continuous urgency.
3. Organizational systems: When performance metrics reward availability, speed, and overload, addiction becomes structurally reinforced.
As the British economist Charles Goodhart famously noted in the 1970s, “when a measure becomes a target, it ceases to be a good measure.”
In practice, this means that people tend to focus on hitting the numerical target in order to prove performance, even if the original meaning of the objective is lost. For example, if the goal is to make ten client calls per day, employees may call anyone simply to reach the number, rather than to create real value or meaningful relationships.
Applied to work addiction, this dynamic is crucial: when organizations reward intensity, speed, and constant activity through measurable indicators, individuals learn to equate overwork with success. What looks like personal addiction is often a systemic response to measurement systems that prioritize visible effort over meaningful impact.
In this sense, work addiction is not a personal weakness. It is often a systemic adaptation to dysfunctional performance norms.
Reducing work addiction requires action at three coordinated levels:
- Personal level: Relearning boundaries, recovery rhythms, and somatic awareness. A simple diagnostic question is: Does my work still give me energy, or does it only consume it?
- Managerial level: Communication, openness, trust
- Organizational level: Shifting from fragile hyper-optimization to robust sustainable performance
Ultimately, the opposite of work addiction is not disengagement. It is aligned commitment — a form of performance that allows people to succeed without disappearing from their own lives.
MIND-BODY RESILIENCE
Companies often assume their most competent employees are the most resilient. Yet, it can be argued that ‘competence’ is actually a risk factor for burnout. Why are these ‘engaged perfectionists’ often the ones most at risk, and what can be done to manage this?
The most competent and engaged employees are paradoxically the most vulnerable to burnout, precisely because they combine three risk factors: a high level of self-demand, difficulty saying no or asking for help, and a tendency to absorb collective burden when systems malfunction.
These profiles, which I call “engaged perfectionists,” often compensate for organizational failures — understaffed teams, unrealistic objectives, inefficient processes — by overinvesting their own energy. They thus become the invisible pillars of collective performance, but at the cost of their own balance.
Managing this risk requires both individual and organizational interventions: teaching high performers to recognize early somatic warning signs, creating permission structures where saying no is valued as strategic judgment rather than lack of commitment, and most importantly, addressing the systemic dysfunctions that make overwork necessary in the first place.
Our mind and body are an integrated system. What role does our body — be it fatigue, emotional signals, or nervous system — play in sustaining performance? And what signals can one listen out for?
Long before burnout becomes clinically visible, the body already signals distress through:
• chronic fatigue that doesn’t resolve with rest
• sleep disruption
• persistent irritability or emotional flatness
• loss of meaning or connection to purpose
Listening to the body is therefore not a soft skill, but a core strategic leadership competency. Leaders who systematically ignore these signals, their own or their teams’, unknowingly create the structural conditions for collective burnout. The body speaks in symptoms when boundaries have been violated too long. Learning its language is learning to sustain performance.
COMMUNICATION AS A KEY
You’ve written and spoken extensively about psychological safety, rituals and feedback culture. How can an effective communication environment be designed through the right feedback, psychological safety, and rituals to foster both individual and collective sustainable performance?
Psychological safety becomes tangible when three sentences can be spoken openly in front of one’s manager and senior leadership:
• I don’t know.
• I made a mistake.
• Help me.
Teams characterized by high psychological safety demonstrate greater innovation, learning behavior, and performance². When these sentences are impossible, performance becomes rooted in fear and silence, inevitably leading to disengagement or burnout.
Beyond declarations, psychological safety is built through concrete rituals: moments of collective regulation where the team can name what works and what doesn’t without retaliation, regular feedback centered on learning rather than judgment, and protected spaces where vulnerability is not only tolerated but valued as a sign of lucidity.
These rituals are not cosmetic additions. They are infrastructures of collective resilience that enable teams to navigate uncertainty, failure, and stress without disintegrating. Communication is not information transmission — it is the circulation system through which trust, energy, and meaning flow or become blocked.
SUPPORT AS A STRATEGY
What is the strategic role of organizational leadership in enabling sustainable performance? Beyond the strategies, programs, and surveys, how can organizations develop real supportive and sustainable cultures beyond cosmetics?
The strategic role of leadership in sustainable performance is often misunderstood. Many organizations invest in programs, surveys, or well-being initiatives, yet employees continue to experience exhaustion, disengagement, or loss of meaning. This is because sustainable performance is not created by tools. It is created by what leaders embody, tolerate, and regulate every day.
A supportive culture does not emerge from communication campaigns. It emerges when
three structural signals become visible:
• Leaders model boundaries instead of rewarding overwork
• Mental health becomes a strategic indicator, not a private issue
• Psychological safety is practiced, not proclaimed
Research consistently shows that leadership behavior is the strongest predictor of team well-being and performance. In other words, culture is not what organizations say. It is what leaders repeatedly do under pressure.
Moving beyond cosmetic transformation therefore requires a shift from symbolic care to structural care : embedding recovery, autonomy, and cooperation directly into how work is organized, measured, and rewarded.
WHAT COMES TOMORROW
If an organization, leader, or professional wanted to reorient towards a more sustainable performance model tomorrow: What is the key mindset change they must adopt?
If an organization, leader, or professional wanted to reorient toward sustainable performance tomorrow, two dimensions are essential: mindset and first action.
The fundamental transformation is moving from: “How much can we extract?” to “How long can we sustain?” This implies redefining performance not as maximum intensity, but as durable effectiveness compatible with human health.
What are the first concrete actions they must take to set this change in motion?
Three immediate levers can initiate this shift:
• Measure recovery, not only productivity. What is not measured is never protected.
• Train leaders in emotional and somatic regulation. Sustainable performance begins in the nervous system before it appears in KPIs.
• Create protected spaces for truth-telling where teams can name dysfunction without career risk.
These actions are simple, yet profoundly transformative. Because sustainable performance is not built through complexity, but through consistency over time.
As Gen Z enters workforce decision-maker roles with different boundaries, paving the road to Gen Alpha soon — the old contract of ‘sacrifice now, succeed later’ is breaking. What does the future of ‘ambition’ look like in a sustainable performance model?
The historical contract suggested: sacrifice now, live later. Emerging generations are rewriting it: succeed without losing yourself. This shift is not generational fragility. It is civilizational lucidity. At a time when nearly one worker in two reports psychological distress and disengagement costs organizations hundreds of billions globally each year⁴, sustainable performance is not an ethical option it is an economic necessity.
The ambition of the future will therefore no longer be defined by hierarchy, status, or sacrifice, but by the capacity to create value while preserving life. In that sense, the most powerful leaders of tomorrow will not be those who push harder, but those who make performance compatible with being human.
