The most successful organizations in America don’t necessarily have the smartest strategies, the most advanced technology, or the deepest pockets. What they share is something far more fundamental: their people genuinely care about each other’s success and feel safe enough to bring their best selves to work every day.
This isn’t corporate fluff or feel-good platitudes. It’s a measurable competitive advantage that shows up in everything from innovation rates to customer satisfaction scores. Yet most leaders completely miss it, focusing instead on metrics, processes, and systems while ignoring the human foundation that makes everything else possible.
Simon Sinek’s book Leaders Eat Last reveals why this approach fails so consistently—and more importantly, how leaders can build organizations where people thrive. Through compelling research into human biology, military psychology, and real-world case studies, Sinek demonstrates that the most successful leaders understand something their competitors don’t: business is fundamentally about people, and people perform best when they feel emotionally safe.
The Circle of Safety: Protection That Unleashes Performance
Every organization faces constant external threats: market volatility, technological disruption, competitive pressure, regulatory changes, and economic uncertainty. These dangers are largely beyond our control and will never disappear. But there’s another category of threats that can be far more damaging—the ones that come from within.
Internal threats include office politics, backstabbing colleagues, blame cultures, layoff fears, and leaders who prioritize their own advancement over their team’s wellbeing. Unlike external threats, these internal dangers are completely within leadership’s control. When leaders fail to address them, people waste enormous energy protecting themselves from their own colleagues instead of focusing on external challenges that could actually harm the organization.
Simon Sinek calls the protective environment that great leaders create around their teams the “Circle of Safety.” Just as ancient warriors formed defensive circles with shields facing outward to protect the group from external enemies, effective leaders establish psychological safety that shields their people from internal threats.
The U.S. Marines: Leadership in Its Purest Form
The concept of “leaders eat last” comes directly from the U.S. Marine Corps, where officers literally eat after their troops in the mess hall. This isn’t just military tradition—it’s practical leadership psychology that creates unbreakable bonds between leaders and their people.
Captain William Swenson embodied this principle during a brutal firefight in Afghanistan that earned him the Medal of Honor. When his unit came under intense enemy fire, Swenson repeatedly ran into the kill zone to rescue wounded soldiers and Afghan troops. What’s remarkable isn’t just his individual courage—it’s that his fellow Marines did the same thing, each risking their lives for the others.
This level of sacrifice and mutual support doesn’t happen by accident. It emerges from a culture where leaders consistently demonstrate that their people’s welfare comes before their own comfort, convenience, or career advancement. When team members see their leader genuinely putting their needs first, they naturally reciprocate with extraordinary effort and loyalty.
The Marine Corps understands something that most businesses miss: people will go to extraordinary lengths for leaders they trust, but they’ll do the bare minimum for leaders they fear or distrust. The difference between these two scenarios isn’t just moral—it’s measurably strategic.
When Leadership Fails: A Personal Lesson
Twenty years ago, I witnessed the consequences of leadership that dismantles rather than fosters the Circle of Safety. I worked as a teacher in a middle school under a principal who managed through fear and intimidation. Instead of being transparent about budget challenges, he chose to keep everyone on edge with constant layoff threats.
His daily refrain of “We might have to let some people go” created a toxic environment where teachers focused more energy on looking busy than being effective. Colleagues became competitors rather than collaborators. The quality of education suffered as stressed teachers prioritized job security over student success.
The irony was stark: his attempt to motivate through fear actually cost far more than transparent leadership would have. The constant turnover meant expensive recruitment and training cycles every year. More importantly, it destroyed the passion and creativity that originally drew talented educators to the school.
This experience taught me that when leaders fail to create safety, people naturally create their own protection—usually at the organization’s expense. The principal’s approach didn’t just harm individual wellbeing; it systematically weakened the organization’s capability and performance.
The Chemistry of High-Performance Cultures
Why do some teams naturally collaborate while others fall apart? The answer lies in our biology. Humans evolved with four primary chemicals that drive behavior, and understanding this neurochemical foundation is crucial for building strong organizational cultures.
Endorphins help us push through pain and discomfort, released during physical exertion and stress. They enable perseverance when things get difficult and help teams power through challenging projects and tight deadlines.
Dopamine rewards achievement and goal completion. It creates the satisfaction we feel when checking items off our to-do list or hitting quarterly targets. Dopamine drives individual performance and personal accomplishment.
Most organizations stop here, focusing exclusively on individual performance chemicals while completely ignoring the social ones that actually hold teams together.
Serotonin is the leadership chemical, released when we feel respected, valued, and proud of our accomplishments. More importantly, it’s triggered when others recognize our achievements publicly. Serotonin creates the feelings that make leaders want to serve their people rather than exploit them, and it makes team members want to contribute to collective success.
Oxytocin is the trust chemical, released through physical contact, eye contact, and acts of generosity or kindness. It builds the deep bonds that enable teams to function as unified groups rather than collections of individuals. Oxytocin explains why handshakes matter, why face-to-face meetings often accomplish more than video calls, and why small gestures of caring have such profound impacts on team dynamics.
Barry-Wehmiller: Building Culture Through Crisis
Bob Chapman, CEO of Barry-Wehmiller, demonstrated the power of this neurochemical understanding during the 2008 financial crisis. His manufacturing company faced a brutal reality: they could no longer afford to keep all their employees. For most companies, the solution would seem obvious, if unpleasant—lay off enough people to balance the books.
But Chapman refused to sacrifice people simply because the company was having a difficult year. He had come to see his company as a family, and as he put it, “We would never dream of getting rid of one of our children in hard times.” Instead of layoffs, Chapman implemented a mandatory furlough program where every employee, from CEO to secretary, would take four weeks of unpaid time off.
The way Chapman announced this program revealed his leadership character: “It is better that we all suffer a little, so that none of us has to suffer a lot.” This approach triggered massive releases of serotonin and oxytocin throughout the organization. People felt valued and protected, even during crisis.
The response was extraordinary. Unlike companies that announce layoffs, sending everyone into self-preservation mode, Barry-Wehmiller employees spontaneously began helping each other. Those who could better afford the unpaid time traded shifts with colleagues who needed the income more. Many took additional unpaid time beyond what was required, just to help someone else.
When conditions improved, Chapman not only restored the suspended 401(k) contributions but back-paid them to when the tough times began. The result was intense loyalty and engagement that few organizations ever achieve. People didn’t just work for Barry-Wehmiller; they belonged to it.
The Wedding Revelation
Chapman’s approach crystallized during a wedding he attended. Watching the ceremony unfold, he observed the moment when the bride’s father handed his daughter to her future husband—a symbolic transfer of responsibility for her care and protection.
“It’s exactly the same for a company,” Chapman realized. Every single employee is someone’s son or daughter. Parents work to give their children good lives, good educations, and the lessons they need to grow up happy, confident, and capable of using their talents. Those parents then entrust their children to companies, hoping leaders will exercise the same love and care they have provided.
This insight transformed how Chapman viewed leadership. “It is we, the companies, who are now responsible for these precious lives,” he says. Being a leader means accepting the awesome responsibility of caring for people whose parents have entrusted them to your organization.
The Dehumanization Trap: When People Become Numbers
Modern business culture’s obsession with metrics creates a dangerous tendency to lose sight of the human beings behind the numbers. When leaders focus exclusively on abstract data—revenue targets, efficiency ratings, cost reductions—they often make decisions that optimize short-term metrics while harming the people who actually create long-term value.
This abstraction can lead to devastating consequences, as demonstrated by the tragic case of the Peanut Corporation of America (PCA). Executives at PCA, facing pressure to meet financial targets, knowingly shipped salmonella-contaminated peanut products. They had convinced themselves that numbers were what mattered—cost per unit, delivery schedules, profit margins.
Stewart Parnell, PCA’s president, sent emails complaining that positive salmonella tests were “costing us huge money, causing obviously a huge lapse in time from the time we pick up peanuts until the time we can invoice.” The human impact—nine deaths and hundreds of illnesses—became secondary to financial metrics.
The business consequences were total: PCA went bankrupt, executives faced criminal charges, and the entire industry suffered reputational damage. When leaders lose sight of the people their decisions affect, they often end up destroying the very businesses they’re trying to protect.
Stanley Milgram’s Warning
Psychologist Stanley Milgram’s famous authority experiments in the 1960s revealed that ordinary people will inflict harm on others when they can’t see the human impact of their actions and when they’re following orders from perceived authority figures. Milgram found that 65% of participants would deliver what they believed were potentially lethal electric shocks to strangers simply because a scientist in a lab coat told them to continue.
The participants weren’t sadistic—they were ordinary people who had become separated from the human consequences of their actions. When the “victims” were in another room and the participants couldn’t see or hear their distress, compliance rates soared. But when participants had direct contact with the people they were affecting, most refused to continue.
Modern corporations create similar conditions when they separate decision-makers from the human impact of their choices. When layoffs are reduced to spreadsheet calculations and customer complaints become statistics, leaders lose the emotional feedback that would normally constrain harmful behavior.
Destructive Abundance: How Success Can Become the Enemy
Success can be more dangerous than failure. When organizations become profitable and dominant in their markets, they often develop what Sinek calls “destructive abundance”—the dangerous belief that their success is permanent and their current methods are perfect.
Companies experiencing destructive abundance typically stop investing in their people and start extracting value from them. They cut training programs, reduce benefits, and treat employees as costs rather than assets. They prioritize shareholder returns over stakeholder relationships. Short-term thinking dominates long-term strategy.
This shift is subtle but devastating. The culture that built the organization slowly dies, replaced by a transactional relationship where people show up for paychecks rather than purpose. Innovation declines, customer service suffers, and competitive advantages erode.
The Goldman Sachs Transformation
Goldman Sachs provides a stark example of destructive abundance in action. For decades, the firm built its reputation on a partnership culture where senior leaders felt genuine responsibility for junior employees and clients. The company’s success was built on long-term relationships and careful risk management.
But as Goldman grew and went public, this culture gradually changed. The partnership mentality gave way to a more transactional approach focused on short-term profits. Employees began to feel like expendable resources rather than valued partners. The famous “long-term greedy” philosophy—taking care of clients to ensure long-term prosperity—was replaced by more aggressive short-term extraction.
Greg Smith, a Goldman executive director, captured this transformation in his public resignation letter: “The environment now is as toxic and destructive as I have ever seen it… The firm has veered so far from the place I joined right out of college that I can no longer in good conscience say that I identify with what it stands for.”
When success leads organizations away from the values that created that success in the first place, decline often follows. The culture that once attracted top talent and inspired extraordinary performance becomes the very thing that drives people away.
Trust and Integrity: The Foundation of Everything
Technical skills can be taught. Industry knowledge can be learned. Strategic thinking can be developed. But integrity is foundational—without it, all other leadership qualities become tools that can harm rather than help.
Integrity means consistently doing the right thing even when it’s difficult, expensive, or unpopular. It means being honest about problems, admitting mistakes, and taking responsibility for outcomes beyond your direct control. It means treating all people with respect regardless of their position or usefulness to you.
Leaders with integrity create environments where others can succeed by being their best selves. They don’t need to manipulate, coerce, or intimidate because people willingly follow leaders they trust and respect. This authenticity attracts top talent and inspires the kind of discretionary effort that creates competitive advantages.
The 3M Innovation Culture
3M demonstrates how integrity-based cultures drive long-term performance. The company’s famous “15% time” policy, allowing employees to spend 15% of their work time on personal projects, exists because 3M leadership consistently demonstrates that innovation matters more than short-term efficiency.
Post-it Notes, one of 3M’s most successful products, emerged from an engineer’s “failed” experiment during his 15% time. Spencer Silver was trying to create a super-strong adhesive but instead discovered a weak, pressure-sensitive adhesive that could be easily removed. Traditional metrics-focused management might have classified this as waste and discouraged such “inefficient” experimentation.
Instead, 3M leadership celebrated the discovery and supported its development into one of the company’s most profitable products. This cultural response to “failure” has generated billions in revenue and countless innovations over decades.
The lesson is clear: when leaders consistently demonstrate integrity in how they treat people and handle setbacks, they create cultures where breakthrough innovations become possible.
The Leadership Choice Everyone Can Make
True leadership isn’t reserved for people with corner offices and executive titles. It’s a responsibility that belongs to everyone who cares about their organization’s success and their colleagues’ wellbeing. Every team member can contribute to creating a Circle of Safety through their daily actions and choices.
This democratized view of leadership empowers everyone to make positive differences. You don’t need permission to show genuine care for colleagues. You don’t need authority to share credit for successes or take responsibility for problems. You don’t need a title to model the behaviors you want to see from others.
When everyone accepts responsibility for looking out for others, organizations become remarkably resilient and capable. Problems get solved faster because people address them immediately rather than waiting for someone else to act. Innovation increases because people feel safe to share ideas and take appropriate risks.
Small Actions, Large Impact
Leadership often happens through small, daily choices rather than grand gestures. Checking on a colleague who seems stressed. Speaking up when something doesn’t feel right. Taking time to explain decisions and gather input. Celebrating others’ successes genuinely. Offering help without being asked.
These seemingly minor actions create ripple effects throughout organizations. One person’s kindness inspires another’s generosity. One person’s integrity encourages another’s honesty. One person’s courage enables another’s innovation. Small acts of leadership compound into cultural transformation.
The question isn’t whether you’re in a position to lead—you are. The question is what kind of leader you choose to be through your daily actions. Will you contribute to a Circle of Safety or allow it to remain broken? Will you serve others’ success or focus only on your own advancement?
Building Organizations Worth Belonging To
The most successful organizations of the next decade won’t be those with the smartest technologies or the cleverest strategies. They’ll be the ones where people feel genuinely valued, emotionally safe, and inspired to contribute their best efforts toward shared goals.
Building such cultures requires leaders who understand that their primary job isn’t managing processes or optimizing metrics—it’s serving the people who actually do the work. This service mentality isn’t weakness; it’s the foundation of sustainable competitive advantage.
When leaders consistently demonstrate care for their people’s wellbeing, development, and success, they create environments where extraordinary performance becomes natural. People don’t just comply with expectations; they exceed them because they feel personally invested in collective outcomes.
This approach requires courage because it often conflicts with short-term pressures and conventional business wisdom. It means defending your team when they make honest mistakes. It means sharing credit generously and taking responsibility for failures. It means investing in people’s growth even when it might not pay off immediately.
But leaders who make these choices discover something remarkable: the more they invest in their people’s success, the more their people invest in the organization’s success. This creates positive cycles where everyone wins—employees get meaningful work and growth opportunities, customers receive better products and service, and shareholders benefit from sustainable long-term performance.
The Path Forward: One Choice at a Time
Leadership transformation doesn’t require wholesale organizational change or massive cultural overhauls. It begins with individual choices made by people at every level who decide to put the wellbeing of others ahead of their own immediate convenience.
Start by genuinely caring about the people around you. Learn their names, understand their challenges, and look for opportunities to support their success. When someone makes a mistake, ask “How can we prevent this in the future?” instead of “Who’s responsible?” When someone succeeds, celebrate publicly and share credit generously.
Create psychological safety by admitting your own mistakes openly and encouraging others to bring forward problems without fear of retaliation. Invest time in developing people’s skills and capabilities, even if they might eventually leave for better opportunities. Defend your team members when they’re unfairly criticized and advocate for their needs with senior leadership.
These actions might seem small, but they compound over time into organizational cultures that attract top talent, inspire extraordinary performance, and create sustainable competitive advantages. As Simon Sinek reminds us, true leadership is about doing little things for the good of others, one day at a time.
The choice is yours: Will you be a leader people follow because they have to, or because they want to? Will you extract value from people or invest in their success? Will you contribute to fear or build trust?
Your organization, your colleagues, and your own sense of purpose depend on how you answer these questions through your daily actions. The world needs more leaders who understand that business success flows from human flourishing, not the other way around.
Let us all be the leaders we wish we had.
