The Interplay of Human Capital Sustainability Leadership and the Big Five Personality in Explaining Flourishing
This study of 429 employees in Sabah, Malaysia, reveals that while Human Capital Sustainability Leadership directly promotes employee flourishing, the personality trait of conscientiousness uniquely serves as a significant mediating mechanism linking sustainable leadership practices to well-being, whereas other Big Five traits do not.

In the modern workplace, the goal has shifted from simply getting tasks done to ensuring that people actually thrive while they work. This shift rests on a concept called "flourishing," which psychologists describe as a state of optimal well-being where individuals feel a deep sense of purpose, maintain positive relationships, and experience continuous personal growth. It is more than just the absence of stress or sadness; it is the presence of energy, engagement, and meaning. To understand how organizations can foster this state, researchers have turned their attention to leadership. Specifically, they are looking at "human capital sustainability leadership," a style that prioritizes the long-term development and ethical treatment of employees over short-term profits. This approach asks leaders to act with integrity, show genuine care for their teams, and create environments where people feel safe to grow. But a lingering question remains: does a leader's behavior change an employee's inner life directly, or does it work by subtly shifting the employee's personality traits to make them more resilient?
To answer this, a team of researchers from Universiti Malaysia Sabah and the University of Cyberjaya set out to examine the connection between leadership, personality, and well-being among employees in Sabah, Malaysia. They focused on a specific framework of leadership that blends ethical decision-making, mindfulness, and a servant-like dedication to helping others succeed. They also looked at the "Big Five" personality traits, which are widely recognized as the five core dimensions of human character: how outgoing a person is, how cooperative they are, how organized and responsible they are, how open they are to new ideas, and how prone they are to emotional instability. The researchers wanted to know if a supportive leader could actually change these deep-seated personality traits to help an employee flourish, or if the leader simply provides a supportive environment where these traits can shine on their own.
The study involved 429 employees from various public and private organizations in Kota Kinabalu. These participants filled out surveys that measured how they perceived their leaders' behaviors, how they rated their own personality traits, and how much they were flourishing in their lives. The researchers used statistical tools to trace the pathways between these variables, testing whether the personality traits acted as a bridge, carrying the positive effects of leadership over to the employee's well-being. They were particularly interested in whether the leader's influence was a direct force or if it worked indirectly by encouraging employees to become more disciplined, more cooperative, or more emotionally stable.
The results painted a clear and somewhat surprising picture. The study confirmed that human capital sustainability leadership is a powerful driver of employee well-being. Employees who felt their leaders were ethical, mindful, and dedicated to their growth reported significantly higher levels of flourishing. This positive link held true regardless of the specific personality traits the employees possessed. However, when the researchers looked for the "bridge" they had hypothesized, they found that most personality traits did not act as mediators. Traits like being outgoing, cooperative, or open to new experiences were indeed linked to higher well-being, but they did not change in response to leadership in a way that explained the improvement. Similarly, while emotional instability was linked to lower well-being, leadership did not appear to fix this trait directly to create the positive outcome.
There was one notable exception to this pattern. The trait of conscientiousness—characterized by being organized, responsible, self-disciplined, and goal-oriented—emerged as the only personality factor that consistently helped explain the link between leadership and well-being. The data suggested that when leaders practiced sustainable, ethical, and mindful behaviors, they tended to encourage employees to become more conscientious. In turn, this heightened sense of responsibility and self-discipline helped employees flourish. It is as if the leader provides the fertile soil, and the employee's conscientiousness is the specific seed that grows strongest in that environment, translating the leader's support into tangible personal growth. While the other personality traits remained stable and influenced well-being on their own, conscientiousness was the unique mechanism that leadership seemed to activate.
The study concludes that while personality plays a vital role in how well an employee functions, the most effective path to a flourishing workplace is through direct leadership action. Leaders do not need to wait for their employees to change their fundamental nature to see results. Instead, by consistently modeling ethical behavior, showing mindfulness, and serving the needs of their team, leaders create an immediate and powerful positive impact on well-being. The finding that conscientiousness acts as a partial bridge suggests that these leadership styles also help employees cultivate a stronger sense of duty and self-regulation, which further boosts their happiness. Ultimately, the research offers a practical roadmap for organizations: investing in leaders who prioritize the human element of work is not just an ethical choice, but a strategic one that directly builds a healthier, more resilient, and more successful workforce.
