When sales managers serve first, salespeople stay longer and sell more confidently

Every year, companies watch some of their best salespeople walk out the door. Voluntary turnover rates for sales professionals range from about 11 percent at large firms to 22 percent at smaller companies, according to industry data. The fallout goes beyond lost revenue. When a skilled salesperson leaves, the company faces higher recruiting and training costs, damaged customer relationships, lower team morale, and weakened brand reputation.

So what keeps good salespeople from quitting? A study published in the Journal of Business-to-Business Marketing investigated whether a particular management style, known as servant leadership, could help. The researchers found that when sales managers adopted servant leadership behaviors, their salespeople reported higher job satisfaction and greater confidence in their own abilities, both of which were linked to lower intentions to leave. But the chain of effects turned out to be more nuanced than a simple cause-and-effect story.

What is servant leadership, and why study it in sales?

Kevin W. Westbrook of Union University and Robert M. Peterson of Northern Illinois University designed the study to fill a gap in the sales research literature. Servant leadership is a management approach in which the leader’s primary focus is on serving the needs of their employees rather than directing them from above. In practical terms, a servant leader asks something like, “What do I need to do to help you succeed?” instead of simply issuing targets and expecting compliance.

The concept, originally outlined by Robert Greenleaf in 1977, includes traits like active listening, empathy, empowerment, humility, and a commitment to helping employees grow. While servant leadership has been studied extensively in other fields like healthcare, education, and the nonprofit sector, Westbrook and Peterson noted that very few published studies had examined it in a business-to-business (B2B) sales context. A search of a major academic database turned up fewer than a dozen articles from recognized sales journals with “servant leadership” in the title or subject heading.

The researchers were particularly interested in a concept called self-efficacy, which is a person’s belief in their own ability to accomplish the tasks their job requires. In a sales context, self-efficacy means a salesperson’s confidence that they can successfully perform selling activities. Prior research had established connections between various leadership styles and self-efficacy, but no one had tested whether servant leadership could boost salesperson self-efficacy and, through that boost, improve outcomes like job satisfaction, sales performance, and the desire to stay with the company.

How the study was designed

The researchers collected data over a 10-day period using an online survey distributed through a commercial survey panel of U.S. sales professionals. All respondents sold products or services to other businesses as part of their job. The final sample included 302 completed surveys from salespeople across a range of industries, including retail trade, services, manufacturing, finance, insurance, and wholesale trade.

The sample was roughly evenly split by gender (53 percent female, 47 percent male) and by company size (about half worked for firms with fewer than 250 employees, and the other half for firms with 250 or more). The average respondent was about 40 years old with nearly 11 years of experience in a sales role.

Respondents answered questions drawn from established academic measurement scales. Servant leadership was measured using an 18-item scale covering five dimensions: empowerment, humility, standing back, stewardship, and authenticity. Self-efficacy was captured with four items assessing confidence in selling ability. Job satisfaction, sales performance, and turnover intentions were each measured with their own multi-item scales. The researchers also measured two types of workplace stress: challenge stressors (like time pressure and high workloads that can push a salesperson to improve) and hindrance stressors (like office politics, unclear expectations, and red tape that can hold a salesperson back).

To analyze the data, Westbrook and Peterson used a statistical tool called Hayes PROCESS, which allowed them to test not only direct relationships between variables but also chains of relationships where one variable influences another, which in turn influences a third. They used 5,000 bootstrap iterations with 95 percent confidence intervals, a standard approach for testing these types of sequential paths.

What the data showed

The analysis revealed several clear patterns. First, servant leadership was directly and positively linked to both job satisfaction and self-efficacy among the salespeople surveyed. Sales professionals who perceived their managers as servant leaders tended to report higher satisfaction with their jobs and greater confidence in their selling abilities. Servant leadership was also directly linked to lower turnover intentions, meaning salespeople with servant-style managers were less inclined to think about quitting.

However, one result stood out as unexpected. Servant leadership had no direct statistical link to sales performance. In other words, simply having a servant leader as a manager was not, on its own, associated with better self-reported sales numbers. Instead, the relationship between servant leadership and performance ran through self-efficacy. Servant leadership was linked to higher self-efficacy, and higher self-efficacy was linked to better performance. This means the connection was indirect: servant leadership appeared to boost a salesperson’s confidence, and that confidence was then associated with stronger sales results. The researchers suggested that self-efficacy may actually suppress or absorb the direct connection between servant leadership and performance, leaving the indirect path as the primary route.

The study also uncovered an interesting twist regarding high performers. While higher job satisfaction was linked to lower turnover intentions (as expected), higher performance was actually linked to higher turnover intentions. This suggests that top-performing salespeople may be more inclined to consider leaving, possibly because they believe they could find better compensation, growth opportunities, or recognition elsewhere. The data was collected during a period of strong economic growth in the United States, when available sales jobs were plentiful, which the researchers noted could help explain this pattern.

Gender and company size did not change the picture

The researchers also tested whether gender or the size of the employer changed any of these relationships. Neither did. The links between servant leadership, self-efficacy, job satisfaction, performance, and turnover intentions held regardless of whether the salesperson was male or female and regardless of whether they worked for a smaller or larger company. This ran counter to some earlier research suggesting that women tend to value relationship-oriented leadership more than men, and that smaller firms tend to foster more employee-centered management styles.

Workplace stress matters, but only up to a point

The picture changed, however, when workplace stress entered the equation. At low and moderate levels of both challenge stressors and hindrance stressors, servant leadership behaviors appeared to buffer the negative effects of that stress on the chain running from self-efficacy to job satisfaction to turnover intentions. In plain language, when salespeople faced manageable amounts of time pressure, workload, office politics, or unclear expectations, having a servant leader as a manager seemed to help cushion the blow.

But at high levels of stress, this buffering effect disappeared. When challenge or hindrance stressors were intense, servant leadership behaviors no longer appeared to protect against their negative impact. This suggests there may be a ceiling on what a supportive management style can accomplish when the work environment becomes extremely demanding or dysfunctional.

Practical takeaways for sales organizations

For business leaders, these findings carry several actionable points. Sales organizations looking to reduce turnover should consider training their sales managers in servant leadership behaviors. The data suggests that this approach is linked to higher job satisfaction among salespeople, which in turn is linked to a reduced desire to leave. This relationship appeared consistent across genders and company sizes, which means it may be broadly applicable.

At the same time, companies should recognize that servant leadership alone may not directly improve sales numbers. The study suggests that the pathway to better performance runs through building salesperson confidence. Training programs that combine servant leadership development for managers with self-efficacy-building activities for salespeople could potentially address both retention and performance simultaneously.

The finding that top performers are more likely to consider leaving deserves special attention. Companies may need to create targeted retention strategies for their highest producers, such as competitive compensation packages, clear paths for career advancement, and meaningful recognition programs. Simply being a supportive manager may not be enough if high performers see better opportunities elsewhere.

Finally, the stress-buffering findings suggest that servant leadership is most effective in environments where stress levels are manageable. In extremely high-pressure sales environments, organizations may need to address the sources of stress directly, through structural or policy changes, rather than relying solely on leadership style to absorb the impact.

Important caveats to keep in mind

This study used self-reported data from a single online survey panel at one point in time. That means the findings describe statistical associations, not proven cause-and-effect relationships. Salespeople who are already satisfied or confident may perceive their managers more favorably, for example. The researchers also acknowledged that different sales contexts, industries, and organizational cultures might produce different results. The study did not measure whether the selling environment was stable or turbulent, which could influence how salespeople respond to different leadership styles.

Additionally, the sample represented a broad cross-section of industries rather than a deep dive into any single one. While this improves generalizability in some respects, it also means the findings may not perfectly apply to every specific sales setting. The researchers called for future studies to continue testing these relationships in different contexts and to examine additional variables that might influence the connection between servant leadership and sales outcomes.
