The Hidden Cost of Imposter Syndrome: How It Drives Employee Turnover

Employee turnover is a costly problem for global organisations. The loss of top talent disrupts teams, slows productivity, and increases recruitment and training expenses. While many organisations focus on external factors like compensation, career progression, and work-life balance, one of the most overlooked drivers of turnover is imposter syndrome.

Imposter syndrome—the persistent fear of being exposed as a ‘fraud’ despite clear evidence of competence—affects employees at all levels, but it disproportionately impacts high-achievers, women, and underrepresented professionals. Employees who struggle with self-doubt are more likely to undervalue their contributions, experience burnout, and eventually leave their organisations in search of validation elsewhere.

For HR leaders, talent professionals, and business executives, addressing imposter syndrome is not just about supporting individuals—it’s about reducing unnecessary turnover, strengthening leadership pipelines, and fostering a workplace where employees feel confident and committed.

How Imposter Syndrome Contributes to Employee Turnover

1. High Performers Self-Eliminate

Many organisations focus on developing internal talent, yet imposter syndrome causes high-potential employees to opt out of leadership roles and promotions. Employees with imposter syndrome may:

• Avoid career advancement opportunities, believing they are not ‘ready’ despite being qualified.
• Downplay their achievements, making it harder for managers to recognise their contributions.
• Leave before they are ‘found out’, even when their organisation values them highly.

For companies investing in leadership development, losing top talent in this way is a major setback—not just for individuals but for long-term business growth.

2. Burnout and Overworking Lead to Disengagement

Employees struggling with imposter syndrome often work longer hours, overprepare, and take on excessive responsibilities to compensate for perceived inadequacy. While this may seem like a short-term productivity boost, it eventually leads to:

• Burnout—employees mentally and physically exhausted from overwork.
• Decreased engagement—once highly motivated employees becoming disengaged.
• Exit decisions—as employees seek relief in a new job or career change.

According to research, burnout is a leading cause of employee turnover. Addressing imposter syndrome helps prevent overwork, stress, and the loss of high-potential talent.

3. Lack of Psychological Safety Reduces Retention

Psychological safety—the confidence that one can take risks, speak up, and make mistakes without fear of humiliation—is a key factor in employee retention and engagement. However, imposter syndrome makes employees:

• Hesitate to share ideas in meetings, leading to missed contributions.
• Avoid asking for help, fearing they’ll be seen as incompetent.
• Feel like they don’t belong, even in supportive workplaces.

When employees lack psychological safety, they often seek new jobs where they hope to feel more valued. Organisations that foster a culture of psychological safety are more likely to retain and empower their employees.

4. Underrepresented Employees Face Additional Barriers

Imposter syndrome disproportionately affects women, people of colour, and professionals from underrepresented backgrounds—often due to workplace bias, lack of representation, and systemic barriers. These employees may:

• Internalise exclusionary workplace experiences, reinforcing imposter feelings.
• Struggle to find mentors and sponsors, making career progression harder.
• Leave organisations where they don’t feel valued, rather than push through self-doubt.

By actively addressing imposter syndrome through leadership development, sponsorship, and inclusive workplace cultures, organisations can increase retention and advancement for underrepresented talent.

What Organisations Can Do to Reduce Turnover Caused by Imposter Syndrome

1. Train Leaders to Recognise and Address Imposter Syndrome

Managers and senior leaders play a critical role in identifying and supporting employees experiencing imposter syndrome. Organisations should:

• Train leaders to spot imposter syndrome behaviours, such as overworking, perfectionism, and reluctance to take credit.
• Encourage strengths-based feedback, focusing on employees’ achievements rather than vague reassurances like “You should be more confident.”
• Foster open conversations about self-doubt, normalising imposter syndrome as a common challenge that can be overcome.

2. Offer Coaching and Mentorship to Build Confidence

One of the most effective ways to combat imposter syndrome is structured career support. Organisations should invest in:

• Coaching and mentoring programmes to help employees reframe self-doubt.
• Imposter syndrome assessments to help employees identify patterns and build resilience.
• Leadership development initiatives that reinforce confidence and skills.

3. Create a Culture of Psychological Safety

A workplace that encourages openness, vulnerability, and learning from mistakes reduces the impact of imposter syndrome. Organisations can:

• Model vulnerability—leaders sharing their own imposter syndrome experiences.
• Encourage healthy risk-taking and innovation rather than punishing mistakes.
• Prioritise inclusive leadership, ensuring that diverse talent feels seen and supported.

4. Build Stronger Pathways for Career Progression

To prevent high-potential employees from self-selecting out of leadership roles, organisations should:

• Make promotion and progression criteria clear and transparent.
• Actively sponsor talented employees, rather than expecting them to put themselves forward.
• Encourage self-advocacy training, helping employees own their successes.
