In a recent LinkedIn post, Mark A Odonnell explores the often-overlooked reasons why high-performing employees decide to leave their organizations. Odonnell argues that the departure of great talent is rarely a sudden event, but rather a gradual process that founders frequently fail to anticipate. He emphasizes that the decision to leave is typically the culmination of months, or even years, of accumulating small issues.

Odonnell highlights the subtle nature of these warning signs, noting that employees may continue to perform well and communicate appropriately in meetings even as their dissatisfaction grows. “You don’t see it coming because the signs are subtle. They’re still delivering and saying the right things in meetings,” he writes. By the time an employee submits their notice, Odonnell asserts, the decision has long been made.

The Four Pillars of Employee Discontent

Drawing from his experience across hundreds of companies, Odonnell identifies four primary areas where the breakdown in the employer-employee relationship often begins:

Role Misalignment

One of the most significant factors, according to Odonnell, is the employee being in the wrong role. This isn’t necessarily about a lack of skill, but a fundamental mismatch. He stresses the importance of a “GWC check” – assessing if an employee Gets it, Wants it, or has the Capacity for the role. Furthermore, Odonnell points out the necessity of clearly defining job expectations:

“Nobody ever told them what doing the job well actually looked like. → Define the measurable for every seat. Everyone needs a number they own.”

Stalled Growth and Development

Another critical area is the cessation of professional development. Odonnell observes that employees often leave when they feel they have hit a ceiling with no clear path forward. This lack of progression can stem from a lack of leadership, not just management. As Odonnell states,

“They were managed, but knew they weren’t being led. → LMA starts with leading, not task-tracking. Skip it and their growth stalls with it.”

He suggests proactive measures, such as using the “Quarterly Conversation” to map out future development and career paths, which can include personal growth objectives.

Leadership Deficiencies

Odonnell identifies the direct manager as a frequent source of problems. Issues such as employees not feeling safe to voice concerns until they become critical, or hearing about decisions affecting them belatedly, are key indicators. He advocates for establishing “Issues List discipline” so that employees trust their problems will be addressed. Odonnell also emphasizes the importance of structured communication protocols, like the “Conclude” section of Level 10 Meetings, to ensure timely and appropriate information dissemination.

Eroding Company Culture

Finally, Odonnell points to culture as a significant drain on employee morale. When the stated company values do not align with the actual behavior within the workplace, it can lead to disillusionment. He also criticizes the practice of retaining employees who cause significant damage, suggesting that a “three-strike rule” should be applied consistently. “Delay costs everyone,” he warns, underscoring the negative impact of inaction on the broader team.

In conclusion, Mark A Odonnell’s analysis on LinkedIn provides a framework for understanding the underlying causes of employee turnover. While exit interviews reveal what happened, Odonnell’s “12 reasons” offer a proactive approach to identifying and addressing the ‘why’ before valuable talent walks out the door.
