In the book Software Engineering at Google, a dangerous management fallacy is exposed: the hope that underperformers will quietly leave if ignored. In reality, the opposite happens. While managers avoid difficult conversations to take the path of least resistance, they inadvertently show their best employees the door.

Too many managers believe that underperformers will eventually "self-select" out of the organization. But wishful thinking is not a management strategy.

The Harsh Reality of the Performance Gap

When performance issues are ignored, the weight doesn't vanish; it shifts. High performers are the ones who end up carrying the extra load, leading to a toxic cycle:

  • Burnout Risk: High performers are 34% more likely to burn out when they are constantly forced to compensate for underperforming teammates.
  • Faster Turnover: Top talent leaves 2x faster when they perceive a total lack of accountability for poor performance.

💥 The Backfire Effect

When a manager stays silent about a team member's lack of contribution, the "A-players" don't see a "nice" boss. They see a leadership failure. They begin to interpret the silence through these lenses:

“Excellence clearly doesn’t matter in this culture.”

“I’m working twice as hard for the exact same recognition and pay.”

“Leadership doesn’t have my back when things get difficult.”

The result is predictable: Your stars start updating their resumes and interviewing elsewhere, while your underperformers get comfortable and stay forever.

📖 What Google Actually Says

In Software Engineering at Google, the authors argue that performance must be handled with direct feedback and structured Performance Improvement Plans (PIPs), never wishful thinking.

Google utilizes OKRs (Objectives and Key Results) to create social incentives. Because team scores are public and transparent, it becomes nearly impossible for poor performance to hide. When everyone knows what success looks like, the lack of it becomes obvious to the entire group, creating a natural pressure to either improve or move on.

⚖️ Strategic Solutions for Managers

Addressing underperformance isn't "mean"—it's an act of fairness to those who are doing their jobs well. Here is how to fix the trap:

  • Clear Improvement Plans: Set specific goals with firm deadlines. A PIP should not be a death sentence, but a clear roadmap for what is required to stay.
  • Public Team Metrics: Use transparent metrics that prevent individuals from "hiding" behind the collective output of the team.
  • Quick, Decisive Action: When an improvement plan fails, you must act. Keeping someone in a role they cannot fulfill is a disservice to them and a disaster for the team.

🎯 The Bottom Line

Stop hoping your underperformers will leave on their own. They won't. They have found a place where they can do less and get paid the same.

However, your best people—the ones with the most options—will be the first to walk away. Create a system where poor performance is visible and excellence is the only way to thrive.
