Challenge the 'hire slow' mantra. Hiring is an intuitive guess, so act quickly. Once a person is in the organization, their performance is a known fact, not a guess. This clarity allows for faster decisions—both in removing underperformers and, crucially, in accelerating the promotion of superstars ahead of standard review cycles.

Leaders struggling with firing decisions should reframe the act as a protective measure for the entire organization. By failing to remove an underperformer or poor cultural fit, a leader is letting one person jeopardize the careers and work environment of everyone else on the team.

Managers often spend disproportionate energy on low-performing employees. The highest-leverage activity is to actively invest in your top performers. Don't just leave them alone because they're doing well; run experiments by giving them bigger, more visible projects to unlock their full potential and create future leaders.

Firing decisions should be a function of both incompetence and business constraint. Not all underperformers are equal priorities. Some are like a "trash can on fire in the driveway"—a problem, but not the company's main bottleneck. Focus firing efforts on roles that are the direct constraint to growth.

When you establish clear boundaries and accountability, employees must make a choice. They either rise to meet the new standards or they leave. This process naturally filters out underperformers and those who prefer low-accountability environments, ultimately strengthening your team.

Keeping an employee in a role where they are failing is a profound disservice. You cannot coach someone into a fundamentally bad fit. The employee isn't growing; they're going backward. A manager's responsibility is to provide direct feedback and, if necessary, 'invite them to build their career elsewhere.'

High-performing CEOs don't hesitate on talent decisions. One mentor's advice was to act immediately the first time you consider firing someone, as indecision only prolongs the inevitable and harms value creation. This counteracts the common tendency for CEOs to be overly loyal or fear disruption.

Keeping B-players doesn't just produce mediocre results; it actively drags down your A-players. Firing the B-players often results in the remaining A-players becoming even more productive, achieving more with a smaller, more expensive-per-head team. The net result is higher output for lower total cost.

A significant portion of profitability issues stems from serving "bad money" customers who are unprofitable or break-even. Firing them eliminates direct losses and frees up time, energy, and resources to better serve your best clients, leading to a direct and immediate improvement in the bottom-line and team morale.
