Why Letting Go Is the Hardest, Most Important Hiring Decision

Before ending employment, establish what was expected, what happened, what support was available, and whether the employee understood the concerns. Poor results, a changed role, and serious misconduct require different assessments; dissatisfaction alone does not determine the right action.

The Question Nobody Asks: Is Firing as Important as Hiring?

Every startup accelerator, management book, and founder podcast obsesses over hiring. How to source. How to interview. How to close. But almost nobody talks about the other side of the talent lifecycle: what happens when a hire does not work out.

Ben Horowitz put it bluntly in The Hard Thing About Hard Things: “The hard thing isn’t hiring great people. The hard thing is when those ‘great people’ develop a sense of entitlement and start demanding unreasonable things.” The true test of leadership is not assembling a team. It is maintaining one.

Jim Collins made this explicit in Good to Great. Companies that made the leap didn’t just get the right people on the bus. They first got the wrong people off the bus, then figured out where to drive. Collins warned: “Letting the wrong people hang around is unfair to all the right people, as they inevitably find themselves compensating for the inadequacies of the wrong people. Worse, it can drive away the best people.”

Reed Hastings built Netflix’s entire culture around this principle with the “keeper test.” Managers regularly ask themselves: if this person told me they were leaving, would I fight to keep them? If the answer is anything less than an emphatic yes, the employee receives a generous severance package and is let go. Netflix treats itself as a team, not a family. Families don’t cut members. Teams constantly optimize their roster.

At 37signals, Jason Fried and David Heinemeier Hansson have consistently argued that keeping the wrong person drains the entire team’s motivation. When your brain is constantly navigating friction from a poor fit, you lose the energy to attack large, complex problems. Overall irritability rises. Quality drops.

Tobi Lütke at Shopify has fostered a strict performance culture that rejects the common “compliment sandwich” feedback model in favor of blunt, high-standard evaluations. In Lütke’s framing, work is either “below it or good, great, world-class above it.” There is no credit for hovering near the bar. Tolerating anything below baseline provides zero value to the organization and signals to everyone else that mediocrity is acceptable.

The pattern across these leaders is consistent: hiring builds capacity, but firing protects culture. And culture compounds. A single wrong person can undo years of careful team building in months.

The Hidden Cost of Keeping the Wrong Person

Estimate the costs in your own situation: rework, delayed tasks, additional supervision, recruitment, and onboarding. An unsupported universal $240,000 figure is not a basis for deciding whether to end someone’s employment.

The toxic worker multiplier

Housman and Minor’s Toxic Workers analyzed more than 50,000 workers across 11 firms. It concerned serious misconduct, not merely a personality mismatch. The reported estimates compare avoiding a harmful hire with the additional output of a top performer; they do not guarantee a return from firing a particular employee.

The $12,489 estimate includes turnover and replacement costs in the studied data. It is not a valuation of a person or a general claim that dismissal is always better than improvement. Harvard Business School summary.

The management time drain

Supervisors spend an average of 17% of their time managing poorly performing employees, according to survey data from Robert Half. That is nearly a full day per week. Time spent coaching someone who fundamentally lacks the required skills or values is time stolen from developing top performers, shipping product, and closing deals.

The silent attrition

When the team watches leadership tolerate underperformance, trust evaporates. Patrick Lencioni’s The Five Dysfunctions of a Team traces exactly how this unfolds: once people see that accountability is optional, the entire pyramid collapses. Trust dies first. Then conflict becomes impossible (nobody will say what they actually think). Then commitment disappears. High performers draw an immediate conclusion: standards here are decorative, not real. 95% of CFOs surveyed reported that a poor hiring decision negatively impacts team morale, with 35% stating morale is “greatly affected.” The best people do not complain. They update their LinkedIn and leave.

Record the effects on the team and review them over time. There is no general three-month-delay-to-six-month-recovery formula.

Why We Delay (and Why Delay Is the Real Cruelty)

If the data is this clear, why do smart founders wait? Because firing triggers every psychological defense mechanism we have.

Sunk cost and loss aversion

You spent months sourcing this person. You convinced them to leave a stable job. You invested weeks in onboarding. Letting them go feels like admitting that investment was wasted. Loss aversion, the tendency to prefer avoiding losses over acquiring equivalent gains, keeps managers clinging to a bad situation long past the point where the math demands action.

The “maybe they’ll turn around” cycle

A performance improvement plan should state the expected changes, support, assessment method, and review dates. Do not present it as a genuine opportunity if the decision has already been made. The outcome depends on the situation; an unsupported 15% success rate does not establish that most plans are futile.

Ruinous empathy

Kim Scott’s Radical Candor framework names the exact failure mode. When you care personally about someone but fail to challenge them directly, you fall into “Ruinous Empathy.” Scott describes her own experience keeping a struggling employee far too long out of a desire to be “nice.” The result: she damaged the company’s odds of success, acted unfairly toward the rest of the team carrying the extra load, and was deeply cruel to the employee themselves. Silence did not make her kind. It trapped the employee in a role where they could not succeed, depriving them of the chance to find a job where they could actually thrive.

Delaying a termination is not compassion. It is conflict avoidance wearing compassion’s mask.

Uncertainty about the required process

Employment decisions must follow the requirements applicable to the contract, jurisdiction, and employee’s circumstances. Comparing unrelated average settlement and hiring-cost figures does not establish that legal concerns are irrational. Confirm the grounds, process, documents, and deadlines with the responsible HR or legal adviser.

Seven Indicators It’s Time to Let Go

Generic HR checklists about attendance and KPIs miss the real signals. These seven indicators form an evidence-based framework for the actual decision.

1. The keeper test. Would you enthusiastically rehire this person today, knowing everything you now know? If the answer is “probably not” or “I’m not sure,” you already have your answer. Netflix built an entire culture around this single question.

2. Examine your reaction. Feeling relief at the thought of someone leaving can signal a problem to investigate. It is not by itself a reason to terminate employment.

3. The peer workaround. When top performers start excluding someone from critical projects, building shadow workflows, or taking on double the workload to avoid depending on them, leadership must intervene. The team is already telling you the answer through their actions.

4. Review management time. Record time spent on corrections, support, and conflicts, and consider the causes. The Robert Half figure concerns underperforming employees collectively; it is not 17% of a manager’s week for each individual.

5. Distinguish skills from behavior. A knowledge gap and harmful conduct call for different responses. Describe specific behavior and its impact rather than assume that a person’s values can never change.

6. Stage misalignment. A brilliant Series A hire may not be right for Series B. This is not a performance failure. It is an evolutionary mismatch. As one Y Combinator partner observed: “Probably the number one reason executive hiring fails is because you hire somebody at the wrong stage.” The scrappy builder who thrived in chaos may struggle in a structured, process-driven environment. Recognizing this early and parting ways with appreciation is far better than waiting until frustration turns mutual.

7. Investigate harmful conduct. Take reports of harassment, dishonesty, or other serious harm seriously. Establish the facts and follow the appropriate process. The HBS estimate does not prove a 2.4-times return from any individual dismissal.

How to Do It With Dignity

Executing a termination badly destroys trust with the people who stay. Executing it well builds profound respect for leadership. The details matter enormously.

Timing

The old advice was “fire on Friday.” Modern thinking disagrees. Friday isolates the person for 48 hours with no access to HR for benefits questions, increasing panic and the likelihood of legal action out of desperation. Monday makes them feel they wasted a commute. Tuesday or Wednesday is the optimal window: the person has immediate access to HR, outplacement resources, and the psychological ability to start processing during a normal workweek.

The conversation

Keep it brief, definitive, and free of ambiguity. The decision is final, and the language must reflect that finality. Do not bury the termination between two false compliments. Do not open with “So, how do you think things have been going?” That invites a debate you have already resolved.

Lead with the decision: “We’ve decided to part ways.” Then explain why, factually and without personal blame. Keep the meeting to 15 minutes. The employee needs space to process, not a prolonged justification session that makes the manager feel better about delivering bad news.

Severance and support

Airbnb CEO Brian Chesky set the standard during the company’s 2020 reduction: 14 weeks of base pay plus one week per year of tenure, 12 months of healthcare, the one-year equity cliff dropped for recent hires so everyone left as a vested shareholder, departing employees kept their company-issued laptops to job-search immediately, and an internal “Alumni Placement Team” that published a public talent directory connecting departing staff with hiring managers across the industry.

As Chesky wrote: “Please know this is not your fault. The world will never stop seeking the qualities and talents that you brought.” Patrick Collison at Stripe took a similar approach during their 2022 reduction, with transparent communication and generous severance that preserved trust with the remaining team.

Most startups cannot match Airbnb’s scale. But the philosophy applies at any size: offer the maximum your balance sheet allows, help with the transition, and treat the departure as creating a future advocate rather than an adversary. In tight-knit startup ecosystems where everyone knows everyone, a well-handled separation becomes reputation capital. A badly handled one poisons your employer brand for years.

Communicating to the team

Be honest without violating privacy. The team already knows something was wrong. Acknowledge the change, express respect for the departed person, and reaffirm the standards the team is held to. Silence breeds speculation. A brief, dignified acknowledgment prevents it.

What Happens After: The Recovery Nobody Expects

After a departure, review workload, handover, and whether the original problems have improved. Team performance does not automatically rise within 30 to 60 days.

A departure may remove a source of difficulty, but it can also leave a knowledge gap and additional work. Plan the transition and examine management or organizational problems that a replacement would otherwise inherit.

Review what the company could have done differently in hiring, onboarding, and management. Replacing the employee alone will not resolve unclear expectations or an unrealistic role.

The remaining team draws a powerful conclusion from the decision: leadership takes standards seriously. Excellence is actually required here, not just talked about. That realization deepens trust in management and raises everyone’s commitment.

The gap you feared? It fills faster than you expect. Because the person who was not working out was not just occupying a seat. They were occupying the team’s attention, patience, and goodwill. Clearing that space creates room not just for a replacement, but for everyone else to do their best work.

How Structured Hiring Makes Hard Decisions Easier

The anxiety around firing is almost always a symptom of an unstructured hiring process. When expectations were never clearly defined, evaluating whether someone meets them becomes subjective and emotionally fraught.

This is where the full talent lifecycle matters. When you hire against explicit scorecards and rubrics, starting from a well-defined job description, you create the baseline that makes later evaluation objective. The performance conversation shifts from “I don’t think you’re working out” to “this role requires X capability, which we defined during hiring, and we’re not seeing it in practice.” No ambiguity. No guessing.

When hiring decisions are collaborative, with structured team reviews and documented feedback, the burden of evaluation never falls on one person alone. If things are not working, you have a record of what the team was looking for versus what materialized. The “maybe I’m the only one who sees this” doubt disappears.

And here is the counterintuitive benefit: when you know your organization can course-correct humanely and quickly, you hire more boldly. You take smart risks on non-obvious candidates, the ones with unusual backgrounds or unconventional experience, because you are not paralyzed by the fear of a mistake becoming permanent. The best hires often come from exactly these kinds of bets.

A documented hiring process helps the team revisit its original expectations. Assessment records can inform later conversations, but they do not guarantee a good hire or independently establish grounds for ending employment. Update expectations when the job changes.

Building a great team requires the courage to bring the right people in. It requires equal courage to let the wrong people go. The founders who build the strongest companies are the ones who treat both decisions with the same rigor, the same empathy, and the same urgency.
