How to Fix a Toxic Work Culture Without Making It Worse
Research from MIT Sloan found that toxic culture is over 10 times more likely to drive employees to quit
The problem with toxic work cultures isn’t just that they exist; it’s that most attempts to fix them fail. Worse, some interventions actually make things deteriorate further. Research from MIT Sloan found that toxic culture is over 10 times more likely to drive employees to quit than low pay, making it one of the most pressing issues facing organisations today. Yet many leaders admit they don’t know where to start when addressing cultural problems.
The stakes are high. Get it wrong, and you’ll breed cynicism, erode trust, and accelerate the very dysfunction you’re trying to eliminate. But understanding the psychology behind how to fix toxic work culture can help you avoid the common pitfalls that turn well-intentioned efforts into exercises in futility.
Why Culture Change Efforts Backfire
The first mistake leaders make is treating culture as a surface-level problem. Attempting team-building activities with broken teams can quickly backfire when trust is lacking and resentment is high. A day of forced fun doesn’t heal deep wounds; it highlights them. Everyone can see who’s checked out, who’s guarded, and who’s seething beneath a smile.
Another common error is the “survey and ignore” approach. One of the most common complaints is that management administers survey after survey but never acts on the feedback it receives. This breeds profound cynicism. Employees who take the time to share honest feedback, only to see nothing change, learn that their voices don’t matter. The next time you ask, they won’t bother responding—or they’ll actively mistrust the process.
Perhaps most damaging is when leaders fail to acknowledge their own role in creating or perpetuating toxicity. Office culture doesn’t turn toxic because of a few bad seeds. It turns toxic because leadership didn’t see or outright ignored the signs that something was amiss. When those at the top refuse to look in the mirror, any effort to fix toxic work culture becomes theatre rather than transformation.
The Foundation: Psychological Safety
Research from Google’s Project Aristotle found that psychological safety (helping people feel comfortable giving their opinion, taking risks, challenging each other, and asking for help) has the biggest impact on team effectiveness. Without it, no other cultural improvements can take root.
Harvard Business School professor Amy Edmondson, who pioneered research on psychological safety, defines it as the belief that you can speak up with ideas, questions, concerns, or mistakes without fear of repercussions. As she notes, “What that really means is I can do my job without fear of humiliation or punishment.”
Psychological safety doesn’t mean creating a soft environment where everyone agrees. It means establishing conditions where people can speak uncomfortable truths without fear of humiliation or retaliation. Gary Chapman, author of “Rising Above a Toxic Workplace”, captures this reality: “When a workplace becomes toxic, its poison spreads beyond its walls and into the lives of its workers and their families.” A toxic work environment is one where negative behaviours make people feel they’ll be punished, rejected, or humiliated for speaking up, whether to share ideas, raise concerns, or show up authentically.
The absence of psychological safety creates a vicious cycle. People stay silent about problems, which allows those problems to fester and multiply. Stress accumulates. Trust erodes. Eventually, the best people leave, taking institutional knowledge with them.
What Actually Works: Evidence-Based Interventions
Understanding how to fix toxic work culture requires moving beyond quick fixes and implementing strategies grounded in research. Here’s what actually works:
Start with radical honesty about the problem. The first step in fixing a toxic culture is admitting it exists – explicitly and without euphemism. Leaders must avoid saying there are no issues. They should come out and say, ‘Yes, our culture needs change’. This honesty signals that change is possible and that leadership takes the problem seriously.
Model the behaviour you want to see. Research suggests leaders must frame work as a learning problem rather than an execution problem, acknowledge their own fallibility, and model curiosity by asking lots of questions. Organisational psychologist Adam Grant emphasises this point: “Good leaders build products. Great leaders build cultures. Good leaders deliver results. Great leaders develop people.” When leaders admit mistakes openly, apologise genuinely, and demonstrate vulnerability, they give permission for others to do the same. This breaks down the culture of perfection that often underpins toxicity.
Listen properly—then act on what you hear. Employees will not provide candid feedback if they fear that managers can figure out who said what and retaliate for negative comments. Guarantee anonymity, protect people from retribution, and then (crucially) take visible action based on what you learn. Communication must be two-way, not performative.
Address specific behaviours, not personalities. Feeling disrespected at work has the largest negative impact on an employee’s overall rating of their corporate culture. Focus interventions on observable behaviours: interrupting colleagues, taking credit for others’ work, or excluding people from important conversations. Make it clear which behaviours are unacceptable and consistently enforce consequences.
Create structures that sustain change. One-off initiatives won’t cut it. Regular check-ins provide a platform for managers to understand employee challenges, motivations, and stressors, contributing to a healthier employee-manager relationship. Build feedback loops, establish clear values, and embed these into every process, from hiring to performance reviews to promotion decisions.
The Long Game
The reality is that learning how to fix toxic work culture is not a quick fix. Observers say companies working on rehabilitating cultural problems have a long way to go, demonstrating that fixing a broken culture takes commitment over time. The work requires sustained attention, consistent messaging, and the courage to make difficult decisions when individuals refuse to change.
But the alternative doing nothing carries far greater costs. Turnover due to bad work cultures has cost American businesses $223 billion over the last five years. Beyond the financial toll, toxic cultures destroy innovation, crush morale, and damage people’s health.
The path forward starts with acknowledging uncomfortable truths, modelling the behaviour you want to see, and demonstrating through consistent action that change is real. It requires treating culture not as a soft concern but as the foundation upon which everything else is built. Because in the end, culture isn’t what you say. It’s what you tolerate, reward, and model every single day.
