How Culture Dies in Big Companies
Culture does not collapse in large organisations. It erodes. Slowly, quietly, and usually long before anyone in a leadership position names what is happening.
Culture does not collapse in large organisations. It erodes. Slowly, quietly, and usually long before anyone in a leadership position names what is happening. By the time it becomes visible enough to discuss in a board meeting, the damage has been accumulating for years.
I have watched this happen more than once. The organisation that was genuinely different in its early form becomes, over time, indistinguishable from the average. Not through any single decision, but through hundreds of small ones, each of which seemed minor at the time.

The mechanics of erosion
Every organisation starts with something real. A founding group of people who cared about what they were building, who had shared norms, who behaved consistently because they believed in what they were doing. Culture in its early form is not a strategic initiative. It is just the way people who care about something work together.
As organisations grow, that culture has to travel. It has to reach people who were not there at the beginning, who did not experience the founding context, who joined for reasons that may have nothing to do with what the original culture valued. And it has to survive the introduction of formal systems, hierarchies, and the inevitable compromises that come with scale.
This is where the erosion begins. The accumulation of small inconsistencies, individually minor and collectively representing a fundamental change in what the organisation actually is.
Gallup's 2024 State of the Global Workplace report found that only 21% of employees globally are engaged at work, down from 23% the year before, costing the world economy $438 billion in lost productivity. That disengagement does not appear from nowhere. It is the measurable output of cultures that have drifted, one compromise at a time, away from the conditions that make people genuinely want to do good work.
What the signals look like
The first signal is usually the promotion of someone who does not embody the values the organisation claims to hold, but who produces results. The message this sends is heard clearly and remembered at every level: results matter more than values. That is fine as an honest position. Most organisations will not say it honestly.
The second signal is when a values violation is handled quietly rather than clearly. Someone behaves in a way that is inconsistent with what the organisation says it stands for. The response is a private conversation, a quiet performance process, a sideways move. The behaviour is never publicly named as a violation. The team notices. They conclude that the values are negotiable.
The third signal is when the organisation starts measuring the wrong things. When short-term extraction is incentivised over long-term relationship. When individual competition is rewarded in an organisation that claims to value collaboration. When compliance is mistaken for commitment.
SHRM research has found that toxic workplace cultures, often the end state of unchecked culture erosion, cost US companies over $223 billion in a single decade through employee turnover alone. The erosion does not stay cultural. It becomes financial.
The disengagement that precedes departure
There is a stage between an engaged employee and a departed one that most organisations miss entirely. It is the stage where the person has stopped believing the organisation is what it claimed to be, but has not yet made the decision to leave.
In this stage, they are present but not committed. They do what is required to stay employed and nothing more. Their discretionary effort, the extra that distinguishes a good organisation from a mediocre one, goes somewhere else. Into their own development, into a side project, into the kind of careful career planning that ends with a resignation.
Gallup found that in the United States, 17% of employees were actively disengaged at the end of 2024, the highest proportion in a decade. Active disengagement is not passive. Actively disengaged employees are working against the organisation, not just failing to work for it. They share their frustration. They undermine initiatives they disagree with. They accelerate the erosion in the people around them.
Why leadership misses it
Senior leaders in large organisations are often the last people to see culture erosion clearly. They are surrounded by people who manage the information that reaches them. They attend events where culture is performed rather than lived. They read engagement surveys that measure satisfaction, not belonging or genuine commitment.
The organisation reported to them and the organisation that exists for the people doing the daily work are often not the same place.
Manager engagement fell from 30% to 27% in 2024, and then to 22% in 2025 according to Gallup. The managers who are closest to the operational reality, and who could surface culture problems early, are themselves increasingly disengaged. The feedback loop that could catch the erosion is broken before the information reaches the people with the power to act on it.
The leaders who see it clearly are the ones who maintain genuine proximity to the operational reality. Who notice when the conversations change in tone. Who pay attention to who is leaving and pattern-match across the departures. Who make it structurally safe for honest information to reach them, rather than assuming it will do so naturally.
What reversal looks like
Culture erosion does not reverse itself. It reverses when leaders decide to name what has happened and choose different behaviour, consistently, over a long enough period that the organisation recalibrates.
That means acting visibly on the small things. Calling out the contradiction when it is minor, before it becomes a pattern. Making it obvious, through concrete decisions, that the values are not decorative. Promoting people who embody the culture, even when someone with weaker cultural alignment has stronger short-term numbers.
It also means being honest about what the organisation is during the period of repair. Telling people: we have drifted, this is where we are, this is what we are choosing instead. That honesty is not comfortable. But it is more effective than pretending the drift did not happen while asking people to trust a set of values that the recent history has called into question.
Culture does not announce its deterioration. It simply becomes visible one day in the aggregate, when the organisation is already well into the process of becoming something different from what it set out to be. The time to address it is not then. It is in the small moments before, when the cost of acting is still low.
