When Informal Power Overrides Authority
Company culture forms through repeated behavior, not written policy. What leaders tolerate becomes the standard, regardless of what the handbook says.
CEO Brief: SHRM found that one in five Americans has left a job in the past five years due to bad company culture, costing U.S. employers an estimated $223 billion in turnover (SHRM, 2019). That figure doesn't measure what was tolerated. It measures what happened after. By the time the exits begin, the informal norms that drove them have usually been in place for years.
Why Does What You Tolerate Become the Culture?
Org charts define authority. Culture is defined by something else: what actually happens, repeatedly, without consequence. When a leader overlooks behavior once, then again, then routinely, the organization stops reading the policy and starts reading the pattern. The pattern is what sticks.
Informal norms don't form through intention. They form through accumulated tolerance. The team that always interrupts in meetings. The executive whose aggressive style goes unremarked. The dynamic between two colleagues that everyone knows about and no one addresses. Gradually, those patterns stop feeling like exceptions. They become what normal looks like here.
CultureX and MIT Sloan Management Review research found that a toxic culture is 10 times more predictive of attrition than compensation (MIT Sloan Management Review, 2022). Employees aren't primarily leaving over pay. They're leaving over what got normalized, over what the leader decided, consciously or not, to let stand.
Informal norms rarely announce themselves as problems. A pattern that developed gradually just becomes how things are done here, until the consequences surface in a way that's hard to ignore.
What Does It Look Like When Informal Norms Have Already Taken Hold?
The signals tend to arrive in clusters. A policy exists but isn't applied consistently. Someone's behavior is known across the organization, but the conversation about it stays informal. Leaders feel uneasy addressing a pattern they've been part of allowing. The line between personal loyalty and professional accountability gets blurry.
Watch for:
Leaders realize they've been tolerating behavior they wouldn't accept from others
Policies exist but aren't consistently enforced
Concerns about workplace safety or professionalism surface suddenly
Leaders feel unsure how to address patterns they've previously ignored
The line between personal loyalty and professional accountability becomes unclear
Research by Christine Porath and Christine Pearson, published in Harvard Business Review, found that when employees experience workplace incivility, 80% lose work time worrying about the incident, and 78% say their commitment to the organization declines (HBR, 2013). These aren't people who haven't noticed. They've noticed, and they've concluded, from what they observe, that the organization doesn't plan to do anything about it.
That conclusion forms gradually. Someone sees a pattern go unchallenged once, then again. By the time it's visible to everyone, it has already been normalized, including by the leader's silence.
How Do You Change a Norm the Organization Has Already Accepted?
Before reaching for a policy update or an all-hands communication, the more useful question is: how did this become normal here, and what has kept it in place? The answer is usually some combination of who tolerated it, for how long, and what it would have cost to challenge it earlier.
Gallup research found that managers account for 70% of the variance in employee engagement (Gallup). The same is true of norms. When a manager looks the other way, when a CEO doesn't name a pattern that's visible to everyone, those aren't neutral positions. Inaction teaches. The organization is always watching.
What policies can't provide is an explicit acknowledgment that something was allowed to happen, followed by visible behavior change at the top. A new rule doesn't reset what people observed for the previous two years. A leader who names what happened and then demonstrates something different starts to shift it.
That's harder than it sounds because it requires accepting some accountability for what was allowed. Call it a factual observation rather than self-criticism: "We let this happen" is the necessary precursor to "we're doing something different." Organizations that skip the first part tend to get symbolic policy changes that don't land, because everyone can see the gap between what's being announced and what the leaders actually modeled.
3Peak Wisdom
Boundaries become real when they're practiced, not when they're documented. The hard part isn't writing the policy, it's acknowledging that something was normalized that shouldn't have been, and then consistently reinforcing new expectations through action.
Structure matters because it makes expectations visible. But structure only works when leaders are willing to uphold it, especially when doing so creates discomfort.

Frequently Asked Questions
How do you tell the difference between an informal norm and a one-off incident?
Frequency and silence. A one-off incident happens and gets addressed. An informal norm is a pattern that repeats without consequence. If something has happened more than once without a clear response, the question worth asking is what message that non-response has sent. That message is what people have absorbed.
Is writing a new policy a useful step at all?
Sometimes, but only if behavior changes alongside it. A policy without visible enforcement signals the opposite of its intent. The organization reads the gap between what's written and what's enforced as information about what leadership actually thinks. If the policy isn't backed by consistent action, it often makes things worse by confirming that the written rules don't matter.
What does accountability actually look like here?
It looks like naming the pattern directly, with the person involved and often with the team, and being clear about what changes. Not a line item on a performance review. An explicit conversation that establishes what was happening and what's expected going forward. The discomfort of that conversation is part of what makes it work. A comfortable exchange rarely resets a norm.
How do you address a norm you yourself helped establish?
Directly. A leader who says "I've tolerated something I shouldn't have, and I want to be clear about what we're changing" creates more trust than one who announces a new policy without acknowledging what created the need for it. That kind of admission doesn't cost you authority. It usually builds it.
What if the person at the center of the norm is a high performer or someone with strong relationships?
Then the calculation is real and has to be made consciously. An organization that sees a norm enforced selectively, only when it's easy rather than when it costs something, learns that the standard is conditional. Selective enforcement is itself a message. High performance doesn't create exemption from behavioral accountability. It just makes the decision harder.
