Company Culture is Not a Poster Hanging on the Wall – It’s Demonstrated by Your Supervisors Every Tuesday at 2 PM

Hanging in the break room right next to the coffee machine is the poster you spent months discussing, debating, and creating: “Respect, Collaboration, Innovation.”
Oddly enough, employees experience company culture when they are not even near the break room but alongside or at the direction of their supervisor.

The Exit Interview

Recently, I heard a story about someone we will call “Sarah”.
Sarah’s exit interview was yesterday. When the HR leader asked Sarah why she was leaving, she pointed to the poster.
  • “Respect? My supervisor talks over me in every meeting and dismisses my ideas without discussion.”
  • “Collaboration? He makes decisions without input and tells us after the fact.”
  • “Innovation? Last week, I suggested a process improvement, and he said, ‘We’ve always done it this way. Don’t fix what isn’t broken.’
Sarah wasn’t angry. She was exhausted. Exhausted by the massive disconnect between the company values poster (and on their website and in every piece of marketing) and her direct supervisor’s daily behaviour.

We have long known that people often don’t leave companies as much as they leave their bosses. That poster cost $47 to print and frame. The replacement hire will cost $30,000. At least.

The value of the knowledge walking out the door is priceless!

Human Resource leaders face similar situations across industries. Sarah’s HR director shared that it was the third exit interview this month with the same theme.  You know that the employee complaint is valid, but it’s hard to document.  Watching engagement scores drop despite leadership’s best intentions is enough to keep you up at night. There is an obvious tension of being caught between frustrated employees and defensive supervisors.
The company is not just losing talent – it is losing credibility.

What 35 Years of Law Enforcement Taught Me

I rose through the ranks without much training on how to actually lead people. You were promoted into a role with the expectation that you were suddenly an ‘expert.’ I never had an official HR title, but humans were all I ever dealt with. I even wrote a book about it.
And here’s what I learned: Direct Supervisors Make or Break Culture
  • Your company values aren’t what you hang on walls. They’re what your supervisors do on Tuesday at 2 PM.
  • Every interaction a supervisor has with their team either reinforces or contradicts their stated values.
  • What tone supervisors use when someone makes a mistake to the way they handle disagreements in meetings. That matters.
  • How supervisors respond to new ideas is important.
  • Do your supervisors protect their team’s time or constantly add to their workload?
  • Will your supervisors show respect when having a difficult conversation?
  • How supervisors offer feedback is key.
  • Can they be trusted to follow through on promises they make?

If you ask an employee about company culture – they think about how they are treated and not by what the website says.

 Culture Initiatives and The Mistakes We Make

We spend thousands on vision statements and culture initiatives and hire consultants to define our values. We roll out engagement surveys and wonder why scores stay flat.  Employee resource groups are created and we celebrate our commitment to inclusion.
But we promote the top performer to supervisor without teaching them how to lead humans.
We assume management skills transfer automatically and hope that good intentions equal good leadership. We send them to a one-day leadership workshop and consider it done.
That’s not a development strategy. Rather, it’s wishful thinking at best.

HR leaders consistently experience:

  • Grievances that one honest conversation could have prevented.
  • Star performers who stop waiting for their manager to invest in them.
  • Teams slowly unraveling because a supervisor would rather absorb the tension than address it.
  • Discrimination complaints that trace back to an unconscious bias nobody wanted to name.
  • The burnout crisis created by managers who don’t understand sustainable workload management.

Human Resources As The Clean Up Crew

If you are an HR leader, you have become the cleanup crew for untrained supervisors. You field complaints and try to repair trust after it’s been damaged. You are the one who watches talented people leave because of poor management.
The gap between your values poster and supervisor reality costs more than money. The disconnect is costing you the culture you’re trying so hard to build.

Supervisors are the Culture of your Organization

Not the leadership team. Not your HR policies. Not your poster.  Culture is demonstrated by your supervisors who:

  • have daily conversations with employees.
  • make the decisions about workload, recognition, and opportunities.
  • directly impact employee retention rate.
  • create the environment where teams either thrive or barely survive.

If you want your values to mean something, teach your supervisors how to live them.

In a recent workshop with supervisors, we spent an entire session on this exact issue.
Each participant considers who were their best and worst bosses and what they learned from that experience.  The impact of those life lessons are ones we never forget.

Values are actions, not pretty words on posters.

One supervisor finally said it out loud: “I’ve walked past that values poster a thousand times. I never once thought about how MY behaviour connects to those words.”
And right there – there is the GAP.

How Can Your Organziation Equip Effective Supervisors?

  • Show supervisors what respectful feedback actually sounds like.
  • Train them on having difficult conversations with empathy.
  • Give them tools to encourage innovation instead of defaulting to “that’s not how we do things.”
  • Help your emerging leaders to understand that their words and actions in small moments create the culture your company claims to value.
  • Teach them to recognize their own biases and blind spots.
  • Give them practical skills for developing their people instead of just managing tasks.
This isn’t about sending supervisors to generic leadership training.
We need to offer supervisors specific skills that align with your organizational values. This is about ongoing development, not one-time events. This is about accountability systems that reward value-driven behaviour.

Leadership Development is Infastructure

Leadership development for supervisors isn’t a nice-to-have. It’s infrastructure. It’s Risk Management
There is a distinct difference between culture by accident and culture by design.
We don’t read about company culture – it’s demonstrated in a thousand small moments every day.

So, don’t hope for the right moments—empower your supervisors to create them. Equip and hold them accountable so every action reflects your culture.

Imagine your organization if every supervisor consistently embodied your core values in every interaction. What begins to shift? What results could you achieve?
Start there.
