Let’s be honest: Culture doesn’t fall apart in one big blow-up.

It unravels in the quiet chaos—

• The Slack scavenger hunts.
• The rollout email nobody read.
• The moment someone says, “Wait, is this the final version?”

That’s when people stop asking questions. 

Assumptions sneak in.
Alignment slips. 

Culture cracks and performance tanks.

Most culture problems aren’t people problems.
They’re communication problems.

Which means comms leaders are uniquely positioned to fix them—if you’re willing to step into the gap.

This isn’t about sending prettier emails or polishing slide decks.
It’s about creating the systems, structure, and clarity that fuel trust and high performance across every level of the organization.

Here’s how to lead that charge.

1. Be the Source of Truth Your Organization’s Missing

If your company doesn’t have a central, trusted place where teams can go to get clear, current information, you can build it.

A “source of truth” isn’t fancy. It’s functional. It’s the go-to hub where the “what, why, and how” of your business lives. Think:

• Project updates
• Priorities
• Decisions
• Roles
• FAQs
  

This is where Comms can shine. Don’t wait to be asked—create it.

Start small and simple. Open a shared doc or spreadsheet or create a drive folder.  Label it clearly: “Team Source of Truth.”  Add these three sections: 

That’s it.
Three headers.
One page.
Updated weekly or biweekly.

It doesn’t need to be pretty (although I do love great branding!), It just needs to be trusted.

Once it’s live, share it with department leads and say:

“This is a living doc to help everyone stay aligned. Add to it. Flag gaps. Let’s build this together.”

If you take the first step, others will follow.
Because what they really want isn’t more updates—it’s one place to find the right ones. And you just gave it to them.

Even better? Embed a Comms team member into major initiatives so you’re inside the process, not chasing it down later. That’s how you catch misalignment before it hits the front lines.

2. Create a Communication Rhythm People Can Count On

Comms doesn’t just broadcast messages.
You create calm in the chaos.

A predictable communication rhythm helps teams stop spinning. It tells people:

• What to expect
• When to expect it
• Where to go for answers

That’s culture work. And you can lead it.

Here’s a rhythm you can help implement or coach others to adopt:

• Daily async check-ins or team huddles
• Midweek 1:1s or team syncs to surface confusion early
• Friday wrap-ups to highlight wins and prep for next week
• Monthly “state of the team” updates with wins, priorities, and Q&A
• Quarterly strategy + culture pulse reviews

You don’t have to lead every meeting, but you can help design the rhythm, coach the cadence, and keep it consistent.

3. Assign Ownership (and Stop Letting Things Fall Through the Cracks)

“Communication is everyone’s job” is a nice idea, but without clear ownership, it’s nobody’s job.

As a Comms leader, you can fix this by assigning (or helping assign):

• Who updates the source of truth
• Who owns the message before it goes out
• Who follows up on team-wide updates
• Who gathers feedback and closes the loop

Want to elevate your team’s role in the business? Take the lead here. Build the template. Facilitate the flow. And advocate for clear communication roles on every project.

Why This Matters Now

Cross-functional collaboration is where culture breaks—or breaks through.

Too often, department heads roll out initiatives in silos. The Home Office launches something with no input from the people who have to execute it. The gap widens. Confusion grows. And guess who gets caught in the middle?

The team. The frontline. The “little guy” who just wants to do their job but doesn’t have the right version of the info.

You can stop this before it starts.

As a Comms leader, you have permission—and responsibility—to speak up:

• Ask the hard questions.
• Flag the missing details.
• Clarify before chaos.
• Write the message that brings it all together.
  

And when you do? You become more than the messenger.
You become the architect of alignment.

If you’re tired of being left out of the room where decisions happen, build a doorway.
If you want your team to be seen as strategic, act like it.
If you want culture to scale with your business, lead the way.

Start here:

• Source of Truth: Don’t just find it. Be it.
• Communication Rhythm: Predictability beats perfection.
• Ownership: If it’s unclear, clarify it. Then document it.

Culture isn’t a vibe.
It’s the system you build through communication.
And when you build it well, your people feel it everywhere.
