Manager Communication: The Most Important Channel You’re Probably Ignoring

In our last blog, we looked at why two-way internal comms is now non-negotiable, and we included a section on how managers are often the most important -and underused- comms channel! After publishing that blog, we decided that this needed closer inspection and a lot more detail…

‍

So, let’s start with that mildly uncomfortable truth.

‍

Most organisations spend a lot of time perfecting messages for employees… while overlooking (or quietly ignoring?) the one channel employees trust the most. Their manager.

‍

Not the CEO.
Not the intranet.
Not the beautifully designed internal newsletter that took three rounds of approvals and a mild existential crisis to produce.

Their manager.

‍

Research from Gallup consistently shows that employees trust their direct manager more than senior leadership or corporate channels when it comes to workplace communication. In fact, managers account for around 70% of the variance in team engagement.

Which makes the next bit slightly alarming.

Many organisations still treat managers as an afterthought in their communication strategy. They send an all-staff message, attach a PowerPoint for “cascade”, and hope for the best. And then everyone acts surprised when the message lands somewhere between “vaguely understood” and “completely misunderstood”.

‍

Let’s talk about why that happens. And how to fix it.

‍

‍

Why cascade communication so often fails

‍

In theory, cascades are a great idea. Leadership shares information with managers, managers pass it to their teams, and everyone ends up aligned, informed and rowing in the same direction.

In reality, cascades often look more like a game of organisational Chinese whispers.

‍

By the time the message reaches the front line it has been:

• shortened
• reinterpreted
• slightly panicked
• or quietly skipped because the manager didn’t fully understand it either

‍

There are a few reasons cascades fail so frequently.

‍

First, managers are busy people. Very busy people. Often quite stressed busy people. Communication often gets pushed to the bottom of the priority list behind targets, performance reviews, operational fires and whatever new system IT has introduced this week.

‍

Second, most managers are not trained communicators. They were promoted because they’re excellent at their job, not because they know how to translate strategy into meaningful team conversations.

‍

And third, the information they receive often isn’t designed for them in the first place.

‍

Sending a three-page briefing document and expecting managers to magically turn it into a clear team conversation is optimistic at best.

‍

‍

Managers are translators, not postboxes

‍

One of the biggest mistakes organisations make is treating managers as message delivery systems.

‍

Forward the email.
Read out the announcement.
Tick the “cascade complete” box.

‍

But effective managers don’t just deliver messages. They interpret them. They translate strategy into what it means for their team’s daily work. They answer questions. They address concerns. They connect the dots between big-picture goals and practical reality.

‍

Which means internal comms shouldn’t just give managers information. They should give them the tools to have conversations.

‍

What good manager communication support looks like

‍

The organisations that do this well don’t just send managers a slide deck and wish them luck. They provide practical communication support that makes conversations easier.

‍

For example, a good manager communication pack might include:

• a short summary of the announcement
• the three key messages managers need to convey
• answers to likely questions employees might ask
• guidance on what the change means for teams
• suggested conversation starters

‍

In other words, tools that help managers move from broadcasting information to facilitating discussion.

‍

It doesn’t need to be complicated. In fact, simpler is usually better. Managers don’t need a communications thesis. They need clarity.

‍

‍

Talking points are your secret weapon

‍

One of the most effective things internal comms teams can create is a set of manager talking points.

But not a script. Scripts sound robotic and make managers feel like actors in a corporate play they didn’t audition for.

Talking points, on the other hand, give managers confidence while leaving room for natural conversation.

‍

They might include prompts such as:

• What’s changing and why
• What this means for our team specifically
• What stays the same
• What employees might be worried about
• Where people can find more information

‍

The goal is to help managers feel equipped, not constrained.

‍

‍

Training managers to communicate (yes, it matters)

‍

Here’s another slightly awkward truth.

‍

Many managers have never been taught how to communicate effectively with their teams. They’ve had training in budgeting, systems, performance management and compliance. But communication? That’s usually assumed to come naturally.

‍

Unfortunately, it doesn’t.

‍

Research from the Chartered Institute of Personnel and Development (CIPD) highlights that strong line manager communication is one of the biggest drivers of employee engagement and trust in organisations.

‍

Which means investing in manager communication skills is not a “soft” initiative. It’s a strategic one.

‍

Short training sessions on things like:

• explaining change clearly
• handling difficult questions
• facilitating team discussions
• communicating with empathy

can dramatically improve how messages land across the organisation.

‍

And it’s far more effective than simply sending another reminder email.

‍

‍

Campaign thinking works better than one-off announcements

‍

Another reason manager communication gets overlooked is that organisations treat communication as a single moment.

Announcement made.
Email sent.
Job done.

‍

But effective internal communication usually works more like a campaign.

‍

Messages are repeated in different formats. Managers are supported with updates and reminders. Leaders reinforce the message over time. Teams discuss what it means in practice.

Managers are central to this process. They’re the ones who keep messages alive long after the initial announcement has been forgotten by the corporate inbox.

Which is why integrating manager communication into campaign-style internal comms strategies is so powerful.

‍

‍

Leadership messages land differently through managers

‍

There’s also a subtle but important psychological factor at play. When a message comes from senior leadership alone, it can sometimes feel distant or abstract.

‍

When that same message is explained by a trusted manager who understands the team’s work, it suddenly becomes real. Employees can ask questions. They can challenge assumptions. They can see how the message applies to their specific context.

‍

That human translation layer is incredibly valuable. And it’s something no intranet article can replicate.

‍

‍

‍

The internal comms opportunity

‍

For internal comms teams, manager communication is one of the biggest untapped opportunities. Instead of focusing entirely on crafting perfect corporate messages, the real impact often comes from helping managers communicate better.

‍

That might mean:

• building stronger manager toolkits
• embedding communication support into change campaigns
• running manager communication workshops
• providing leaders with better briefing materials
• auditing how information flows through teams

‍

This is exactly the kind of thing that often emerges during a comms health check or strategy review.

When organisations look closely at how messages actually travel internally, they often discover that the missing link isn’t another channel.

It’s empowering the people who already have the most influence.

‍

‍

The bottom line

‍

If employees trust their managers more than any other communication channel - and the evidence (not to mention my personal experience) suggests they do - then manager communication deserves far more attention than it usually gets.

‍

Managers aren’t just message carriers. They’re interpreters, translators and conversation starters. Give them the right tools, guidance and confidence, and internal communication becomes far more effective. Ignore them, and even the best-crafted message can get lost somewhere between the intranet and the coffee machine.

‍

And nobody wants their comms strategy defeated by some stained mugs and a confused middle manager.
