This post is for: founders, directors and managers in growing UK SMEs.

You’ll leave with a simple filter for deciding what to address (and how) before small issues become “just how it is here”.

It is not a guide to running formal grievance/disciplinary processes (get advice on specifics if you have a live situation).

This post focuses on: the everyday leadership moments that quietly shape culture - and how to respond in a clear, supportive way without turning everything into a big confrontation.

Quick wins (if you only have 10 minutes)

• Pick one moment from the last two weeks you noticed but didn’t address.

• Decide what you want the team to learn instead: “This is how we work here.”

• Address it early, privately and plainly - one expectation, one next step.

Repeat. Culture changes through consistency, not speeches.

Culture isn’t your values on the website. It’s what happens - and what doesn’t happen - in the everyday moments. The missed opportunity is usually not the big scandal.

It’s the small things leaders let slide:

• A sharp comment that goes unchallenged

• A strong performer getting away with being rude

• A meeting where one person talks over everyone else

• Meetings never starting on time or always overrunning

• A manager quietly ignoring absence patterns

Every time it isn’t addressed, the team learns the real rule:

“This is allowed here.”

Why leaders don't address it (and why that's normal)

Most leaders aren’t avoiding these moments because they don’t care. They’re avoiding them because they’re trying to keep things moving.

It’s usually one (or a few) of these:

• You don’t want to embarrass someone, especially in front of others.

• You’re not sure what to say, so you decide to “deal with it later”.

• You’re busy and it feels too small to spend time on.

• The person is popular or high-performing and you don’t want the fallout.

• You worry it’ll escalate, get emotional or turn into a bigger conversation than it needs to be.

• You’re trying to be kind - and kindness has accidentally become silence.

The problem is: silence teaches the team something too.

Why this matters more in SMEs

In small and growing businesses, culture spreads fast because:

• relationships are close

• behaviours are visible

• leaders’ choices (and silences) are noticed

That can work in your favour - or against you.

The moments that shape culture - without you realising

Here are four common moments that tend to set the tone.

1) How you respond to poor behaviour from high performers

If someone brings in revenue or has a special skillset that you rely on deeply but leaves a trail of stress behind them, the team is watching what you tolerate.

If the message is “Results matter more than respect”, that becomes the culture.

2) How you handle conflict

Avoiding conflict doesn’t keep things calm and balanced.

It usually creates gossip; factions; resentment or passive-aggressive behaviour.

Leaders who address issues early (and fairly) build psychological safety.

3) How you deal with ‘small’ policy breaches

If policies are applied only when it’s convenient, you lose trust.

Fairness doesn’t mean treating everyone the same.

It means:

• being consistent

• explaining your reasoning

• applying standards evenly

4) What you reward (not what you say you value)

You can say you value teamwork, but if you only reward individual heroics, you’ll get individual heroics.

You can say you value wellbeing, but if you praise people who work late every night, you’ll build burnout.

5) Bonus moment: the "silent meeting"

This one is easy to miss. A meeting looks effective, but nobody is saying what they really think. People nod, decisions get “agreed” and then nothing happens afterwards.

If the real conversation is happening in private messages after the meeting (or even during it), you’ve learned something important: people don’t feel comfortable saying it in the room.

You don’t need to force conflict. You just need to make it normal to ask:

“What are we not saying?” or “What’s the concern here?”

The leadership habit that keeps culture healthy

You don’t need to address everything.

But you do need a simple decision filter:

• Is this behaviour aligned with how we want to work?

• If I ignore it, what will the team learn?

• What would ‘clear and kind’ action look like here?

A simple "worth addressing" check

If you’re unsure whether something is worth raising, use this:

It’s probably worth addressing if…

• it’s happened more than once

• it affects other people (time, workload, stress, fairness)

• it undermines a standard you say matters

• you’d hate it becoming normal

• you’d be annoyed if someone did it to you

You’re not looking for perfection. You’re protecting the standards that make work easier and better for everyone.

What ‘addressing it’ actually looks like

Addressing a moment doesn’t mean a big confrontation.

Often it’s a short private conversation; a clear statement of expectations or a quick reset in a meeting.

For example:

“I want to pause there - we don’t speak to each other like that.”

“Let’s make sure everyone gets airtime. I’m going to bring others in.”

“Can we step out for two minutes? I want to discuss how that landed.”

Small interventions. Big impact.

Three ways to do it (without making a song and dance)

1) In the moment (public reset)

One sentence, calm tone, then move on. You’re resetting the standard, not starting a debate.

2) Straight after (two-minute private word)

“Can I share something quickly? When X happened, the impact was Y. Next time, I need Z.”

3) In the next 1:1 (a slightly deeper reset)

Keep it simple: describe what you noticed, tell them the impact that had, explain your expectations, offer support and if necessary set a date to review progress.

The main thing is timing. The earlier you do it, the lighter it feels.

What not to do (so it doesn't turn into a "thing")

A few small traps that make these conversations harder than they need to be:

• Don’t do it via Slack/WhatsApp/email if it’s sensitive (it removes tone and adds risk).

• Don’t stack multiple examples - pick one clear moment.

• Don’t apologise for the standard (“Sorry, but…”). You can be kind without minimising things.

• Don’t have the chat when you’re tired or annoyed. If you need ten minutes to reset, take it.

Don’t wait until you’re frustrated - frustration makes you less clear.

A quick win you can do today

Think back over the last two weeks and ask yourself:

• What did I notice but not address?

• What behaviour is becoming normal that I don’t actually want?

Pick one thing and deal with it this week, while it’s still small.

FAQ

How do I know whether something is “worth” addressing?

Use your own filter from the post: If I ignore it, what will the team learn?

If the answer is “That’s allowed here” - it’s worth addressing. The earlier you do it, the smaller it stays.

What if I’m worried I’ll make it worse by bringing it up?

That’s common, especially if a culture of “keep the peace” has developed. Start small: one private conversation, one clear expectation, one next step. Most situations escalate because nothing was said for too long.

What if the person is a strong performer and I can’t afford to upset them?

If a strong performer is eroding trust, you’re already paying for it - in quiet disengagement, reduced collaboration and stress on others. Addressing it is often what protects performance long-term (including theirs).

Does “addressing it” mean a formal process?

Not usually. Most culture-shaping moments sit well below formal processes. If you’re seeing repeated behaviour, refusal to change or you’re moving into conduct/performance territory, take advice on the specific situation and follow a fair process.

What if I address it once and it happens again?

That’s your cue to move from “moment” to “pattern”. Repeat the expectation, note it and set a review point. Consistency is what changes behaviour - not one perfect conversation.

If you want culture to feel deliberate

If you’re noticing that your culture is cracking - tension, gossip, inconsistent standards - it’s usually not ‘a morale problem’. It’s a leadership clarity problem.
