Cause #1: Personality Differences

Family Business Makes No Sense — And Here’s Why

Family business makes no sense.

There, I said it.

If you’ve ever worked in one, grown up in one, or tried to manage one, you already know this deep in your bones. The idea of combining family and business sounds wholesome in theory — but in practice, it’s an oxymoron. These two worlds don’t naturally fit together. In fact, they often collide.

I’m John Kenfield, the Family Business Solutionist, based in Melbourne, Australia. I’ve spent decades helping families in business resolve conflicts that threaten to derail both the enterprise and the relationships that hold it together. And after all these years, one truth stands out:

Family business is a crazy environment.

Not because families are bad. Not because business is bad. But because when you mix them, you get a volatile cocktail of emotion, history, expectation, and pressure — all sitting underneath the day‑to‑day operations of a commercial enterprise.

And when that cocktail explodes, I get the call.

Why Family Business Conflict Is So Common

Most families in business eventually find themselves in conflict — often conflict that has been brewing quietly for decades. Childhood dynamics, old resentments, parental behaviour, sibling rivalries, cultural expectations, and emotional baggage all find their way into the boardroom.

When the pressure builds, it doesn’t take much to trigger an eruption. A succession decision. A financial squeeze. An underpaid sibling. An aging parent struggling to let go. A dominant personality pushing too hard. A small catalyst can unleash years of stored frustration.

Families often hope for a quick fix — a magic wand that makes the problem disappear.

But here’s the bad news:

Long‑standing, emotionally rooted conflict does not respond to quick fixes.

To resolve it properly, we have to unpack the problem, identify the root cause, understand why the wheels fell off, and rebuild the system so the train stays on the tracks.

That starts with understanding the people — their personalities, their behaviours, their triggers, and their history.

Which brings us to Cause #1 in my series on the 50 Common Causes of Conflict in Family Business:

 

Cause #1: Personality Differences

Personality is the outward expression of a person’s character — how they think, behave, communicate, and respond in any given situation. It’s a predictor of behaviour.

And in a family business, personality differences are inevitable.

Think of any family you know. The kids can be wildly different — to the point where you wonder how they came from the same parents. Those differences don’t magically disappear when they walk into the business. In fact, they often intensify.

When personality differences clash, you get:

  • Different mindsets
  • Different communication styles
  • Different problem‑solving approaches
  • Different decision‑making processes
  • Different tolerance levels
  • Different emotional triggers

Radically different personalities create radically different behaviours. And if the family hasn’t learned how to leverage diversity, those differences become friction points.

Over time, friction becomes conflict.

Weak Governance Makes Personality Clashes Worse

Many family businesses operate with vague boundaries, unclear roles, undefined authority, and inconsistent discipline. These issues often originate in childhood — weak family governance becomes weak business governance.

Without structure, you get:

  • Confusion
  • Power struggles
  • Low accountability
  • Poor communication
  • And most importantly: low trust

People assume family businesses are high‑trust environments. In reality, many are the opposite. I’ve seen families who believe “everyone has everyone’s back” while, behind the scenes, knives are being sharpened.

Low trust + personality differences = conflict waiting to happen.

Preventing Personality Differences From Becoming Conflict

The best prevention starts long before anyone joins the business.

Parents must raise a team, not competitors.

If children grow up in an ultra‑competitive household, expect that competition to show up in the business — often as dominance, resentment, or sabotage.

If children grow up learning teamwork, shared problem‑solving, and respect for differences, they bring those skills into the business.

Families should intentionally develop:

  • Collaboration
  • Joint decision‑making
  • Appreciation of diversity
  • Emotional intelligence
  • Clear communication
  • Shared responsibility

This builds a strong management team capable of recognising who should lead, who should support, and how to work together effectively.

What if personalities can’t be changed?

They usually can’t.

But behaviours can.

People can learn to recognise how their preferences impact others. They can adjust how they communicate, how they make decisions, and how they handle conflict — even if their core personality remains the same.

This is often the key to resolving long‑standing issues.
