Last week I had dinner with owners and executives from very different companies. And I confirmed another pattern. Every time we ask about generational challenges, people answer with business issues, and the risk they carry: turnover, exhausted managers, knowledge slipping down the drain, and strategy that isn’t moving at the pace the market demands. Hold on to that idea, because it’s the only one that matters today.

It was at the second B Dinner of the B Corp Community of Madrid, at Infinito Delicias (cracking venue, by the way), an initiative we drive alongside the B Corp volunteer group and Ars Persona. And something happened that doesn’t always happen: people opened up, no posturing, none of the “everything’s going great at my company”. A safe space where we’d all come to think.

Why generational diversity is a business problem, not an HR one

Generational diversity is a business problem because its cost shows up in turnover, lost knowledge and strategy you can’t execute on time, not in a clash of ages.

The metaphor we used that night says it all. Picture a bucket with holes.

If your people keep slipping away and you keep pouring fresh talent in at the top, it’ll keep leaking out through the holes. You can hire non-stop. Doesn’t matter. The bucket keeps losing water, and your company won’t have the capacity it needs to hit the results it set out to achieve.

So our thesis is simple: generational tensions aren’t the cause. They’re the symptom. Of leadership that doesn’t evolve at the pace of the market, of cultures that no longer connect, of misaligned expectations, of organisational models built for a world that no longer exists. Now let me prove it to you with a real story.

How to manage generational diversity in a family business: the case of Grupo Cartés

In a family business, the key isn’t managing ages but redesigning the management model and the connection between generations. That’s how Grupo Cartés lived it.

That same night I heard it told first-hand by one of our most cherished clients. Roberto, of Grupo Cartés, a third-generation family business specialising in filtration and fluid control, shared his own journey with brutal honesty. What used to work on closeness alone, on bar-stool chats and corridor conversations, stopped working when the business grew. The workforce felt that “those at the top didn’t understand those at the bottom”. And his committee had to do “an exercise in humility” and accept that the business wasn’t growing, and that they were right.

See how the symptom looked generational, but the problem was something else? It wasn’t about age. It was leadership, connection, and a management model designed for a company that no longer existed.

What they did next is the best lesson of the night: we brought method where there had only been instinct. And they decided to give the younger ones “one hundred per cent of the support to grow and to crash”, because “if they crash, nothing happens”, with a methodology to measure it in time. When the connection between generations improved, what always happens happened: the veteran’s knowledge started flowing to the youngster, and the youngster’s energy started moving the veteran. They stopped eyeing each other with suspicion and started building together.

“This is all about love”: legacy as the engine of generational handover

That’s how Roberto put it, in those exact words. And he spoke of the purpose of turning his experience “into a legacy through the business”. That legacy took shape when his son Pedro told him “I’m ready to contribute now”. Today Pedro has brought fresh blood, AI included, with his startup Zero Ops, to a business with decades of history.

Generational coexistence, well designed, doesn’t subtract. It multiplies.

What your organisation gains when organisational design works

When organisational design works, turnover falls, knowledge stays in-house, and the real capacity to execute strategy improves. That’s the measurable return.

This is where it stops being a nice HR conversation. When you put numbers on the table, things change. Turnover has a cost, and it’s measurable: every person who leaves takes with them the money you invested in attracting and training them, leaves a mark on those who stay, and a hole someone else has to fill. The knowledge that’s lost doesn’t come back. And the strategy you can’t execute in time, because you don’t have a connected team to do it, has a price too: the opportunities that slip through your fingers.

When you take that cost (and its solution) to a board of directors, you stop being the nice initiative that brings generations together and start solving the bottleneck that’s holding back the plan. Because when the organisation works, age matters less: differences enrich, contribution rises, and so do well-being and the real capacity to execute.

Let’s talk: a diagnosis of where your organisation is losing talent

Generations don’t break anything. They just show you where you were already broken.

So if you’ve got people leaving just when they were starting to contribute, high turnover or burnt-out managers, maybe you don’t need to hire more. Maybe you need to look at the holes in the bucket. If you’d like, I’ll help you analyse it.

Come on, let’s get to it. A big hug.

Frequently asked questions about generational diversity at work

Is generational diversity an HR problem or a business problem?
It’s a business problem. Although it’s usually spotted by HR, its cost is measured in turnover, lost knowledge and strategy that can’t be executed on time, all with a direct impact on the bottom line. Generational tensions aren’t the cause, but the symptom of an organisational model that no longer fits.

Why does young talent leave even when a company keeps hiring?
Because hiring more is useless if the organisation loses its people for the same reasons as always: lack of connection, misaligned expectations, leadership that doesn’t evolve. It’s the “bucket with holes” effect: you can pour fresh talent in at the top, but it’ll keep leaking out unless you repair the holes first.

How do you manage up to four generations working together in one company?
Not by managing ages, but by designing the organisation so that different people connect, understand each other and contribute. When connection works, the veteran’s knowledge flows to the youngster and the youngster’s energy moves the veteran. Age stops being a barrier and becomes an advantage.

How should a family business approach generational handover?
By bringing method where there was only instinct, and giving the new generations real support to develop, even to make mistakes, with a methodology that allows you to measure and support in time. Handover works when it’s framed as a legacy through the business, not just a transfer of power.

What is the real cost of staff turnover?
Every person who leaves takes with them the investment made to attract and train them, leaves a mark on those who stay, and a gap someone else has to fill. Add to that the knowledge that doesn’t come back and the opportunities lost when the team isn’t connected to execute the strategy. It’s a measurable cost, which is why it belongs on the board’s table.
