What Is People Sustainability?

It recognises that long-term business performance depends not only on attracting the right talent, but also on creating the conditions for people to perform sustainably throughout their working lives.

That’s the definition. Here’s what it means when you’re the one running the business.

Why does it need a name?

Most companies already measure their money, their stock and their customers very closely. They know their cash position this morning. They know which product line slipped last quarter. But ask how much it cost them to lose their best people last year, and the room goes quiet.

That’s not because leaders don’t care. It’s because the cost is spread across lots of places. Some of it sits in hiring fees. Some sits in overtime, sick days and the weeks a role stays empty. Some of it never shows up anywhere, like the manager who stops putting ideas forward because nothing ever changes.

People Sustainability is just a way of putting all of that in one place, so you can see it and do something about it. You can’t fix what you can’t see.

What does it actually cover?

Look, it’s not a new word for wellbeing. Wellbeing is part of it, but it’s one part.

People Sustainability looks at three things together. Can you keep the people you need? Can they keep doing good work without burning out? And are your leaders building people up, or slowly wearing them down?

When those three hold, the business gets the output it’s paying for, year after year. When they don’t, you pay twice. Once in salary, and again in turnover, absence and work that only gets half done.

What does the research say?

• Low engagement cost the world economy approximately $10 trillion in lost productivity in 2025, about 9% of global GDP (Gallup, State of the Global Workplace 2026).
• Replacing one employee who leaves typically costs half to two times their annual salary (Gallup, 2019).
• A toxic culture is 10.4 times more powerful than pay at predicting who leaves, based on 34 million online profiles of US employees (MIT Sloan Management Review, 2022).

Put those side by side and the picture is pretty clear. The biggest people costs aren’t in the payroll line. They’re in what happens to people after you’ve hired them.

Why does it matter in Vietnam and across Southeast Asia?

Growth here has been fast, and fast growth is hard on people. Managers get promoted because they were good at the job, not because anyone taught them how to lead a team. Good people get poached by the company down the road for a bit more money. And a lot of firms are now bringing in AI and automation on top of all that.

And here’s the interesting bit. In Vietnam, only 13% of employees report daily stress, against 25% across Southeast Asia and 40% globally, and 59% say they’re thriving in life. But just 9% are engaged at work, against 25% across the region (Gallup, Vietnam country data, 2026 report). So people are doing fine in their lives and checked out at work. A stress survey on its own would never show you that.

None of this is a reason to slow down. It’s a reason to know what’s going on underneath the numbers before it turns into resignations, absence or a team that’s stopped trying.

Is it the organisation’s job or the person’s?

Honestly, it’s both, and that’s where most approaches fall down.

Some programmes only look at the person. More resilience training, another app, a talk on sleep. That helps a bit, but it doesn’t fix a manager who never listens or a team that’s been understaffed for a year.

Other approaches only look at the organisation. New policies, new structures, a new survey. That misses the fact that every number on the dashboard is a human being with their own pressures at home and at work.

People Sustainability works both sides. The organisation has to build conditions where people can do good work. And the people inside it need the skills and the support to look after their own energy, health and focus. You need both, or the gains don’t last.

How do you put it into practice?

We use a simple three-step approach.

Identify. Find out where pressure is building and what it’s costing you, team by team. Not a guess, and not last year’s engagement survey.

Develop. Build the leadership and people skills that fix the cause. That might be managers learning to have honest conversations, or a team getting clearer priorities.

Sustain. Make it part of how the business runs, then measure again to see what changed.

Most organisations jump straight to Develop. They buy training before they know what the problem is. That’s like a doctor handing out medicine before asking where it hurts.
