Why workplace burnout isn’t a perks problem, it’s a nervous system one

There’s a number doing the rounds in the workplace reports this year, and it’s hard to look away from. $2.9 trillion. That’s roughly what voluntary turnover is costing companies globally every year.

To put that into perspective, that’s more than the entire GDP of the UK. And it’s the price tag on people walking out the door, often quietly, often from the best teams, often without a clear reason on their exit form. We can keep blaming “the market.” We can keep talking about flexible working and four-day weeks and free meditation apps. But there’s a quieter conversation underneath all of it that most leadership teams aren’t ready to have yet.

It’s about the nervous system. And it’s the reason your wellbeing budget probably isn’t working as hard as you’d hoped.

What the numbers are really telling us

Let’s set the scene properly, because the data this year is genuinely striking.

• Global employee engagement has fallen to 21%, the sharpest drop since the pandemic (Gallup, 2025).
• 40% of global employees report feeling stress “a lot of the day.”
• 77% of workers have experienced burnout at their current job. 83% are sitting in some degree of burnout right now.
• Workplace stress drives around 40% of US employee turnover.
• And here’s the one that quietly does the most damage: 71% of voluntary exits trace back to poor management, not pay.

So no, it isn’t really about the salary. It isn’t really about the snacks in the kitchen. People are leaving because something in the day to day feels unsafe, unsustainable, or just plain depleting. And their bodies are picking it up long before their LinkedIn profiles do.

The bit nobody is naming

When we talk about workplace stress, we usually talk about it like it’s a mindset issue. “Build resilience.” “Manage your time better.” “Just take a holiday.”

But stress doesn’t live in the mind. It lives in the body. In the jaw that won’t unclench. The shoulders that have crept up to the ears. The 3am wake up that you can’t explain. The sigh that comes out before you’ve even opened your laptop.

That’s a nervous system in fight, flight, freeze, or fawn. And when an entire team is operating in that state, day after day, week after week, you don’t get a high performing culture. You get a tired one. A reactive one. A team where great people start to feel a bit numb, then a bit resentful, then a bit done.

This is why so many wellbeing initiatives fall flat. A lunchtime yoga class is lovely, but if the rest of the week is spent in a low grade state of threat, the body doesn’t get the memo. The nervous system stays stuck.

What actually shifts the dial

This is the work I do with corporate teams as a nervous system facilitator. And to be clear, it’s not woo. It’s grounded, practical, and very much measurable in the way people show up afterwards.

Here’s what it tends to look like in a workplace setting:

• Real, accessible practices that can be done at a desk in two minutes. Not “go on a retreat to fix yourself,” but small, sustainable resets people can actually do in a meeting room or on a Tuesday afternoon.
• Education on the body’s stress response so leaders and teams understand what’s happening to them. The shame around “why can’t I just push through?” tends to lift the moment people understand they’re not broken, they’re just dysregulated.
• Co-regulation skills for managers. If 71% of resignations are tied to management, then giving managers the tools to settle their own systems (and therefore the room they walk into) is one of the most cost effective interventions a business can make.
• Permission to slow down without losing edge. The myth that high performance requires constant urgency is finally being challenged. Regulated teams are not slower. They’re clearer. They make better decisions. They stay.

A small example, because this is where it gets real

I worked with a team recently where the leader told me, very honestly, “I think half my team is about to quit and I don’t know why.”

We didn’t start with a strategy session or a personality test. We started with breath. Then with naming what was happening in the body. Then with a few small practices the team could weave into their normal week.

Three months in, two of the people who were “about to leave” stayed. One said she’d genuinely forgotten what calm felt like and didn’t realise that was the thing she’d been chasing. The leader said his meetings were ten minutes shorter and twice as productive.

No grand restructure. No new perks. Just a workforce that started learning how to come back to ease, balance, and connection, on purpose.

The invitation for leaders right now

If your retention numbers are wobbling, if your engagement scores keep dipping, if your best people seem a bit checked out, it’s worth asking a different question.

Not “what perks can we offer?” but “what state are our people actually in?”

Because you can’t think your way out of a $2.9 trillion problem. You have to work with the body, with the system, with the very human reality that we are not machines that need optimising. We are nervous systems that need looking after.

The companies that figure this out first are going to be the ones their best people choose to stay with.
