Decision Debt Is Quietly Costing You Your Best People

I regularly meet HR Directors who can explain, in detail, why a leader is experiencing symptoms of burnout. What they struggle to explain is why the strongest person on that leader's team handed in their notice six months before anyone saw it coming. Those two things are usually connected, and few organisations are looking at the link.

Decision Debt is what happens when a leader keeps making calls while cognitively depleted, without the recovery to clear it. I've written about the mechanism before. What I haven't written about is where it shows up first, and it isn't in the leader's own performance review. It shows up in who leaves.

What decision debt does to a leader's calls

A leader carrying decision debt keeps making decisions, but the shape of those decisions changes without anyone naming why. Unclear situations sit unresolved for longer than they should, ownership gets delayed rather than handed over, and the safe option gets chosen over the better one, not because the leader lacks judgement, but because judgement under depletion defaults to whatever protects against further depletion. That isn't a failure of character so much as what happens to judgement once the system behind it has run past capacity.

To the leader this feels like caution, but the people around them read it as something else entirely.

Why your best people notice first

The people who leave first are not always the people who appear to be struggling. Often it's the person who joined wanting real responsibility and the room to prove themselves, watching a leader start sitting on decisions, withholding ownership, or defaulting to the safest version of every call. That person rarely reads it as their manager being tired. Instead, it reads like a ceiling has appeared over their head, and ambitious people don't usually wait around under one.

SHRM's January 2026 CHRO research found that leadership and manager development has been the top priority for CHROs two years running, and that over half of employees who see their organisation as ineffective at meeting workplace needs are at least somewhat likely to leave within the year. LHH's March 2026 View from the C-Suite research put retaining top talent as the single biggest internal talent priority, right alongside ineffective decision-making, which has also held for a second consecutive year. Those two things are sitting in the same reports, on the same pages, and few organisations are drawing a line between them.

The nuance that matters here

I want to be careful with this, because it would be easy to overstate it. Decision debt is not the reason your best people leave. Pay, career progression, workload and job security still carry the most weight in most people's decision to stay, and any speaker telling you otherwise is simplifying something that isn't simple. What the evidence supports is narrower and, I think, more useful. Decision debt is an overlooked contributor. It's the thing sitting underneath a retention problem that gets diagnosed as culture, or engagement, or compensation, when the actual driver is a leader who has run out of the cognitive capacity to make decisions look like trust.

And so the fix isn't a wellbeing initiative bolted onto an already full calendar, it's protecting the leader's capacity to make clear, timely calls before the depletion changes the shape of every decision underneath them. That's the part of the RESET Framework most organisations skip, because it looks like a performance problem rather than a resilience one, right up until the exit interview.

Before the next round of exit interviews gets written up as a culture or comp issue, it's worth asking a different question: are the leaders your best people are leaving also the leaders who've been carrying the heaviest, longest run of undivided decisions, without anyone checking whether they still have the capacity to make them well?

That's usually where I start with a leadership team, not with resilience training, but with decision quality and what protects it when the pressure doesn't let up.
