Every leader I know can talk for an hour about the decisions they're proud of. The hire they took a chance on. The tough call they made under pressure. The pivot that saved the year. Ask them about the decisions they've been avoiding, though, and the room gets a lot quieter.

I recently sat down with Hyla Pollak on the Unmuted Podcast to talk about something I've seen play out at nearly every organization I've worked with, something she calls "people debt". It's the leadership version of technical debt: the short-term compromise you make today that quietly gets more expensive tomorrow. Except instead of a codebase, it's a person. A dynamic. A decision everyone in the room already knows needs to be made.

‍The reality is that culture isn't shaped most by what leaders say they value. It's shaped by what they let slide. You can have the most polished values deck in the building, but if everyone can point to the manager who's been "working on it" for eight months, that deck isn't what's actually training your team on what gets rewarded and what gets tolerated.

‍What People Debt Actually Is

People debt accumulates in a handful of familiar places. An underperformer who's been "coached" for two performance cycles running. A team dynamic everyone tiptoes around instead of naming out loud. Someone in a critical seat who was the right call eighteen months ago and clearly isn't anymore. Behaviour that contradicts what the company says it stands for, quietly excused because the person is otherwise talented, tenured, or just difficult to replace.

None of these show up on a balance sheet. But like any debt, they don't sit still. They accrue.

‍Why Capable Leaders Postpone the Call

This isn't usually about weak leaders. It's about smart, well-intentioned ones talking themselves into waiting one more quarter. Research from Robert Half found that managers spend, on average, over a quarter of their working hours coaching underperforming employees, time that's rarely tracked as a cost anywhere (Robert Half via NJBIA). And it's not always irrational. Research from Harvard Business School by Henrique Castro-Pires frames avoidance as a real cost-benefit calculation: confronting someone carries its own risk, from a defensive reaction to a formal complaint, so overlooking a minor issue can be the pragmatic call (reported by Quartz).

The trap is treating every hard people decision like a minor issue. Pick your battles is good advice. Picking every battle as "not this one" is how you end up with debt.

‍The Signal, Not Just the Cost

Here's the part that gets missed. The financial cost of a bad hire or a tolerated behaviour problem is real and worth naming. But the more expensive cost is what the rest of the team quietly concludes.

Culture Partners' research on underperformance found that when management lets poor performance slide, it demotivates the very employees you can least afford to lose. High performers pick up the slack, resent doing it, and start looking elsewhere (Culture Partners). What leaders don't address becomes just as powerful a signal about culture as what they actively promote. Every day that behaviour stays unaddressed and the “black cloud” gets bigger, the team is watching and learning exactly how far the stated values bend under pressure.

‍How the Debt Compounds

Debt that isn't paid down doesn't stay the same size. Gallup's most recent State of the Global Workplace report puts a global number on disengagement: $8.9 trillion in lost productivity a year, roughly 9% of global GDP (Gallup). That's not one bad apple. That's what happens at scale when tolerance for underperformance and misalignment becomes normal.

Then there's the timing trap. The longer a decision waits, the harder it becomes to make cleanly. Six months in, it's a coaching conversation. Eighteen months in, it looks sudden, unfair, or political, even though it's the same decision that's been overdue the whole time.

‍Paying It Down Without Overcorrecting

The answer isn't to swing the other way and start making snap calls on every performance blip or personality clash. That's its own kind of damage. What Hyla and I landed on is closer to a set of honest questions leaders can ask themselves before deciding to wait another quarter:

• Is this a pattern, or genuinely a one-off?
• Does it touch a core value, or is it a minor style difference?
• What did waiting one more quarter actually cost the team last time?
• If I made this call today instead of in six months, what would actually be harder about it?

Most leaders already know the answer. The debt isn't a knowledge gap. It's a getting-around-to-it gap.

‍A Final Thought

Leadership gets measured by the decisions people can see: the launch, the hire, the reorg. But every leader is also carrying a second ledger, made up of the decisions they know they need to make and haven't. That ledger doesn't stay hidden forever.

Your team already knows what you're avoiding. The only real question is how long you're willing to let them keep learning from it.
