On this epsiode, burnout expert Cait Donovan explains why burnout isn’t about overwork. It’s a pile-up of mismatches. Learn the signs, the brain science and what leaders can do.
I came across a stat recently that stopped me: 83% of workers reported some level of burnout going into 2026. That’s this year. Most of us blame long hours or chronic stress, and for years so did I. I overwork (you all know that), and whenever I felt exhausted, I assumed I was failing.
Then my friend Cait Donovan told me, “It’s actually not that. It’s a mismatch problem.” I told her, “Girl, I need to have you on the podcast.”
Cait hosts FRIED, a top 1% podcast with over a million downloads, and she wrote the new book Mismatch: Why Good People Burn Out in Good Organizations.
In this epsiode we're diving into why burnout isn’t a personal failure and isn’t simply an overwork problem.
We talk about how to tell normal tiredness from real burnout, what a 2025 brain-imaging study found in burnt-out brains, and how childhood patterns like perfectionism and people-pleasing set us up for burnout. We also cover the one emotion that signals a mismatch every time. As a clinical exercise physiologist, I added what chronic fight-or-flight does to our long-term health, and I asked Cait the question I keep hearing from the executives I work with: what should leaders actually be looking for?
I took notes while editing this one, and I think you’ll want to as well.
In this episode, you’ll learn:
1. How can I tell if I’m burnt out or just having a bad week?
Look at whether rest still works. Feeling tired by Friday and refreshed by Monday is normal. Cait explains that burnout is when your recovery no longer works: a weekend, a vacation or even a sabbatical doesn’t restore your energy.
2. If burnout isn’t caused by overwork, what causes it?
According to Cait, burnout comes from a series of mismatches that compound over time. They show up across six areas of life: workplace, family, culture, environment, health, and personal traits and coping habits. No single mismatch causes burnout. They pile up slowly until something breaks.
3. Why do so many high achievers miss the signs of burnout?
Patterns like perfectionism, people-pleasing and hyper-independence often develop in childhood. They can weaken interoception, which is your ability to notice what’s happening inside your body. As Cait puts it, “Your brain wasn’t designed to notice.” Recovery starts with the basics: pee when you need to pee, rest when you’re tired and eat when you’re hungry.
4. What is the biggest warning sign of burnout at work?
Resentment. Cait says it signals a mismatch every time, whether the cause is structural, relational or personal. Leaders can spot it on their teams through passive-aggressive comments, growing negativity and short “as per my last email” replies.
5. Can burnout be prevented, and what should I aim for instead?
Cait doesn’t fully believe in burnout prevention. The people who need it most often can’t feel the warning signs, so they assume the advice is for someone else. She recommends aiming for a “75% match” instead of a perfect life: fix the mismatches you can, so you have enough energy to handle the ones you can’t.
