Why Your Best Salesperson Just Handed in Their Notice

I had a call the other week that honestly didn’t surprise me at all, but the client was completely blindsided.

They said, “We don’t understand it, they were our best performer… why would they leave?”

And I just sat there thinking… you do understand it, you just haven’t joined the dots yet.

Because people don’t just leave out of nowhere. That’s the bit businesses get wrong every single time. They treat it like a sudden event, when actually it’s been building for weeks, sometimes months.

What usually happens is something small shifts first. Maybe the commission plan changes a bit. Maybe targets creep up. Maybe a decision gets made that doesn’t quite sit right. Nothing dramatic, nothing worth kicking off about… just enough to plant a seed.

Then something else happens. And then something else. And before you know it, that person who used to be all in is now doing the job, but they’re not in it anymore.

By the time they hand their notice in, they’ve already checked out. You’re just late noticing.

And here’s the bit that stings a bit. It’s very rarely about money on its own. Everyone jumps to that because it’s easy to blame. “They got offered more somewhere else.” Maybe they did. But good salespeople don’t leave a place they’re happy in just for a bit more cash. They leave when trust starts slipping.

That’s the real issue. Trust.

If someone joins your business on one set of expectations and six months later it looks completely different, they clock it. If targets keep moving, if commission quietly changes, if leadership decisions feel disconnected from what’s actually happening on the floor, they notice all of it.

And the good ones don’t sit around hoping it improves. They leave.

I see the same patterns over and over. Targets going up without a proper explanation. Top performers carrying weaker ones while nothing gets addressed. Decisions being made in a room by people who haven’t picked up the phone in years.

Then everyone’s shocked when the best person walks out the door.

In the UK, sales roles already have high turnover. That’s not because there aren’t good people. It’s because good people won’t tolerate environments that make their job harder than it needs to be.

So if you’re losing your best people, it’s worth asking a better question than “why did they leave?”

What changed?

Because something always did.

And if you don’t figure that out, you’ll replace them, feel relieved for a bit… and then be right back here again in six months having the same conversation.
