I have hired people I was too scared to let go. Not because they were doing great work, but because letting them go meant admitting I got the hire wrong and re-opening a role I’d already told everyone was closed. So I sat on it. The probation period ran out, the offer became permanent by default, and a decision I should have made in month two I quietly refused to make at all.

That instinct is common, and it costs more than one wrong salary. It quietly makes your team less diverse. The chain from “I can’t face a hard conversation” to “everyone here looks a bit like me” is shorter than it sounds.

When you can’t reverse it, you over-index on safe

If you don’t trust yourself to end a hire that isn’t working, then every hire feels permanent from the moment you sign. And permanent decisions make you cautious in a specific direction. You stop asking “could this person be great?” and start asking “what’s the chance this blows up?”

The candidate who minimises that chance is the one you can read instantly. Same stack, same kind of company, same shape of career, talks about the work the way you do. Nothing lights up your threat model because nothing is unfamiliar. So you hire the reassuring pattern-match, tell yourself it was rigour, and move on.

Do that ten times and you don’t get a team. You get a mirror.

The mirror, in my case, is a middle-aged white bloke

I’ll say the awkward part plainly, because dressing it up helps nobody. When I hire on gut, on “this person feels safe”, the person who feels safest to me tends to look and sound a lot like me: another white, middle-aged man who took roughly the path I took. Not because I set out to build that team, but because “safe” and “familiar” collapse into the same thing under pressure, and what’s familiar to me is, well, me.

This isn’t diversity in the box-ticking sense. I’m not talking about a spreadsheet with demographic quotas on it. I mean the thing that actually makes teams good: a spread of backgrounds, of instincts, of ways to attack a problem. The engineer who learned to code at forty after a decade doing something else. The one who came up through a bootcamp instead of a comp-sci degree and reaches for different tools because of it. The person whose lived experience means they catch the failure mode you’d have shipped straight past. You don’t get any of that by hiring your own reflection with a different name.

And you especially don’t get it when every seat feels like a bet you can never unwind. Homogeneity isn’t usually a decision. It’s the residue of a hundred small choices to play it safe.

Probation is the thing that lowers the stakes

Here’s the move. A probation period, used as designed, is a real two-way trial. Both sides are checking their assumptions with an actual exit on the table, not a formality you sleepwalk through on your way to making the offer permanent.

In Australia that structure is baked into the law, which helps. Under the Fair Work Act, an employee generally can’t bring an unfair dismissal claim until they’ve completed a minimum employment period: at least 6 months, or 12 months if you’re a small business with fewer than 15 employees. That’s no licence to be careless, and you still owe anyone a fair go and honest feedback. But it does mean the early window is a trial by design, and treating it as one is the intended use, not a loophole.

When you actually trust that window, the maths on any single hire changes. The downside of a wrong call drops from “I’m stuck with this for years” to “we’ll know inside a few months, and part ways honestly if we need to.” Lower stakes on the bet means you can afford to take a less obvious one.

That’s what widens the funnel. You can back the career-changer, the bootcamp grad, the person whose CV doesn’t map cleanly onto your team’s, because their potential is real even when the pattern-match isn’t there. Probation de-risks the individual bet, and that’s exactly what lets you stop hiring for reassurance and start hiring for upside.

What this asks of you

The catch is that none of it works if you won’t use the period. A probation you’re too soft to act on is just a permanent hire with a trial-shaped label, and you’re back to needing every hire to be perfect.

So the discipline is the unglamorous bit. Set real expectations in week one. Give honest feedback early, not a fortnight before the deadline when it’s too late to change anything. Have the check-ins you’d rather avoid. And if it isn’t working, make the call while it’s still a call, kindly and clearly, instead of letting the calendar decide for you.

Do that, and a strange thing happens. Because you know you can act, you stop needing to be certain up front. Because you don’t need certainty, you stop defaulting to the safe, familiar hire. And the team you end up with is broader, sharper, and less like a room full of people who took the same road you did.

Using probation properly is good performance management, and it’s also one of the most honest levers you’ve got for building a team that doesn’t just reflect you back. If your hiring keeps producing the same person over and over, let’s talk about why.
