How do I know if I'm too slow to fire an underperforming employee?

Most Australian small business owners already know who on their team needs to go long before they do anything about it. The decision has been on their mind for weeks, sometimes months, while the excuses pile up and the performance never actually improves. By the time the call finally gets made, what should have been a straightforward exit has usually turned into a far harder legal process, and the rest of the team has already worked out exactly what you're prepared to tolerate. Here is why business owners drag their feet on firing decisions, what the delay is actually costing the business in the meantime, and the legal groundwork worth checking before you make the call.

What actually happens when you sit on a firing decision too long?

The longer a firing decision stays unmade, the more it costs you on every front. Waiting past the probationary period without documented warnings makes an exit far harder to execute cleanly, and it does nothing to protect the business from an unfair dismissal claim regardless of how justified the decision actually is. Inside the team, watching poor performance go unaddressed erodes trust in you as the leader faster than almost anything else you can do, and your best people are always the ones who notice first. None of this resolves itself while you wait. In fact, it only compounds.

If you're running a business with more than a few staff, there's a good chance you've had the experience where someone who wasn't working out was on your mind for weeks. You've rehearsed the conversation in the car, in the shower, at 2am when you can't sleep, and then talked yourself out of it every single time. Maybe you're telling yourself they'll turn it around, or that now isn't the right time, or that you just need to get through this quarter first.

Meanwhile you and the rest of the team are picking up the slack, wondering if you're overreacting, and resenting a problem that's entirely within your power to fix.

What to check before you make the call

Before anything else, look at where the person actually sits in their employment. If they're still within their probationary period, you're generally in a stronger legal position, because this usually aligns with the Fair Work minimum employment period, the window during which someone is not eligible to lodge an unfair dismissal claim. That protection is not absolute. Nothing stops a person from lodging a claim regardless of eligibility, but a well-worded probation clause in your employment contracts still gives you far more room to move than you'll have later.

Outside of probation, the real question is whether you've actually given the person a documented warning. Not just time spent quietly annoyed while nothing gets said, but a genuine conversation where you named the performance issue, explained exactly what's required, gave them a real opportunity to improve, and told them plainly what happens if they don't. It's also worth being honest with yourself about what you're actually dealing with. A performance issue, a conduct issue, and a personality clash all need to be handled differently, and confusing one for another is part of what makes these decisions feel so much harder than they need to be.

Why business owners delay a decision they've already made

Almost every business owner I work with wants to give the person the benefit of the doubt. If I just give them a bit more time, they'll turn it around. The trouble is, after two decades of doing this work, I can tell you with real confidence that people don't have a sudden epiphany about their own performance. If you haven't told them clearly there's a problem, they're not going to work it out on their own.

There's also a genuine weight of responsibility that most business owners feel for their employees' livelihood, and that instinct is not a bad one. But it tips into something else when it means tolerating performance that should have been addressed months ago. Layered on top of that is fear. Fear the person will argue back, fear of an unfair dismissal claim, fear they'll tell everyone what a terrible employer you are, and fear about how the rest of the team will read it. Will they think you can't run the business? Will they lose respect for you? Will they wonder if they're next? All of that is real, and none of it changes what the delay is quietly doing to the business while you sit with it.

What the delay is actually costing your team

Your best people are watching how you handle this, whether you realise it or not. When someone on the team is difficult to work with, doing low quality work, or simply not pulling their weight, and nothing happens, your highest performers notice the inaction before anyone else does. Nothing pushes an A player toward the door faster than watching the boss fail to act on a problem everyone can see.

It also tells everyone else what ‘acceptable’ looks like. If one person can be late every day or coast through their role without consequence, other team members start to wonder why they're holding themselves to a higher standard. And in the meantime, the rest of the team is almost certainly covering for the gap, making sure the client still gets serviced and the deadline still gets hit, often without you even seeing it happen. That covering builds resentment fast, particularly when it goes unrecognised, and it is rarely the underperformer who ends up walking out the door first because of it.

Where confidence in the decision actually comes from

Confidence does not come from thinking about the decision for longer. It comes from looking at the facts objectively and taking the legally appropriate action. Almost every business owner I've worked with tells me the same thing after they finally act: the team reveals exactly how much they'd been covering, how long they'd been waiting for this to happen, and how relieved they are that it finally has. That information was always there. You just could not see it until the decision was made.

Being slow to fire someone who is not performing is effectively paying a wage for work that is not getting done, is not supporting the team, and is not relieving any of your own workload. If you run a business with staff, a termination will come at some point. It is one of the parts of the job nobody warns you about, and the goal is not to avoid it forever, it is to not let the decision sit for months longer than it needs to once you already know what has to happen.

There's a real difference between the exit that happens on time and the one that happens under pressure.

A business owner I worked with recently had known for months that a team member's performance was not where it needed to be, but nothing had ever been raised with the employee directly. By the time she came to me, she wanted the person gone immediately. We couldn't do it legally, because nothing had been documented and no warning had ever been given, so we had to start the process properly: a formal conversation, a genuine improvement period, a real opportunity to change before any exit could happen. What could have been resolved in month three of the probationary period took close to two months once it was done correctly, purely because the first conversation never happened when it should have.

Compare that with a business owner who deals with the same situation during probation. The conversation is short, the process is simple, and if the person genuinely cannot meet the standard required, the exit is straightforward and well within the business's rights. Same underlying problem, completely different experience, and the only real difference is timing.

Does the probationary period fully protect me from an unfair dismissal claim?

No. It generally aligns with the Fair Work minimum employment period, which means someone is not eligible to lodge a claim, but nothing legally stops a person from lodging one regardless. A well-worded probation clause still puts you in a far stronger position than waiting until after that period has passed.

How many warnings do I legally need to give before I can terminate someone?

There is no fixed legal requirement for a specific number of warnings unless your own workplace policy states one. What matters is that the person has been given a genuine, documented opportunity to understand the issue and improve before any decision to terminate is made.

What's the difference between a performance issue and a personality clash?

A performance issue is about someone not meeting the standard of the role despite being given a fair opportunity to do so. A personality clash is about fit rather than capability, and it needs to be handled honestly as exactly that, rather than dressed up as a performance conversation it isn't.

Will firing someone make my team think they could be next?

Generally not, if the decision is clearly performance or conduct based and has been handled fairly. What actually damages trust is watching poor performance go unaddressed for months, not watching a leader make a fair and necessary call.

How do I know I'm not just being impatient rather than justified?

If you've already given a clear, documented warning and a genuine opportunity to improve, and nothing has changed, that is not impatience. That is a decision that has already been made and is simply waiting to be actioned.

If you know exactly who needs to go and you are still waiting to feel ready to make the call, that readiness is not coming, and every week you wait is a week the decision gets harder to make well. Getting the legal process right matters here, and it is exactly the kind of thing we work through together with clients inside PowerBoss.
