How to avoid costly probation mistakes
Let me paint you a picture.
You’ve spent weeks recruiting. You’ve interviewed, made an offer, done all the admin. Your new hire starts and… within a few months, something’s not working. They’re struggling. Mistakes are piling up. You’re wondering if you made the wrong call.
So you end their employment. Probation failed. Job done, right?
Not necessarily.
Because here’s the thing most business owners don’t realise until it’s too late: the problem usually isn’t the employee. It’s the process that surrounded them from day one.
And with significant Employment Rights Act changes on the horizon – changes that will reduce the time before employees can bring an unfair dismissal claim from two years down to just six months – getting your probation process right has never been more important.
The real cost of a failed probation
Beyond the obvious cost of recruiting again, a badly managed probation period can expose you to legal risk. If you haven’t followed a fair process, documented concerns properly, or given the employee the support they needed to succeed, you could be looking at an unfair dismissal claim.
Employment tribunal legal fees start at £20,000. Compensation is on top. And in discrimination cases, there’s no cap at all!
Prevention is always cheaper than crisis management. Which brings me to the stories I find myself telling again and again.
Jane: the employee set up to fail
Jane started in a sales office, tasked with typing up menus for events. Straightforward enough on paper.
What her manager didn’t know was that Jane was dyslexic.
On her very first day, she overheard colleagues mocking another dyslexic employee. That was enough. She never felt safe enough to speak up about her own struggles, never asked for help, and quietly battled on while mistakes mounted up.
Her manager didn’t ask what was going wrong. Jane failed her probation.
Later, she told HR that just two simple adjustments would have changed everything: recording training sessions on a dictaphone and typing up her notes at home.
That’s it. Two things. Nobody thought to ask.
The business lost a potentially great employee. And depending on how the process was handled, they may also have exposed themselves to a disability discrimination claim. Discrimination claims are uncapped. That’s not a risk worth taking.
Alan: the new hire who walked out in a week
Alan’s first day was spent battling IT just to get a login. No structured training. No induction. No one showing him the ropes.
Someone told him: “You’ve done this before, so you can just get on with it.”
He quit within a week.
All that recruitment time, all that effort to get him through the door, gone. Because no one thought to make him feel supported, welcomed, or set up to succeed.
This is more common than you’d think. And it’s entirely preventable.
So what does a good probation process actually look like?
It’s not complicated, but it does require intention. Here’s what I recommend to every client:
1. A proper induction – not just a handbook and a login.
Think structured, planned, and human. Someone should be responsible for making that new hire feel like they belong.
2. Regular check-ins throughout – not just at the end.
If someone is struggling, you want to know about it at week two, not week eleven. Regular one-to-ones give you the chance to spot problems early and address them properly.

3. Ask what people need to do their best work.
Not just “do you need any reasonable adjustments?” – that question shuts people down. Try: “what do you need to work well?” You’ll get very different, very useful answers.
4. Train your managers to actually manage.
Your probation process is only as good as the people running it. If your line managers don’t know how to have difficult conversations, spot early warning signs, or give constructive feedback – the process falls apart. This is where training pays for itself, many times over.
5. Document everything.
If you do need to end employment, you need a clear paper trail. Notes from one-to-ones, records of concerns raised, evidence of support offered. Without this, you’re exposed.
Why this matters even more right now
The Employment Rights Act is coming, and one of the most significant changes is to unfair dismissal rights. Under the new legislation, employees will be able to bring an unfair dismissal claim after just six months which for most businesses aligns with the end of probation.
That means your probation process is about to become your first line of legal defence.
If it’s a bit woolly right now, think no proper structure, no regular check-ins, no documentation, you need to sort that before the changes land.
The businesses that get ahead of this will be far better placed than those who wait until something goes wrong.
Prevention beats panic every time!
Most probation failures aren’t down to hiring the wrong person. They’re down to not giving the right person the right start.
Jane could have thrived with a dictaphone and a bit of curiosity from her manager. Alan could have stayed if someone had taken an hour on day one to properly show him the ropes.
Small changes. Big difference.
