How to safeguard your business from costly probation mistakes
I was talking to a client recently who has one of the best recruitment processes I’ve seen. He hires for values and behaviours, not just what’s on someone’s CV. Genuinely impressive stuff.
And then it all falls apart at probation.
Because for all that structure on the way in, what happens at the end of probation is often just a chat. Informal, undocumented, decided on gut feel. That’s a problem on a good day. From January, it’s about to get a lot more expensive.
Recruitment was never the whole answer
Good hiring reduces your risk. It doesn’t remove it. You can ask every values-based and competency-based interview question in the book and still end up with a mismatch, a bad month, or someone who simply isn’t right for the role. That’s what a probationary period is for.
The recipe for success was never just recruitment. It’s recruitment and a great probationary period, working together. Skip the second half, and the first half only gets you so far.
Why this matters more from January
If you took someone on from 1 July 2026 onwards, they now qualify for unfair dismissal protection at six months, not two years. The first wave of those six-month marks lands this January. In addition, anyone you took on before 1 July will also qualify if they have over 6 months service by 1 January 2027.
That’s a significant cut to the amount of time you have to get a hire right, and a significant increase in the number of people who could bring a claim if you get it wrong.
The numbers behind that aren’t small. Defending a tribunal claim typically costs somewhere between £10,000 and £25,000 in legal fees, climbing past £20,000 for discrimination or whistleblowing claims – and that’s before you get anywhere near a payout. Average tribunal awards then sit between £4,300 and £8,500 on top. Note, that’s just the average amount!
Compare that to what a properly run probation period actually costs: a bit of structure, some documentation, and a manager who knows what they’re doing. Framed like that, spending a few hundred quid a month on getting it right isn’t really a decision.
What a good probation process actually looks like
Good probation starts on day one, not in week eleven. That means telling someone plainly what they’re being assessed on, and what you expect to see by the end of their probation. Link it to the standards you’ve already set out – if your team doesn’t know what “good” looks like, you can’t fairly judge whether they’ve hit it.
From there, it needs regular check-ins, not just a single conversation at the end. A simple midway review, where a manager records whether someone’s on track or needs to improve before the end of probation, does most of the heavy lifting here.
Let people see the bus coming
This is one of the ideas at the heart of how I work with clients: people should see the bus coming.
What usually happens is the opposite. Managers wait, and wait, and wait, then fail someone’s probation, and nobody saw it coming – least of all the person who’s just lost their job. That’s rarely a performance failure. It’s a process and documentation failure, and most importantly, a management failure.
If you’ve told someone what’s expected of them, recorded where they’ve fallen short, agreed a plan, and given them a fair chance to hit it, the final conversation isn’t difficult. It’s just the next logical step in a conversation you’ve already been having.
Give your managers the toolkit, not just the responsibility
None of this works if you hand a manager the responsibility for probation without giving them the tools to manage it. A manager who’s never been shown how to run a proper check-in will default to what’s comfortable: an informal chat when things are clearly fine, or awkward silence when they’re not.
A toolkit fixes that. A midway form that prompts a plain yes or no on progress. A clear link back to the expectations set on day one. A structure that means nothing rests solely on a manager’s memory of a conversation that happened three months ago.
Prevention beats panic, every time
A brilliant recruitment process will get good people through your door. What keeps them, and what protects you if it doesn’t work out, is what happens next.
Build a probation process with real structure, give your managers the toolkit to run it properly, and you get two things at once: fewer tribunal risks, and fewer conversations that feel like ambushes to the person on the other side of them.
If your probation process currently amounts to “we’ll figure it out at the end,” now’s the time to fix that – well before January.
