Probation is not a safety net. It is a process.
If you do not manage probation properly, it offers far less protection than many employers realise. A probation period is not a free pass to let someone go without care. It is a window to make a fair, well-evidenced decision about whether someone is right for the business, and to give them a real chance to get there.
Handled passively, it protects you far less than you think. Handled actively, it is one of the most useful tools you have.
Treat probation as an active process from day one, not a box that quietly ticks itself at the end.
Why now matters: the planned unfair dismissal reform
The law does not change on 1 July 2026, but it is an important date for employers. Anyone recruited from this summer is expected to have six months' service by 1 January 2027, when the Government currently intends to reduce the qualifying period for ordinary unfair dismissal from two years to six months.
In simple terms, employers will have less time to decide whether someone is the right fit before fuller protections apply. That makes a sharp, well-run probation process more important, not less.
If you are recruiting this summer, review your probation process now, rather than waiting for the reforms to land.
The pattern I see again and again
I hear the same thing time and time again: “I knew after a few weeks they weren't quite right, but I hoped things would improve.”
Before the owner knows it, probation is nearly over, no difficult conversations have taken place, and they are left wondering what to do next. The chance to address it fairly and early has quietly slipped away.
Don't wait, and don't hope it improves on its own. Have the conversation early, while you still have options.
What good probation looks like
Set clear expectations from the first day, so the person knows exactly what good looks like. Meet regularly throughout the period, not just at the end. Tell people when they are doing well, and tell them honestly when they are not.
Most people genuinely want to do a good job. Giving honest feedback early gives them the chance to improve. And if they do not improve, you will know you have done everything you reasonably could before making a decision.
Set expectations on day one and review regularly. Never save the honest feedback for the last week of probation.
The real cost of getting it wrong
Getting probation wrong is expensive: the cost of recruiting, training and lost productivity, managers spending hours on problems instead of running the business, other employees carrying extra work, customers receiving a poorer service, and then recruiting all over again.
If the process has not been handled fairly or properly documented, you could also find yourself dealing with ACAS Early Conciliation or an Employment Tribunal. But in my experience, the biggest cost is rarely the legal one. It is the stress, the sleepless nights, and the uncertainty of wondering whether you are making the right decision.
Good probation is not about making it easier to dismiss people. It is about better recruitment decisions and catching problems before they grow.
Three questions to ask if you are recruiting this summer
Does every new employee know exactly what is expected of them?
Are your managers having regular conversations throughout probation, instead of waiting until the end?
If someone was not the right fit, could you honestly say you had managed the process fairly?
If the answer to any of those is no, that is where to start, before your next hire begins.
The bottom line
Employment law will keep changing. What will not change is this: businesses that deal with people problems early, communicate honestly, and do not avoid difficult conversations are almost always in the strongest position. The earlier you deal with a problem, the more options you have.

Key takeaways
- Probation is a process, not a safety net. Managed passively, it protects you far less than you think.
- Planned reforms are set to cut the unfair dismissal qualifying period from two years to six months, so probation matters more.
- Set expectations on day one, meet regularly, and give honest feedback early, not in the last week.
- The biggest cost of getting it wrong is usually the stress, not the legal bill.
- Deal with it early. The earlier you act, the more options you have.
