Probation Periods Just Got a Lot More Important - Here's How to Get Them Right

With day-one unfair dismissal rights arriving in October, a well-structured probationary period is now your most important risk management tool. Here's how to build one that works.

Until now, many employers have treated probationary periods as little more than a formality - a box to tick before confirming someone's employment. From October 2026, that approach carries real legal risk. With employees able to bring unfair dismissal claims from day one, the probationary period becomes your primary mechanism for managing performance risk in the early months of employment.

A legally robust probationary period starts before the employee's first day. Their contract should clearly set out the length of the probation, the standards expected, and the process that will be followed if those standards aren't met. Ambiguity at this stage creates problems later - if an employee doesn't know what's expected of them, it's very difficult to justify a dismissal on capability grounds.

During the probationary period, regular structured check-ins are essential. These don't need to be lengthy or formal, but they should be documented. A brief written record of what was discussed, any concerns raised, and any support offered creates the evidence trail you need if you later need to take action. Without documentation, your position in any Tribunal claim is significantly weakened.

If performance or conduct concerns arise during probation, address them promptly and directly. The instinct to wait and see - hoping things will improve on their own - is understandable, but it works against you. Early, honest feedback gives the employee the opportunity to improve, and demonstrates that you acted fairly. If improvement doesn't follow, you have a clear record of the concerns raised and the support provided.

The formal probationary review at the end of the period should never be a surprise. If you've been having regular conversations throughout, the employee should know where they stand. The review is an opportunity to either confirm employment with confidence, extend the probation with clear targets, or - where necessary - end the employment with a documented, fair process behind you.

Getting probationary periods right is one of the highest-value investments you can make in your HR processes right now. If your current approach is informal or inconsistent, October is the deadline you need. A Salus HR consultant can help you design a probationary framework that protects your business and sets your new starters up for success.
