Hiring a school leaver in August feels like pure optimism: a bright new starter, a handshake, a start date, and you get back to your week. But there’s a timing detail in UK employment law that can catch employers out, and it starts much earlier than most people think. From 1 January 2027, the qualifying period for ordinary unfair dismissal drops to six months. That means anyone you hire from 1 July 2026 could qualify the moment the law takes effect, even though nothing “changed” on 1 July itself.
We keep this practical and calm: what the date really means, what else arrives in January (including the removal of the compensation cap and fire and rehire becoming automatically unfair), and why “protected” doesn’t mean “untouchable”. If someone is not right for the job, you can still act, but you need fair reason, fair process, and good notes. The law isn’t here to punish good employers, it’s here to make sloppy decisions expensive.
Then we get into the real pressure point: probation. If you run a standard six-month probation, your decision point can collide with the exact moment protection kicks in, leaving you no breathing space if reviews slip. We talk through how to set probation under six months, diarise review dates from day one, and complete a suitability assessment before the threshold. We also cover the day-one essentials that protect you and your new starter straight away: a written contract, right to work checks, and policies and payroll that reflect day-one rights like statutory sick pay, paternity leave, and unpaid parental leave.
