If you started a new job in the past few weeks, there's a date sitting quietly in your calendar that your HR induction pack almost certainly didn't flag. It isn't your birthday, your first appraisal, or even the end of your notice period from your old employer. It's the day you personally clock six months of continuous service — and from 1 January 2027, that date decides whether you can bring an unfair dismissal claim at all.
The Employment Rights Act 2025 received Royal Assent on 18 December 2025, and most of the coverage at the time focused on a headline that never actually happened. Labour's original manifesto commitment was to make protection from unfair dismissal a "day one" right, scrapping the two-year qualifying period altogether from an employee's very first day on the job. That proposal didn't survive contact with the House of Lords, where peers forced a series of last-minute concessions that reshaped the Bill in its final weeks. After a string of defeats late in the Bill's passage through Parliament, the Government dropped day-one rights and settled on something narrower but still significant. The qualifying period drops from two years to six months, with the change taking effect on 1 January 2027 rather than immediately at Royal Assent. Employment lawyers had spent over a year briefing clients on a day-one world that, in the end, ministers walked back under pressure from business groups and a sceptical upper chamber.
What Actually Changed, and What Got Quietly Dropped
Two years has been the standard qualifying period for ordinary unfair dismissal since 2012, when the Coalition government extended it from one year specifically to make it easier for employers to let new hires go without a tribunal risk. The Employment Rights Act 2025 cuts that window to six months — a reduction of eighteen months, not a rounding error. For an employee, this means the vulnerable stretch where you can be dismissed for almost any reason, with almost no recourse, shrinks from two Christmases to half a year.
Less widely reported is what the Government abandoned along the way. Early drafts of the Bill floated a statutory "initial period of employment" — reportedly nine months — during which employers could use a lighter-touch dismissal process for capability or conduct issues, with a shorter meeting-and-right-to-be-accompanied procedure instead of the full statutory disciplinary route. Employer groups largely welcomed it; unions were lukewarm. In the end, none of it made the final Act. There is no separate statutory probation framework, no light-touch procedure, and no nine-month anything. What you get instead is a single number — six months — with the ordinary fairness test applying in full from that point onward.
The Cut-off Date Almost Nobody Mentions
Six months.
Buried in the Government's implementation guidance is a transitional rule that matters more than most people realise, especially given today's date. Anyone employed on or before 1 July 2026 gets the new six-month protection automatically from 1 January 2027, regardless of how long they've actually worked there by that point — even someone who started on 30 June 2026 crosses the line the moment the clock strikes January. Anyone hired after 1 July 2026, by contrast, has to personally reach six months of service before the protection applies to them individually. If you started your current job in the second half of July 2026, you're in the second group, and your own six-month mark — not the January 2027 date — is the one that counts. Do the arithmetic on your own start date rather than assuming the same rule applies to everyone in the office.
Why the Compensation Cap Change Matters as Much as the Timeline
The Act also removes the statutory cap on the compensatory award for unfair dismissal, which currently sits at whichever is lower of 52 weeks' gross pay or roughly £118,223. Ministers haven't confirmed the exact date this abolition takes effect, though most employment lawyers expect it to land alongside the qualifying-period change rather than separately — nobody has explained why it would make sense to phase them apart. Removing the cap doesn't change whether you can bring a claim; it changes what a successful one is worth. For anyone on a salary well above the current cap threshold, that's not a footnote. It's the difference between a settlement that barely covers a few months of job hunting and one that reflects genuine lost earnings.
One thing worth saying plainly: don't assume this reform reaches you automatically just because you work in Great Britain. Employment law is devolved in Northern Ireland, and historically it has adopted Westminster reforms months or years later, sometimes with amendments, occasionally not at all. If you're working in Belfast rather than Bristol, check the Northern Ireland Assembly's own timetable before you plan around any of these dates — the six-month rule described here is a Great Britain change, not a UK-wide one by default.
What This Means If You're Interviewing Right Now
Candidates have started asking recruiters about probation length as though it's the main variable that matters, and that's the wrong question to be asking in 2026. A contractual probation period of nine or twelve months no longer buys an employer meaningfully more legal room than a three-month one, because the statutory qualifying period overrides it either way once you hit six months of actual service. Ask instead about notice periods, about how performance concerns get raised in practice, and about whether the company has a track record of extending probation rather than making early decisions. Those questions tell you far more about how you'd actually be treated than the number printed in the offer letter.
If a recruiter or hiring manager tells you the reform "doesn't really change anything" for your situation, don't take that at face value — push them on specifics, because in most cases it changes quite a lot. A shorter qualifying period tends to make employers more decisive earlier, not less, since they know the low-risk window is closing faster than it used to. That can cut both ways: some managers will invest more in early feedback and onboarding to make a fair decision quickly; others will simply let people go at the four or five-month mark rather than risk crossing into the protected period with any doubt still on the table. Ask which kind of manager you'd be working for before you sign anything, and don't assume good intentions just because the company's careers page talks about culture and development.
What This Means If You Started a Job Recently
If you're between four and six months into a new role right now, this is a reasonable moment to ask for a structured check-in rather than waiting for whatever review cycle the company defaults to. Not a vague "how am I doing" chat over coffee — a specific conversation with clear, written feedback on where you stand, ideally with next steps attached. Employers who are quietly building a paper trail toward a dismissal decision tend to go quiet rather than vague, so a sudden absence of feedback after months of normal management contact is itself a signal worth noticing.
Keep your own record of anything relevant, starting now rather than after a difficult conversation has already happened:
- Emails or Slack messages praising specific pieces of work
- Positive feedback from clients or colleagues, even informal messages count
- Any written objectives you were given, and a note of whether you actually hit them
- Dates and short summaries of one-to-ones, especially if the tone shifts noticeably from one meeting to the next
None of this guarantees anything if you haven't yet reached six months of service and the reform hasn't taken effect for you — that's the reality of where the qualifying period still sits today, in July 2026, ahead of the January 2027 change. But it puts you in a far stronger position the moment your own protection does kick in.
The Number That Actually Matters
Ignore the headlines about day-one rights that never made it into law, and ignore the nine-month probation proposal that got dropped somewhere in a Lords committee room. The number to write down is six months, the date to check is 1 July 2026 against your own start date, and the year to watch is 2027. Everything else in this reform is detail dressed up as news.
