UK manufacturers and engineering firms are facing one of the most substantial regulatory overhauls in a generation. Consequently, human resources departments must rapidly redesign their recruitment and operational workflows to avoid a sharp increase in tribunal risks.
At Smart Manufacturing Week in Birmingham, industrial leaders gathered to dissect these imminent statutory changes. National manufacturers’ organisation Make UK has issued an urgent warning: while the core reforms under the Employment Rights Act 2025 formally take effect on 1 January 2027, their practical impact will hit businesses far sooner—affecting any new worker joining an organisation from 1 July 2026 onwards.
At the same time, a separate regulatory shift from the Equality and Human Rights Commission (EHRC) regarding single-sex service spaces is forcing companies to re-evaluate their physical site infrastructure. Together, these updates mean employers must swiftly rethink how they manage both their people and their premises.
The Sunset of the Two-Year Rule: Unfair Dismissal Overhauled
For more than a decade, UK companies operated with a comfortable statutory buffer. Workers generally required two years of continuous service before they could bring an ordinary unfair dismissal claim. Instead, from 1 January 2027, that qualifying window will shrink to just six months.
Importantly, this is not just a future problem. Because the six-month rule applies immediately on New Year’s Day 2027, anyone hired after 1 July 2026 will automatically cross that protective threshold the moment the clock strikes midnight.
Furthermore, the administrative burden is increasing. Employers must now provide formal written reasons for a dismissal after six months rather than two years. Crucially, the traditional safety net for corporate finance has been completely dismantled: the statutory cap on unfair dismissal compensatory awards (previously limited to £123,543 or a year’s actual pay) will be completely removed for any termination taking effect on or after the implementation date.
Re-Engineering the Probationary Period
With the financial risks of litigation escalating from the very start of the employment relationship, companies cannot afford to let underperformance drift. Rather than treating probation as a passive onboarding exercise, managers must use it as a rigorous diagnostic window.
Clearly, the standard six-month probationary contract template is no longer fit for purpose. If an underperforming employee reaches month six, they will instantly acquire full unfair dismissal protection.
Therefore, Make UK advises mid-market and enterprise businesses to transition to a strict four-month contractual probationary model for all new starters. This shorter timeframe gives managers long enough to assess a candidate’s suitability, while leaving a critical one-month buffer to extend the trial period if someone is off on sick leave, before the six-month statutory deadline hits.
When planning an exit, timing is everything. Because employees are entitled to a statutory one-week notice period, companies must finalize any probation dismissals at least one week before the six-month milestone to ensure the notice period does not push the employee over the legal threshold.
Watertight Documentation and Manager Upskilling
Because the Employment Rights Act also extends the time limit to file an employment tribunal claim from three to six months, cases may not reach a courtroom until years after an exit occurs. By that time, key supervisors or HR personnel may have left the business.
As a direct result, internal documentation must be flawless. Line managers need urgent, targeted training to ensure they are actively managing underperformance, clearly documenting expectations, and building robust, fair paper trails.
Infrastructure Dilemmas: The Gender and Facilities Conflict
While HR teams scramble to rewrite employment contracts, facilities managers are facing a separate, complex challenge regarding workplace toilets and changing rooms.
On 21 May 2026, the EHRC laid an updated statutory Code of Practice for services, public functions, and associations before Parliament. While this specific Code targets service providers rather than employers directly, its legal foundations signal a clear direction of travel for workplace rules.
Specifically, the Code reinforces the 2025 Supreme Court ruling (For Women Scotland Limited v The Scottish Ministers), confirming that the terms “woman”, “man”, and “sex” within the Equality Act 2010 refer strictly to biological sex. It notes that a Gender Recognition Certificate does not alter a person’s legal sex for separate or single-sex service spaces.
Navigating Inconsistent Case Law on the Factory Floor
Employers currently find themselves in a challenging legal position. Make UK has been actively urging the Government and the EHRC to publish standalone, explicit guidance for workplaces, but a revised Employment Code has not been updated since 2015.
For now, businesses must balance two competing legal requirements:
The Equality Act 2010: Protecting transgender staff from direct or indirect discrimination and workplace harassment.
Workplace Regulations 1992: Mandating the provision of “suitable and sufficient” toilets, which recent High Court rulings interpret as separate facilities for biological men and biological women.
Ultimately, ignoring the issue is a recipe for internal friction. To minimize legal vulnerabilities, forward-thinking operators are avoiding extreme measures. Instead, they are adopting a balanced approach: maintaining separate, single-sex facilities based on biological sex, while simultaneously installing self-contained, gender-neutral individual spaces open to all staff. This ensures that no employee is left without necessary facilities.
Change Management: The Double-Edged Policy Audit
To scale safely through these simultaneous legislative shifts, executives must view this period as a vital change-management checkpoint.
Clearly, the era of casual HR compliance is over. Companies must audit their entire operation, from the wording of their recruitment ads and the length of their probationary clauses to the layout of their factory floor changing rooms. Businesses that implement these structural protections today will preserve their workplace culture, protect their margins, and build a highly resilient operation ready for the future.
