Significant changes under the Employment Rights Act 2025 are now coming into force, with major implications for how employers handle complaints, probation and early dismissals. Two reforms in particular demand immediate HR attention.
From 6 April 2026, disclosures about sexual harassment are explicitly recognised as ‘protected disclosures’ under the whistleblowing legislation. Previously, a worker who reported sexual harassment in the workplace was primarily protected through the ‘victimisation’ provisions of the Equality Act 2010. Whilst the Employment Rights Act 1996 (as amended by PIDA 1998) already covered disclosures about breaches of a legal obligation (which could arguably encompass sexual harassment), the addition of sexual harassment as an express qualifying disclosure category removes any ambiguity and materially strengthens the position of individuals making these reports.
With the changes in place, most exposure will typically arise not from policy failures but from manager reactions to receiving complaints. The whistleblowing protections apply even if the complaints are not labelled as ‘whistleblowing complaint’.
Informal handling of sexual harassment complaints, defensive responses, or a poor separation between managing complaints and any subsequent disciplinary action will all create risks of claims.
From 1 January 2027:
Employers will have far less time to identify, manage and document underperformance before full unfair dismissal rights apply, significantly increasing financial and litigation risk.
Employers and HR teams need to act swiftly with new underperforming staff. It will no longer be safe to give new staff a long settling in period before assessing their performance or fit within the company.
These changes represent a cultural shift, not just a legal one. Earlier unfair dismissal rights and stronger whistleblowing protection mean employers must rely on good process, early intervention and confident, well-trained managers. For HR teams, this is now a business-critical capability.

What the changes in the Employment Rights Act 2025 could mean for your business.
As one of the most common contract types in retail, health & social care and hospitality sectors, the proposed changes to zero-hour contracts in the new Employment Rights Act 2025 will have significant implications for businesses.
The term zero-hour contract is often used interchangeably with part-time contracts but there are specific and important differences. Currently, under most zero-hour contracts:
Under the new Employment Rights Act 2025 there are broadly three changes which will have a significant impact on the use of zero-hours contracts:
Each of these are further explained below.
Staff on either zero-hour contracts or “low-hours” contracts who have worked regular hours over a “reference period” must be offered a contract with guaranteed hours “reflecting” those hours. Within this requirement there are a number of points which the Employment Rights Act does not define:
These points will be clarified following a formal consultation with key stakeholders. It is anticipated that “reference period” will be between 12 weeks and 6 months but we will have to wait to see the final proposals, likely to be ready by summer this year.
Following the initial “reference period”, businesses must offer the worker the average number of guaranteed hours that they worked during the “reference period”. This must be under new contractual terms guaranteeing those hours, and on the days/times or working pattern that were worked during the reference period.
The worker will have the option to either accept the new offer, or to keep the flexibility of their existing zero-hour contract. Businesses will have to continue to assess the hours worked by staff while they have “low-hours” contracts, after each further “reference period”. The duty to offer guaranteed hours continues at future reference points.
The changes once implemented will require businesses to inform their staff of their rights under the new guaranteed hours regime and keep them informed while they qualify.
Businesses will be required to give “reasonable notice” of shifts when offering them to zero-hour workers or shift employees. As with the guaranteed hours changes, the following details have not been defined:
These terms again will be defined following consultation, expected by the summer of 2026.
The new Act envisages setting a minimum amount of time that has to be provided when offering shifts to zero-hour staff. This however is not defined in the Act and the details will be part of the consultation process.
The requirement to provide “reasonable notice” will also apply to employees who are on rota shift contract, which is where the hours of work are set but the days and pattern of work can vary at the business’s discretion.
Where businesses fail to provide “reasonable notice” for the shifts, the worker can bring a claim to the Employment Tribunal and compensation will be assessed on what the Tribunal “considers just and equitable in all the circumstances to compensate the worker for any financial loss sustained by the worker which is attributable to the matter complained of.” This could lead to claims including bank overdraft charges or credit card late payment fees which the worker faces when a shift they expected is not offered to them.
Under the new Act, businesses will have to provide “reasonable notice” of a change or cancellation of a shift which had been accepted by the zero-hour staff. Again, what is meant by “reasonable notice” is still to be defined.
In addition to the requirement to provide “reasonable notice” of changes or cancellation of shifts, the Act introduces the right to compensation for zero-hour staff if their shift is cancelled, moved or curtailed at “short notice”. The zero-hour staff will be entitled to a payment every time there is “short notice” of a cancellation or change of shift. Further, the payment will have to be paid to the staff within a specific time frame.
As with all of the above upcoming changes, the devil will be in the detail, and the Act is yet to define:
The Act does specify that “short notice” for cancelling a shift will be less than 48-hours before the proposed shift start time. The meaning of “short notice” when moving a shift or reducing a shift will be set by Government after consultation.
Businesses can still be caught by the new regime even if they do not use zero-hour or “low-hour” workers. The new requirements will apply equally to agency workers.
With agency workers, both the end user hirer and agency will have equal responsibility for providing the worker with the necessary notice of changes to shifts. However, the changes specify that is is the agencies which will be responsible for paying the agency worker and have the ability to recoup the cancellation and short notice fee from the end user, subject to the commercial terms of the agreement between the end user and agency.
While the Employment Rights Act 2025 became law on 18 December 2025, the Government has confirmed they will not be implementing these changes immediately. There remains a significant number of specific details to be clarified. Under the Governments current timeline, which updated in February 2026, there is to be a period of consultation on these details, with the changes likely due to come into effect in 2027.

The UK employment tribunal compensatory award cap has until now limited financial exposure for unfair dismissal claims. That certainty is soon disappearing. Once the cap is removed, tribunals can award losses reflecting an executive’s actual full earnings including base salary, long notice periods, discretionary bonuses, and long-term incentives. For senior executives, claims could easily reach seven figures.
This change will fundamentally affect how Boards manage senior exits. Informal processes, limited performance documentation, and reliance on ‘loss of confidence’ are no longer safe. Tribunals will examine whether dismissals were reasonable and evidenced, and may ask what would have happened if the employer had acted fairly, considering potential performance outcomes, bonuses, and incentive awards. Even discretionary bonuses could now become part of claims.
The implications are Board-level, not just HR. So, what do Boards need to consider going forward?
Boards which are unprepared for this shift risk material financial exposure, reputational harm, and potential for high-stakes litigation. The removal of the cap is not just a legislative change but a call for Boards to elevate performance management, governance discipline, and deeper risk assessments.
With significant experience in advising Boards on people-risk, executive remuneration, and governance, I see this as a pivotal moment for leadership accountability. Boards that act now will safeguard both people and organisational reputation, while strengthening confidence in making difficult but necessary leadership decisions.
