A Comprehensive Guide for UK Workplaces

The landscape of UK employment law has officially shifted. Following months of debate and anticipation, the Employment Rights Bill received Royal Assent on 18 December 2025, formally becoming the Employment Rights Act 2025 (the “Act”). This legislation represents the most significant overhaul of worker protections in a generation, fundamentally increasing the obligations of employers along with the rights of employees.

For businesses and workers alike, the period of speculation is over. While the Act is now law, the rollout is phased, with critical changes taking effect throughout 2026 and 2027. Understanding these timelines and the distinction between what is fixed in statute and what remains subject to consultation is vital for compliance and strategic planning.

This guide details the key provisions of the Act and explores the implications for the labour market, including how these changes will impact daily operations.

The Employment Rights Act 2025 – A Summary

The key points include the reduction of the ordinary unfair dismissal qualifying period to six months, the removal of the upper limit on compensation for successful unfair dismissal claims, the removal of the three-day wait for Statutory Sick Pay, the requirement to offer guaranteed hours contracts to workers who demonstrate a regular pattern of work under variable-hours arrangements, expanded family-friendly rights and increased employer liability for third-party harassment as well as collective redundancy consultation.

What is the Aim of the Legislation?

The primary aim of the legislation is to raise the baseline of worker protections, reduce insecure work and to modernise the frameworks for trade unions as well as existing enforcement processes. By addressing “one-sided flexibility,” the government intends to create a fairer, more productive economy.

It is crucial to note that while the Act has passed, not every provision applies immediately. The government is currently consulting on specific implementation details (such as the exact mechanics of the right to guaranteed working hours for workers on zero-hours contracts). This means that while the principle is law, the finer details of how rights should work in practice are still subject to further consideration.

Key Provisions of the Employment Rights Act 2025

What are the key changes introduced by the Act? The Act covers a vast array of areas, from dismissal protections, to discrimination and family leave. Below is a summary of what are considered to be some of the most significant changes.

Stronger Protection Against Unfair Dismissal

Perhaps the most discussed change involves the qualifying period for unfair dismissal rights. As things currently stand, the default position is that employees have to work for two years before gaining ordinary unfair dismissal rights. Changes are also going to be made to the statutory cap on compensation for unfair dismissal claims.

• Qualifying Service Change: From 1 January 2027, protection from ordinary unfair dismissal will become a right after six months of employment.
• Compensation Upper Limit Change: Also, from 1 January 2027, the statutory cap on compensatory awards for successful unfair dismissal claims, currently £118,223 or twelve months’ pay (whichever is the lower) will be removed.
• The Impact: This significantly reduces the window employers have to assess suitability of new members of staff without the potential risk of ordinary unfair dismissal claims. Alongside the statutory cap on compensatory awards being removed, these updates will increase the financial stakes for non-compliant dismissals by employers, particularly in cases involving high earning employees.

Restrictions on “Fire and Rehire”

The practice of dismissing employees and re-engaging them on inferior terms and conditions, often referred to as “fire and rehire”, faces strict new controls.

• The Change: From October 2026, dismissing an employee because they refuse to agree to a restricted variation of their contract, such as reductions to pay or pensions, or changes to hours, shifts or time‑off; and re‑engaging them on less favourable terms, will generally constitute an automatic unfair dismissal, subject to narrow statutory exceptions. It will also become automatically unfair to dismiss an employee where the main reason is to replace them with someone else, or to re-engage them, on new terms relating to entitlements including pay, pension, hours of work or holiday entitlement.
• Exceptions: There are limited circumstances where the new rules will be exempt, where a business relies on restructuring to prevent total collapse and genuinely has no alternative. However, the burden of proof in such cases will be high. This will compel employers to seek genuine agreement on contract variations rather than forcing them through via dismissal and re-engagement.

Tackling Zero-Hours Contracts and Shift Cancellations

Addressing insecure work is a cornerstone of the Act. These changes are expected to take effect in 2027.

• Guaranteed Hours: Workers on zero-hours or low-hours contracts will gain the right to a contract with guaranteed hours if they work regular hours over a specific reference period (likely to be 12 weeks), provided that the worker’s hours exceeded the minimum number specified in their contract.
• Shift Cancellation Compensation: Workers will have the right to be paid if a shift is cancelled, moved, or cut short on little notice. This moves the financial risk of fluctuating demand from the worker back to the employer.
• Consultation Status: The government is currently consulting on the specifics of the reference period, the amount of the cancellation payment and what constitutes “reasonable notice”.
• Agency Workers: These rights will also extend to agency workers. It is intended that the hirer of agency workers will be responsible for offering regular hours contracts, with the agency being responsible for shift cancellation payments.

Reforming Statutory Sick Pay (“SSP”)

To support public health and worker welfare, the rules regarding sick pay are becoming more generous starting in April 2026.

• Day One Right: SSP will be payable from the first day of work missed due to illness, removing the existing three-day waiting period.
• Eligibility: The Lower Earnings Limit will be removed, meaning almost all part-time and lower-paid staff will be eligible for sick pay immediately. This will represent a direct cost increase for employers, especially impacting organisations with large part-time workforces.

Expanded Family-Friendly Rights

The Act strengthens the safety net for parents and carers, with changes rolling out between April 2026 and 2027, including:-

• Paternity and Parental Leave: From April 2026, paternity leave and unpaid parental leave become “day one rights”. Employees no longer need 26 weeks of service to qualify.

• Enhanced Protection from Dismissal: The dismissal of employees during pregnancy, maternity, adoption or shared parental leave, or within 6 months of their return to work will be unlawful, except in certain circumstances (to be set out in future regulations).

• Bereavement Leave: In addition to the existing right to parental bereavement leave, a new statutory right to bereavement leave will be introduced in 2027. This will create a separate day-one right to unpaid bereavement leave for employees who experience loss of a family member, including pregnancy loss before 24 weeks.

Modernising Trade Union Law

The Act aims to simplify how unions operate and engage with workers.

• Recognition: The process for unions to gain statutory recognition in a workplace will be simplified starting from April 2026.
• Access: This section of the Act mandates that employers must inform workers of their right to join a trade union when they provide them with a section 1 statement of employment particulars. It also grants union representatives greater access to workplaces to support members and facilitate recruitment. Ballot and notice requirements will also be reduced.
• Industrial Action: The Act has removed minimum service levels for strikes (already effective) and will increase protections for workers participating in industrial action.

Collective Redundancy Consultation

Risks associated with collective redundancies are also set to increase for employers. Namely:-

• Additional Threshold: An additional threshold test will be introduced (to be clarified in future regulations) which will result in collective consultation requirements being prompted more easily.
• Increased Penalty: The maximum penalty for non-compliance with the collective consultation obligations will increase significantly from 90 days’ pay to 180 days’ pay per affected employee.

Harassment at Work

From October 2026, further steps will be taken to strengthen protections relating to harassment at work including:-

• Third-Party Harassment: Employers will be liable for harassment of their staff by third parties (e.g. customers and suppliers) of any kind unless they take “all reasonable steps” to prevent it.

• Whistleblowing Protection: A complaint of sexual harassment at work will be treated as a protected disclosure under whistleblowing legislation.

• Confidentiality Restrictions: Confidentiality provisions and Non-Disclosure Agreements will not be permitted to prevent employees from discussing allegations of harassment and/or discrimination.

The Fair Work Agency

To ensure that these new rights are upheld, a new enforcement body, the Fair Work Agency, will be established in April 2026. This agency consolidates existing bodies and holds powers to enforce holiday pay, statutory sick pay and minimum wage compliance, providing a “one-stop shop” for enforcement.  It will have considerable powers including the enforcement of failures to make statutory payments and to impose penalties.

Whilst the above serves as summary of the most material new rights, this is not an exhaustive list with further changes intended including in relation to flexible working and equality reporting.

Implications for Employers

The Employment Rights Act 2025 requires immediate strategic thinking. Waiting until the implementation dates may leave businesses exposed.

Adjusting Policies and Procedures

Employers must conduct a comprehensive audit of working practices, current contracts, templates and handbooks, for example.

• Contracts: Will your contracts for casual workers be compliant moving forwards to reflect the new rules on guaranteed hours? If you rely heavily on zero-hours contracts, you will need to model the cost implications of offering guaranteed hours to regular staff.
• Probation: With unfair dismissal rights kicking in at six months instead of 2 years, probationary processes must be robust. Managers will need to identify performance issues early, typically within the first three or four months, rather than letting them drift past the six-month mark.

Training and Awareness

The increased liability, particularly regarding harassment will require employers to update their policies, procedures and templates, together with carrying out an audit of their practices.  In some cases, it may also demand a cultural change.

• Third-Party Harassment: As outlined above, going forward employers will be liable for harassment of their staff by third parties, unless they take “all reasonable steps” to prevent it. An example of some of the steps typically necessary to comply with this obligation would include visible policies, signage and tailored intervention training for managers.
• Manager Capability: Line managers are often the first point of contact for leave requests or disciplinary issues. They must be trained on the new rights to avoid any unintended non-compliance.

Managing Costs

Budgeting for 2026 and 2027 must account for increased operational costs, such as.

• SSP: The removal of waiting days and the Lower Earnings Limit will increase the wage bill.
• Tribunal Risks: With the cap on unfair dismissal compensation removed and the qualifying period shortened, the financial risk of a “bad exit” is higher. Investing in specialist advice before dismissing staff will more than ever become a cost-effective option rather than risking a tribunal claim.
• Contract and Policy Review: A number of the changes will require updates to be made to an employer’s contracts and internal policies.

Seeking Legal Advice

Disputes often arise when new laws interact with old practices and contracts.

With the Act introducing significant changes within a complex and evolving legal landscape, employers should take advice as early as possible to help navigate these challenges and avoid costly mistakes

Implications for Employees

For workers, the Act promises greater security and predictability, but understanding when these rights apply is key.

When do the new rights apply?

Employees should familiarise themselves with the timeline for implementation. For example, while the Act is now law, rights regarding shift cancellation payments do not apply until 2027. Protection from unfair dismissal after six months is a significant shift that offers greater job security, but only applies to new hires starting from January 2027 onwards.

Seeking Legal Advice

If an employer fails to adhere to the new statutory rights (such as refusing SSP from day one after April 2026), employees should seek professional advice.

Conclusion

The Employment Rights Act 2025 is not merely an update; it is a transformation of the framework governing the UK workplace. By shifting the balance of power regarding job security and flexibility, it demands that employers move away from reactive management towards a proactive approach with early intervention to manage risks, requiring more robust processes and documentation to be in place. For employers, the next 18 months are a critical window for preparation. Auditing contracts, practices and procedures, training managers and budgeting for new costs are immediate priorities. For employees, the Act signals a future where work is more secure and family life is better supported. Adapting to these changes is not optional—it is the new standard of business in the UK.
