The Employment Rights Bill (ERB) represents the most significant shake-up of UK employment law in decades. For employers, the changes introduced will bring both responsibilities and opportunities. This handbook is designed to help you navigate the what, when and how of the reforms, so you can act strategically and compliantly, not reactively.
In this guide, we’ll cover:
- The purpose and scope of the Bill
- Key changes employers must know
- A phased timeline of implementation
- What you need to do now to prepare
- Pitfalls and challenges to watch
- Next steps and practical actions
1. What is the Employment Rights Bill and why it matters
The Employment Rights Bill is a broad package of proposals intended to modernise and strengthen workers’ rights, reflecting changes in how we work today. It aims to amend existing legislation, notably the Employment Rights Act 1996 and related statutes, to bring in new protections and obligations.
In short, this isn’t a tweak: it’s a reset. Employers who treat it as “business as usual” risk non-compliance, reputational harm, legal claims and conflict with employees.
2. Key changes employers must know
Below is a summary of some of the most significant proposed changes in the Bill. Bear in mind: provisions may still evolve as the legislation passes through Parliament.
Employment from day one
- Some employment rights will apply from day one, rather than after a qualifying period.
- Paternity leave, ordinary parental leave and other family rights could become day-one rights.
Statutory Sick Pay (SSP) changes
- Removal of the “waiting days” means SSP is expected to be payable from the first day of illness, replacing the current rule of payment from day four.
- The lower earnings limit for SSP eligibility may be abolished.
Unfair dismissal & protection for industrial action
- Dismissal for participating in industrial action is proposed to become automatically unfair, removing the current 12-week limitation.
- The removal of minimum service level rules for strikes is expected.
- Notice periods for industrial action may be reduced; ballots simplified.
Fire-and-rehire practices
- The Bill is expected to make dismissing and rehiring an employee on worse terms (i.e. “fire and rehire”) automatically unfair in most cases.
Probation, lighter dismissal procedures & “statutory probation”
- A new statutory probationary period is proposed during which a lighter dismissal process may apply.
- Employers may need to update their probation, disciplinary and performance management policies to align with the new rules.
Whistleblowing/harassment disclosures
- Sexual harassment is likely to become a “qualifying disclosure” under whistleblowing protections, meaning employees are better protected for raising such matters.
Gender pay gap, menopause and reporting
- New obligations may be introduced on gender pay gap action plans and menopause strategies, initially on a voluntary basis, later potentially becoming mandatory.
NDAs and confidentiality in misconduct cases
- The Bill is expected to prohibit the use of non-disclosure agreements in cases of workplace harassment and discrimination, rendering them void in that context.
3. Phased timeline: when the changes take effect
Understanding when each change comes into force is crucial for planning. The reforms are expected to roll out over several phases:
| Phase | Timing (expected) | Key changes / remarks |
| Royal Assent | Autumn 2025 | The Bill becomes law, enabling immediate changes such as removal of certain strike rules and industrial action protections. |
| Autumn 2025 (plus months thereafter) | Shortly after Royal Assent | Some trade union/industrial action reforms (ballot rules, notice periods) come into effect. |
| April 2026 | Next major phase | Introduction of changes to SSP, parental leave, probation, whistleblowing, collective redundancy awards, etc. |
| October 2026 (or later) | Later changes | Fire-and-rehire protections expected to take effect. |
Note: Some reforms (e.g. probation, lighter dismissal) may be delayed until later, pending further regulations and consultations.
Because the Bill is still progressing through Parliament, timing and final detail remain subject to change.
4. How employers should prepare (your to-do checklist)
Here’s a practical roadmap you can follow to ensure your organisation is ready.
Conduct an impact audit
- Map which current policies, contracts, handbooks or practices may become non-compliant under the new rules.
- Identify high risk areas: probation, sick pay, dismissal, parental leave, redundancy, harassment policies.
- Assess how many employees might be affected (e.g. those with less than 1 year service).
Update policies, contracts and handbooks
- Revise your probation, disciplinary, dismissal and performance management policies in anticipation of lighter dismissal requirements.
- Adjust SSP policy and absence procedures to remove waiting days.
- Update family leave policies to allow earlier access.
- Review and remove or amend any NDA/confidentiality clauses that might conflict with new rules.
- Ensure handbook and contract wording is flexible enough to accommodate transitional or phased change.
Training and internal communication
- Train line managers, HR teams and people leaders on the new rights, constraints and required handling.
- Communicate with employees: consider an internal FAQ or newsletter explaining upcoming changes and how the business is adapting.
Monitor legislative updates
- Subscribe to government updates, legal bulletins, ACAS notifications.
- Keep an eye on the passage of the Bill, amendments and draft secondary regulations.
- Liaise with your legal advisors or external HR consultants for clarifications.
Phased implementation planning
- Determine when you will roll out revised policies (e.g. aligning with April 2026).
- Pilot changes in lower-risk areas first.
- Build a compliance calendar, with milestones for each major change.
Risk management and scenario planning
- Model financial and operational impact (e.g. increased SSP costs, potential rises in tribunal claims).
- Plan for communications if employees question or challenge changes.
- Consider legal defence strategies: ensuring you can evidence fair process, legitimate business reasons, consistent treatment.
5. Key risks, challenges & pitfalls
No reform of this scale is without its challenges. Be vigilant to avoid:
- Overconfidence: assuming your existing policies “cover everything” – many changes are material and will need explicit rewriting.
- Lagging implementation: delaying updates until the last moment leaves you exposed.
- Unclear communication: staff misunderstanding “day one rights” or “lighter touch dismissal” can lead to morale issues or disputes.
- Inconsistent application: applying new rules unevenly across teams/departments may open claims of unfair treatment.
- Underestimating cost: more generous sick pay, removing eligibility thresholds or expanded leave rights may increase your costs materially.
- Dependency on future regulations: some key details (e.g. exact process for lighter dismissal) are not finalised and await secondary legislation.
- Watching for unintended quirks: e.g. interactions with other laws (e.g. Equality Act, Working Time, redundancy consultation) must be thought through.
6. Next steps & recommended actions
To stay ahead and be ready:
- Set up a dedicated project team (HR, legal, finance) responsible for ERB readiness.
- Create a timeline and project plan aligned with anticipated phases (e.g. Autumn 2025, April 2026).
- Schedule policy reviews and updates at least 6–9 months ahead of major change dates.
- Budget for additional costs, including training, legal advice and increased leave/absence pay.
- Engage and educate leadership so that senior managers understand the strategic and compliance implications.
- Stay flexible – monitor how the Bill evolves in Parliament and be prepared to adapt.
- Audit and test your new approaches in low-risk settings before full rollout.
