The Employment Rights Bill has become law. It received 'Royal Assent' on 18 December 2025. This is when the King formally agreed to make the Bill into an Act of Parliament (Employment Rights Act 2025).
The Act will introduce additions and amendments to existing legislation, including the Employment Rights Act 1996.
The employment law changes included in the Act will take place over a period of 2 years. Most changes will happen in 2026 and 2027.

What's already changed
One change took place as soon as the Bill became law.

Rules around 'minimum service levels' for strikes were removed on 18 December 2025. These rules were about keeping services running when there's a strike.
February 2026 changes
These changes will happen in February 2026, which is 2 months after the Bill became law.
Increased dismissal protection for industrial action
Dismissal for taking part in industrial action will become 'automatically unfair'. This will remove the current 12-week limit for claiming unfair dismissal. This will change in February 2026.
Trade union activity
These changes will happen in February 2026:
- the time needed to give notice of industrial action will reduce to 10 days, instead of 14 days

Whistleblowing protections for sexual harassment
Sexual harassment will become a 'qualifying disclosure' under whistleblowing law. This will mean protection from detriment and unfair dismissal for whistleblowers making a sexual harassment disclosure. This will change in April 2026.
Gender pay gap and menopause action plans
Employers will need to create action plans around menopause and gender pay gaps. These will be voluntary from April 2026. They will become mandatory sometime in 2027.
More trade union changes
These changes will happen in April 2026:
- simplifying how a trade union can gain recognition in a workplace
- allowing trade union members to vote electronically
Fair Work Agency
The Fair Work Agency will be established in April 2026, to:
- bring together existing enforcement bodies
- take on enforcement of other employment rights, such as holiday pay and statutory sick pay
October 2026 changes
Dismissal and rehire
Dismissing someone then rehiring them on worse terms and conditions will become an automatically unfair dismissal in most cases. This is sometimes known as 'fire and rehire'. This will change in October 2026.
Harassment
These changes will happen in October 2026:
- employers will be liable for harassment from third parties, for example customers or clients, unless they have taken all reasonable steps to prevent it happening – this will apply to all types of harassment
- employers will need to take 'all reasonable steps' to prevent sexual harassment – current law says 'reasonable steps'
A change to the law around non-disclosure agreements (NDAs) is also expected. This will void clauses that would prevent workers from alleging or disclosing work-related harassment or discrimination. The date of this change is not known yet.
Tipping
Tipping law will change in October 2026. Employers will need to:
- consult with workers or their representatives before creating a tipping policy
- update their tipping policy every 3 years
Employment tribunal time limits
Time limits for making a claim to an employment tribunal will increase to 6 months for all claims. The current time limit for most claims is 3 months. This will change in October 2026.
More changes to trade union rules
These trade union changes will happen in October 2026:
- a new duty for employers to inform workers of their right to join a trade union
- updated rules on a trade union's right of access to the workplace
- a new right to reasonable accommodation and facilities for trade union representatives carrying out their duties
- a new right to time off for union equality representatives to carry out their duties
Increased protection against detriment for industrial action
Workers taking part in industrial action will be protected against detriment, in addition to unfair dismissal. 'Detriment' is when someone is treated less favourably by their employer. This will change in October 2026.
Public sector outsourcing 'two-tier code'
There will be new measures for public sector outsourcing. This is to avoid having different terms and conditions for ex-public sector employees and private sector employees. This will change in October 2026.
New Adult Social Care Negotiating Body
There will be a new negotiating body for adult social care. This will start in October 2026.
December 2026 change
One change will happen in December 2026. It's specific to the seafarer industry.
Mandatory Seafarer's Charter
There will be a new mandatory charter for seafarers, with higher standards around health and safety, pay, job security and rest breaks. This will happen in December 2026.
2027 changes
The government has not announced when in 2027 most of these changes will happen.
Unfair dismissal
Protection from unfair dismissal will become a right after 6 months of being in a job. Currently, someone must have worked for their employer for 2 years before claiming unfair dismissal. This will happen in January 2027.
Protection from unfair dismissal was previously expected to become a right from the first day of employment. The government changed this before the Bill became law.
Increased pregnancy and maternity rights
The Act will strengthen protections against dismissal for pregnant workers and those returning from maternity leave. This will happen in 2027.
Bereavement leave
There will be a new right to statutory bereavement leave. It's not known yet whether this will be paid or unpaid leave. This will happen in 2027.
Zero-hours contracts
Workers on zero-hours contracts will get the right to guaranteed working hours, if they want them. This will happen in 2027.
Compensation for cancelled shifts
Workers will have the right to be paid if a shift is cancelled, moved to another date, or cut short by an employer. This will happen in 2027.
Flexible working
There will be an amendment to flexible working law in 2027. If an employer rejects a flexible working request because of a genuine business reason, they will have to:
- state the reasons
- explain why they believe their refusal is reasonable
Doing this is already good practice. But it will become a legal requirement.
Further harassment change
The law will specify what 'reasonable steps' means when preventing sexual harassment, following earlier changes in October 2026. This change will happen in 2027.
Mandatory gender pay gap and menopause action plans
Action plans around menopause and gender pay gaps will become mandatory, following their voluntary introduction in April 2026. This change will happen in 2027.
Collective redundancy
These collective redundancy changes will happen in 2027:
- employers will need to consider the total number of redundancies across their whole organisation, not just individual workplaces – currently, collective redundancy rules only apply to individual workplaces
- increased collective redundancy protection for workers on ships that regularly operate from British ports but are registered outside Great Britain
2027 trade union changes
These trade union changes will happen in 2027:
- extending laws that protect trade union members from discrimination and being 'blacklisted'
- a new industrial relations framework, to help employers and trade unions work together
Regulation of umbrella companies
The definition of agencies will be expanded to include 'umbrella companies'. This will allow enforcement by the relevant bodies. This change will happen in 2027.
