This Act is a reform programme, not a single switch. Royal Assent made it law, but individual measures start on different dates. That distinction matters when a business updates a contract, handles leave or makes a dismissal decision.
Build the project around commencement dates. For each measure, record the legal start date, the business process affected, the document or system that needs changing and the person responsible.
The April 2026 package changed several everyday employment processes. Statutory Sick Pay no longer uses the lower earnings limit or waiting period in the same way, and day-one rights were introduced for paternity leave and unpaid parental leave. The collective redundancy protective award was also increased.
The official timetable then moves through union, harassment, tipping and enforcement measures later in 2026. Not every business will use every rule, but every employer should know which internal process owns the change.
Key points
The January 2027 timetable includes a six-month qualifying period for ordinary unfair-dismissal protection and stronger restrictions on dismissal and re-engagement. Later reforms are expected for guaranteed hours and shift notice.
For a small employer, the operational effect is straightforward: early performance conversations need to happen earlier, probation reviews need real dates and evidence, and variable-hours models need a deliberate review before the new rights commence.
Map the workforce
Identify employees in probation, variable-hours workers, agency arrangements and any roles likely to change.
Fix the manager process
Set probation review dates, document performance concerns and make escalation routes easy to use.
Update the documents
Align contracts, policies, letters and payroll settings with the rule that will apply.
Recheck before commencement
Confirm final regulations and official guidance before relying on the updated process.
Key points
No. The Act is being commenced in stages. Employers should check the date for the particular reform and any regulations or official guidance that support it.
Start with processes already affected in 2026, then work forward by commencement date. Sickness absence, family leave, probation, dismissal and variable-hours arrangements are sensible priorities for many employers.
That is risky. A shorter qualifying period makes early performance management and probation records more important. Contracts, manager training and review points should be updated before the new rules apply.
Employment Rights Act rollout reaches its 2026 implementation phase
The official implementation timetable now spans measures already introduced in April 2026 and further workplace reforms scheduled across October 2026 and 2027.
