Day One Rights Are Here – But What Happens Next for HR and the Interim Market?

Where Are We Now?

The Employment Rights Act 2025 is being implemented in stages throughout 2026 and 2027 as part of the Government’s wider “Plan to Make Work Pay“. Several reforms are already in force, including:

• Day one entitlement to paternity leave and unpaid parental leave
• Changes to Statutory Sick Pay, extending eligibility and removing waiting periods
• Stronger whistleblowing protections
• Increased collective redundancy protections
• The creation of a Fair Work Agency to strengthen enforcement of employment rights

Further changes are scheduled over the next 18 months, including enhanced protection against workplace harassment, wider trade union reforms and changes to unfair dismissal protections.

While the detail continues to evolve through consultation, the direction of travel is clear: greater protection for employees and increased responsibility for employers.

More Than a Compliance Exercise

For many HR teams, these changes arrive at a time when resources are already stretched.

Against that backdrop, employment reform presents a significant operational challenge.

Policies need updating. Contracts need reviewing. Managers need training. Employee relations frameworks need strengthening. Processes around onboarding, absence, family leave and performance management may all require scrutiny.

None of these activities are particularly glamorous, but getting them wrong could expose organisations to legal, financial and reputational risk.

Will Day One Rights Change Hiring Behaviour?

Some commentators have suggested that increased employee protections could make employers more cautious when recruiting.

The reality is likely to be more nuanced.

Good organisations already focus on robust recruitment processes, effective onboarding and strong management practices. However, where organisations may feel pressure is in ensuring those processes are consistently applied and properly documented.

In other words, the legislation isn’t necessarily changing what good HR looks like. It is raising the importance of getting the basics right every time.

For HR leaders, that means balancing compliance with commercial reality. Few organisations can afford to slow growth because they are overwhelmed by legislative change.

What Does This Mean for the Interim HR Market?

This is where I expect we will see a noticeable shift.

Periods of regulatory change often create increased demand for specialist interim expertise. Not because internal HR teams lack capability, but because they lack capacity.

Most HR functions are already managing transformation initiatives, workforce planning challenges, wellbeing priorities and recruitment activity. Adding major legislative reform into the mix inevitably creates additional pressure.

As a result, I believe demand for interim HR professionals will increase across several areas.

HR Change and Transformation

Many organisations will need support translating legislation into practical action plans. Experienced HR interims can lead policy reviews, implementation programmes and organisational readiness projects without creating long-term fixed costs.

Employee Relations Specialists

As employee protections expand, employee relations expertise becomes increasingly valuable. Organisations may seek interim support to manage complex casework, mitigate risk and coach managers through difficult situations.

HR Project Delivery

Not every organisation requires a permanent senior hire. Sometimes what is needed is a highly experienced HR professional who can deliver a specific project, leave behind sustainable processes and then step away.

Workforce Planning

Many employers are reassessing how they structure their workforce and deploy talent. Interim HR leaders can provide strategic insight while helping organisations remain agile during periods of uncertainty.

Why Interim HR Solutions Can Add Value

The most successful interim assignments are rarely about filling a vacancy.

They are about providing targeted expertise at a critical moment.

An experienced interim HR professional can offer:

• Immediate access to specialist knowledge
• Additional capacity during periods of change
• An objective external perspective
• Practical implementation experience from multiple organisations
• Reduced risk during complex transformation activity

Importantly, interim support should complement internal HR teams, not replace them.

The best outcomes happen when interims work alongside HR leaders, sharing knowledge, transferring capability and helping organisations navigate challenges without creating dependency.

A Strategic Opportunity for HR

It would be easy to view these reforms purely through a compliance lens.

However, there is a bigger opportunity here.

Many of the organisations that successfully navigate legislative change will also improve employee experience, strengthen management capability and build greater trust across their workforce.

Those outcomes are valuable regardless of the legal backdrop.

The organisations that act early are likely to spend less time reacting and more time focusing on strategic priorities.

As HR professionals, we’ve always balanced people, risk and commercial outcomes. The Employment Rights Act simply raises the stakes.

The challenge now is ensuring HR teams have the support, expertise and bandwidth to respond effectively.
