UK Employment Rights Act: How will changes to individual rights reshape everyday work?
With changes to individual employment law rights already in effect, and more on the horizon, their impact will be felt largely through everyday workplace interactions. Where are organisations most likely to underestimate that impact, and what actions can you take now?
As the “once in a generation” series of measures introduced by the 2025 UK Employment Rights Act1 continue to unfold — with phased consultation and implementation due over 2026 and 2027 — they will affect different employee groups in different ways.
Our previous article explored how to move from awareness to readiness while there is still ambiguity around what will be introduced.
Here, we’re examining:
- What the changes mean for employees in practice
- How to ensure these are implemented effectively
- How they might reshape and strengthen the wider employer-employee relationship.
An opportunity to be more deliberate
Employees are likely to experience these measures through everyday moments: calling in sick, requesting flexibility, completing probation, or having performance conversations. It’s in these moments that policy becomes experience.
Success will depend on how consistently organisations apply the changes through thousands of individual decisions. Although the legislation doesn’t require a wholesale reinvention of the workplace overnight, it does place expectations of fairness and transparency under the spotlight.
Some employers may focus only on compliance: update policies, brief HR, send minimum communication, move on. Others will recognise a wider opportunity to be more deliberate — strengthening employee experience by applying policies coherently, communicating decisions clearly, building greater trust across the organisation, all while demonstrating fairness and transparency.
Today, employers are increasingly judged on their ability to demonstrate fairness. Mercer’s latest Inside Employees’ Minds study found that fair pay now outweighs competitive pay as a reason people stay with organisations, while unfair pay is the top reason people leave.
There are four important aspects to consider:
-
Understanding and interpretationThe measures are broad, evolving, and subject to further consultation. It’s important to understand the legal changes, but also the intention behind them and their strategic, operational, and cultural implications.
-
Scale and pace of changeThis is a wide-ranging, phased programme with ongoing consultation. It needs continual adjustment, rather than a “one and done” approach.
-
Employee experiencePolicy does not guarantee consistency. Employees will experience them differently depending on their role, manager, life stage, and circumstances. As the point where policy becomes practice, managers’ judgement and consistency will increasingly shape employee experience.
-
Communication and clarityEmployees need simple, human explanations of what is changing, what it means for them, and what they need to do. Organisations also need to think carefully about how they reach a diverse and distributed workforce (including remote, hybrid, frontline, agency, or contingent employees), and ensure messages are inclusive, consistent and trusted by all employee groups.
Where will the changes be felt?
For individuals, the Act is designed to:
- Strengthen protections
- Reduce vulnerability
- Elevate worker voice
- Create greater fairness in how people experience work.
For employers, it creates a more visible and closely scrutinised employment relationship. Day-one rights place stronger emphasis on decision-making from the outset, while flexibility continues to move to the centre of people’s expectations. Employees are also increasingly likely to question inconsistencies, so variation between teams will be difficult to justify.
But consistency does not mean treating every situation identically. It means making fair, transparent decisions aligned with organisational principles. There is also an important DEI dimension here, as policies may not all be experienced equally. So where might discrepancies show up?
Four areas of impact
Although created centrally, and often also shaped through consultation with trade unions and employee representatives, policies are ultimately interpreted through human judgement — usually managers responding in real-time, often under pressure.
Managers are therefore where many of the policies will become tangible for employees, as the first point of contact for requests and conversations. Decisions are happening earlier, requiring greater judgement and communication, and carrying more visibility. This is particularly important where issues arise from the first day of employment, such as job offers, probation or workplace concerns.
Managers are employees too, so they need to understand what the changes mean personally before they can explain them confidently to others. Without clarity and support, inconsistency becomes more likely. While they don’t need exhaustive legal knowledge, they do need confidence in how to approach decisions, when to involve HR, and the role they play in shaping how policies come to life.
Practical steps:
- Keep guidance simple and usable, not overly legalistic or process-heavy, while supporting accurate documentation
- Provide practical tools like scenarios, talking points, and FAQs
- Clarify where discretion is appropriate and where consistency is non-negotiable
- Reinforce managers’ accountability for applying the measures fairly
- Regularly gather feedback to evaluate tools and training and identify ongoing support needs.
Changes to sick pay and absence rights raise broader questions around wellbeing, workforce participation, and how employers support people to remain healthy and productive in work. At a time when fewer employees are thriving — Mercer’s latest Global Talent Trends found thriving (prospering in terms of health, wealth and career) has fallen from 66% in 2024 to 44% globally in 2026 — these issues are becoming harder to ignore.
Day-one statutory sick pay may help address long-standing presenteeism, but also introduces new tensions around absence patterns and manager capability. Employers may underestimate the behavioural impact, particularly how managers respond to short-term absence and whether employees feel comfortable discussing health concerns.
For some, the focus may be on misuse or increases in short-term absence. For others, this may encourage employers to think more proactively about workforce health and support people to stay economically active for longer.
This is particularly relevant for employees with:
- Chronic conditions
- Episodic illness
- Menopause symptoms
- Caring responsibilities
- Other life-stage challenges.
It places greater emphasis on earlier intervention, return-to-work conversations, and clearer pathways into wellbeing and occupational health support before issues escalate.
Benefits play an important role here. Many organisations already provide employee assistance programmes (EAPs), occupational health, wellbeing services and virtual GP access, yet employees are often unaware these services exist or are unsure how to use them.
Absence management can therefore become a weak link, particularly where patterns are only addressed once employees are already struggling. Over the long-term, shifting from “cure” to “prevention”, supported by earlier intervention, can help create more sustainable and healthier work environments.
Practical steps:
- Frame absence as part of wellbeing and workforce sustainability, not just managing attendance
- Encourage earlier return-to-work and wellbeing conversations to identify underlying issues and support needs
- Help employees understand what support is available and how to access it.
Flexibility is now an established part of working life. Gone are the days when it was seen as an occasional “perk” or accommodation. Yet experiences vary widely across sectors, with customer-facing or operational environments facing greater implementation challenges.
Handled well, flexibility can be a powerful inclusion lever. Handled poorly, it can create perceptions of unfairness through inconsistent decisions or the practical realities of different roles. While not every job can offer the same flexibility, the measures may prompt employers to think more creatively about how work is organised and where greater flexibility is possible.
This is especially relevant for:
- Workers on zero hours arrangements
- Agency workers
- Those balancing work with caring needs or parental leave.
There’s also a risk that employees see flexibility as a trade-off for progression or pay, because they feel “lucky” to have it, even when they deserve the same opportunities as colleagues working more “traditionally”. This makes transparency critical. Employees are more likely to trust decisions when they understand the rationale behind them.
Practical steps:
- Explain how flexibility decisions are made and what criteria are used
- Be transparent about what flexibility is and isn’t possible across different roles and teams
- Introduce governance to promote consistency across teams
- Monitor whether flexible working affects career progression, pay, performance or visibility.
Many employers offer extensive benefits and support programmes, but this doesn’t automatically mean employees experience work as supportive. This is where the gap between intent and reality often shows. Mercer’s Inside Employees’ Minds research demonstrates that only 12% of employees describe their organisation as having a genuinely “healthy culture”, while many are unaware of the support available.
Employees may have flexibility, wellbeing initiatives, and development opportunities on paper, yet still encounter barriers. Support can be hard to navigate, policies may be interpreted differently by individual managers, or organisations may assume employees understand them simply because they have been shared.
Employees need to know what support exists, when to use it, and how to access it — and communication needs to feel accessible and grounded in their everyday working reality. Managers play a pivotal role in reinforcing these messages and helping employees translate policy into practice.
In some sectors, employers may also need to consider how employee voice is expressed through consultation structures, trade union recognition, or even industrial action - an area we explore later in this series. It’s also important to consider how workplace policies affect client relationships and service delivery.
Practical steps:
- Use simple, employee-centred language rather than HR or legal terminology
- Ensure support is easy to access and navigate, particularly for frontline or shop-floor employees
- Reduce unnecessary complexity between policies and ways to access support
- Translate policy commitments into clear, visible actions that employees can access
- Test whether employees understand what support is available and feel confident using it
What can employers do now?
While many organisations are waiting for greater certainty, there is an opportunity to get on the front foot now. As the detail of the Act continues to evolve, use this moment to step back and think more holistically about how work is experienced across the employee lifecycle. Where does friction already exist? Where might the measures expose variations or weaknesses?
Practical steps include:
-
Map the measures against the employee lifecycle to identify who may be affected and when
-
Recognise that support needs differ across life and career stages
-
Test policies through realistic operational scenarios, including workload, rest breaks and line manager discretion
-
Review absence, flexibility, probation, and performance processes against the measures
-
Assess manager readiness and capability
-
Review existing wellbeing and benefits provision before introducing more support
-
Monitor employee experience and gather feedback to identify inconsistencies
Data and insight will become increasingly important. Employee listening can help you identify emerging concerns, while tracking requests, approvals and outcomes can surface unevenness. It may also help you to identify where excessive local control or inconsistency is creating avoidable friction.
Collecting data alone is not enough; people need to see visible action in response to feedback. As oversight and enforcement increase, including through the Fair Work Agency2, trust will increasingly depend on organisations demonstrating that they listen and act.
Finally, develop a clear change narrative that explains what the legislation is, what it means for employees, and how support can be accessed. During periods of uncertainty, people need clarity and evidence of genuine commitment to their best interests.
A more intentional approach to work
While policies may appear straightforward, the real test lies in how they’re interpreted and applied across different situations.
The challenge for HR and leadership is to ensure decisions align with both the intent of the legislation and broader expectations of fairness and transparency. That requires closer attention to the influences shaping those decisions:
- Clarity of guidance
- Communication
- Support structures
- Governance
- Ongoing employee listening
- Manager capability.
It also means understanding where managers have appropriate control, and where greater consistency or escalation is needed.
Ultimately, these measures are about how work is experienced day-to-day. In recognising this, organisations should be better positioned not only to implement the changes effectively, but also to use them as a catalyst for being more intentional about how work looks and feels for people.
