How to build an effective HR team during public sector organisational change

Public sector employers are no longer dealing with change as an occasional project. For many, it is now a constant pressure running alongside financial challenge, service delivery demands and workforce risk. 

Local government reorganisation and devolution are reshaping councils and combined authorities. NHS organisations are reviewing structures, redesigning roles and making difficult workforce decisions. Academy trusts are restructuring central teams, while housing associations, universities and charities continue to respond to funding pressures, regulatory change and changing employee expectations. 

In conversations with public sector leaders, the challenge is rarely identifying whether change is coming. They already know it is. The more urgent question is whether their HR function has the capacity, confidence and specialist expertise to support that change before pressure starts to build. 

In some cases, organisations only review their HR resource after consultation is approaching, employee relations activity has increased or internal teams are already stretched. By that stage, leaders are trying to secure specialist support quickly while managing sensitive workforce decisions, maintaining services and keeping employees informed. 

Reviewing HR capacity earlier gives organisations more control. It helps leaders identify the skills they need, decide what can be managed internally and determine whether interim, fixed-term or permanent recruitment offers the right solution. 

The role of HR in organisational change 

Whatever the reason for reform, restructure or transformation, it will almost always affect people. 

For HR teams, the challenge is often balancing day-to-day responsibilities with limited internal resource, restructuring activity and increased employee relations demand. 

Employees want clarity on what change means for them. Managers need support to lead their teams with confidence. Leadership teams need trusted advisors who can balance financial or service delivery pressures with employee experience, employment law considerations and organisational risk. 

Within the public sector, this can also involve formal consultation, trade union engagement, redeployment, job evaluation, equality considerations and changes to terms and conditions. All of this must happen while essential services continue to be delivered and organisations remain accountable to employees, elected members, regulators, service users and the wider public. 

An effective HR function helps organisations bring these priorities together by: 

• Translating business strategy into a clear people strategy. 
• Supporting leaders to communicate change effectively. 
• Maintaining employee engagement during periods of uncertainty. 
• Managing complex employee relations issues and consultation processes. 
• Planning future workforce requirements. 
• Supporting redeployment and the retention of critical skills. 
• Ensuring change programmes are implemented fairly and consistently. 
• Helping services maintain continuity throughout the transition. 

Rather than responding once decisions have already been made, high-performing HR teams are involved from the outset. This allows them to anticipate challenges, understand the workforce implications of proposed decisions and reduce the risk of delays or avoidable employee relations issues.  

Where public sector HR teams are under pressure 

Even experienced HR teams can come under significant pressure during organisational change. 

In many cases, the issue is not a lack of capability. It is the expectation that the existing team will manage a complex transformation programme alongside its usual workload. 

We are seeing pressure emerge in different ways across the public and not-for-profit sectors. 

Local authorities are preparing for devolution and local government reorganisation while continuing to manage wider workforce and budget challenges. 

Academy trusts are reviewing structures, central teams and shared-service arrangements, often while working within defined budgets and established pay frameworks. These projects can create demand for short-term HR professionals who can support consultation and employee relations activity without adding permanent headcount. 

Within the NHS and wider healthcare sector, organisations may be considering role redesign, redeployment or redundancy processes. HR teams must help leaders balance cost pressures with fairness, workforce retention, staff morale and service continuity. 

Housing associations may be dealing with mergers, regulatory change or service reviews, while universities and charities continue to face funding pressures and complex workforce decisions. 

Across all these settings, HR teams may need additional support in areas such as: 

• Employee relations and consultation. 
• Organisational design and development. 
• Workforce planning. 
• HR systems and data. 
• Policy, pay and reward. 
• Job evaluation. 
• Change communications. 
• Senior HR leadership. 
• Project and programme delivery. 

Reviewing these pressures early allows organisations to make more considered recruitment decisions rather than trying to secure urgent support once internal capacity has already been exceeded. 

The capabilities every HR team needs 

The role of HR continues to evolve, and so do the skills required to support complex workforce change. 

1. Strategic and organisational thinking

Modern HR professionals need a strong understanding of the wider organisation. Within the public sector, this means understanding service pressures, funding constraints, workforce needs, governance arrangements and shifting organisational priorities. 

HR professionals need to align people decisions with organisational priorities, balancing financial pressure, service delivery, employee engagement and long-term workforce capability. 

They also need the confidence to advise and, where necessary, challenge senior leaders. HR should not simply be brought in to implement decisions after they have been made. It should help shape those decisions by identifying their likely workforce impact, practical implications and potential risks. 

By taking a strategic approach, HR can help public sector organisations build the skills, structures and leadership capability they need, both now and in the future. 

2. Change management expertise

Public sector employers are increasingly looking for HR and organisational change specialists who can support restructures, redundancy processes and wider transformation programmes. 

Successful change does not happen by chance. It requires careful planning, clear communication and visible leadership. 

HR during organisational change plays a key role in helping organisations prepare for change, supporting leaders through difficult conversations, managing resistance and ensuring employees understand both the reasons for change and their role within it. 

In local government, for example, devolution and local government reorganisation can involve bringing together teams, services and organisational cultures. HR and organisational development professionals may need to support the design of new structures, map future workforce requirements and help leaders establish a shared culture and direction. 

In academy trusts, restructures and central team reviews can create a need for focused HR project support. Within the NHS, change may involve redundancy programmes, redeployment or redesigning existing roles while retaining critical workforce capability. 

When an organisation has the right HR resource in place, it can make the difference between a workforce that understands the direction of change and one that struggles to adapt. 

3. Employee relations and employment law knowledge

Restructures and transformation programmes often bring increased employee relations activity, from consultation processes and policy changes to grievance management and difficult conversations. 

Public sector organisations must also consider trade union relationships, collective consultation requirements, established pay and grading structures and the need for fair, transparent decision-making. 

Having experienced HR professionals who can navigate these situations confidently helps organisations reduce risk while maintaining fairness, consistency and trust. 

This work can be particularly demanding during large restructures or redundancy programmes. Even a highly experienced internal HR team may struggle to absorb the additional caseload alongside its existing responsibilities. 

Organisations therefore need to assess not only whether the relevant expertise exists internally, but whether those individuals have sufficient capacity to deliver the work properly. 

4. Workforce planning and talent strategy

One of the biggest challenges organisations face during a restructure, merger or service redesign is ensuring they have the right people in the right roles. 

HR teams are increasingly using workforce data and market insight to identify capability gaps, anticipate future skills requirements and develop recruitment and retention strategies that support long-term business goals. 

This is especially important when services, organisations or regional structures are changing. 

Local government reorganisation and devolution, for example, require employers to look beyond current structures. They need to understand which skills will be required in the future, where there may be duplication, which capabilities must be retained and where new leadership or specialist expertise will be needed. 

Similar questions arise when an academy trust centralises services, an NHS organisation redesigns teams, or a housing association reviews its operating model. 

These periods of transition also create an opportunity to think differently about workforce planning. It is not only about replacing roles. It is about building the skills, experience and leadership capability the organisation will need in the future, in line with its long-term goals and people strategy. 

5. Organisational development and cultural change

Creating a connected organisation requires more than structural change alone. 

When teams, departments or organisations come together, employees may have different ways of working, different expectations of leadership and different organisational identities. 

Organisational development specialists can help leaders understand these cultural differences and create practical plans for bringing people together. 

This is particularly important during mergers, local government reorganisation, shared-service arrangements and the growth or consolidation of academy trusts. 

Without attention to culture, a new organisational structure may exist on paper while teams continue to operate separately in practice. 

6. HR systems, data and people analytics

Reliable workforce information is essential during any major change programme. 

Leaders need accurate data about roles, skills, vacancies, turnover, absence, employee demographics and future workforce requirements. 

HR systems and people analytics professionals can help organisations understand their current workforce, model different scenarios and monitor the impact of change. 

This expertise is also important where organisations are bringing together different HR systems, employment records or reporting arrangements. 

Poor or incomplete data can slow decision-making and create additional risk. Reviewing systems and data capability should therefore form part of change planning rather than being treated as a separate technical exercise. 

Building HR capability during times of change 

In situations where internal resources are under pressure, organisations often benefit from strengthening their HR capability through additional expertise. 

This may involve bringing in interim HR professionals to support a transformation programme, appointing someone on a fixed-term basis to deliver a defined project or recruiting permanent specialists who can provide long-term strategic leadership. 

Investing in HR capability during periods of transition helps organisations manage immediate priorities while also putting them in a stronger position to respond to future challenges. 

However, organisations should avoid recruiting for “general HR support” without first defining what they actually need. 

Different challenges require different expertise. An employee relations specialist may be needed to support consultation processes and complex casework. An organisational development professional may be better placed to help align cultures, behaviours and ways of working. A workforce planning specialist can help identify future skills, critical roles and capability gaps. 

Being clear about the problem the appointment needs to solve makes it easier to identify the right person and provides candidates with a more compelling and realistic brief. 

Common mistakes organisations make when reviewing HR capacity 

One of the biggest mistakes employers make is waiting until change is already underway before reviewing HR capacity. By the time consultation is approaching, employee relations activity has increased or senior leaders need urgent advice, the organisation has less time and fewer options. 

Other common challenges include recruiting for “general HR support” when the real requirement is more specialist, underestimating the additional workload created by restructures or redundancy programmes, and allowing recruitment timescales to stretch beyond what is realistic for short-term assignments. 

Employers should be clear about the problem the appointment needs to solve. Whether they need employee relations expertise, organisational development support, workforce planning capability or senior HR leadership, a focused brief will help attract stronger candidates and lead to a better appointment. 

Why short-term HR support is becoming more common 

One trend we are seeing more regularly is demand for short-term HR support. 

This is particularly common where public sector organisations are dealing with restructures, consultation exercises, centralisation projects, redundancy programmes or changes to their operating models. 

In some cases, the organisation does not yet have approval for permanent headcount. In others, the work has a defined timeline or requires a specific skill that will not be needed indefinitely. 

Short-term support can also give internal HR leaders the space to focus on strategic change. For example, an additional HR Business Partner or employee relations specialist may keep business-as-usual work moving while senior members of the team lead a wider transformation programme. 

The challenge is that short-term roles still need strong candidates. 

Candidates with relevant public sector change experience are likely to have several options available to them. They will want a clear brief, realistic timelines and confidence that the organisation can make decisions quickly. 

A three- or six-month role can be attractive when it offers meaningful work, clear outcomes and the authority to make an impact. It becomes much harder to recruit when the scope is vague or the appointment process is longer than the contract itself. 

Interim, fixed-term or permanent HR support? 

Public sector employers often know they need additional HR resource but are less certain about the type of appointment that will provide the best solution. 

Interim HR support

Interim professionals can be particularly valuable where an organisation needs immediate capacity, senior expertise or experience of delivering a similar change programme. 

They can step in quickly, assess the situation and support leaders through a specific phase of change. 

This approach may suit urgent consultation work, senior HR leadership gaps, organisational design projects or situations where the organisation needs specialist expertise before determining its longer-term structure. 

Fixed-term HR support

Fixed-term appointments can work well when there is a defined programme, funding period or project timeline. 

This could include an HR system implementation, a restructure, a centralisation project or a programme of workforce transformation. 

A fixed-term contract can provide continuity throughout the project while recognising that the requirement may not continue once the work is complete. 

Permanent HR appointments

Permanent recruitment is appropriate when the organisation needs long-term stability, leadership and capability beyond the immediate change programme. 

This may include appointing an HR Director, Head of HR, senior HR Business Partner or specialist who can support the organisation through transition, strengthen the HR function and help shape its future people strategy. 

For some organisations, a blended approach will be the most effective solution. Interim or fixed-term professionals can provide immediate project capacity, while permanent appointments strengthen the HR function for the longer term. 

Looking beyond the immediate change programme 

One of the most common mistakes organisations make is treating transformation as a short-term project. 

In reality, transformation rarely ends once a restructure is complete or a new operating model is introduced. 

Organisations continue to evolve. Public policy changes, financial pressures remain, workforce expectations develop and new skills become essential. 

Change is an ongoing process. 

Building an effective HR team means developing a function that can respond to continuous change with confidence. That includes investing in leadership capability, strengthening employee relations expertise, embracing workforce planning and ensuring the organisation has access to specialist skills as priorities evolve. 

It also means learning from each programme. 

Organisations should consider which aspects of change placed the most pressure on the HR team, where additional expertise was required and whether temporary support revealed longer-term capability gaps. 

Public sector organisations with resilient, strategically minded HR teams are better placed to attract and retain talent, support their people through change and deliver sustainable services. 

Building an HR team that is ready for what comes next 

Public sector change is placing greater expectations on HR teams, from consultation and employee relations to workforce planning, organisational development and data-led decision-making. 

Any public sector organisation that knows significant change is coming should review HR capacity early. Leaders need to consider what the existing team can reasonably deliver, where specialist support may be required and whether interim, fixed-term or permanent recruitment provides the right solution. 

Whether you are preparing for local government reorganisation or devolution, redesigning NHS services, restructuring an academy trust, responding to a merger or leading a wider transformation programme, investing in the right HR talent will help ensure your organisation is ready for what comes next.
