What is HR?

HR is the department within an organisation responsible for managing everything related to its workforce. At its core, HR focuses on supporting employees, maintaining healthy workplace relationships and ensuring compliance with employment law. HR also plays a vital role in fostering engagement, wellbeing and productivity.

The responsibilities of HR can be grouped into key areas:

• Recruitment and onboarding: attracting, hiring and integrating new talent into the organisation
• Employee relations and engagement: managing workplace culture, addressing concerns and boosting morale
• Learning and development: supporting training, career progression and professional growth
• Performance management: monitoring goals, appraisals and feedback systems
• Compensation and benefits: managing salaries, pensions, leave and other employee perks
• Compliance and policies: ensuring adherence to UK employment law, health and safety regulations and company policies

In smaller UK businesses, HR duties may fall to a single person or a small team, whereas larger organisations often have specialised HR professionals for each function.

The breadth of HR means it touches nearly every aspect of an employee’s working life, from recruitment through to exit, making it an essential component of a successful organisation. Understanding what HR does can help business leaders optimise workforce management and support long-term growth.

HR basics: what does human resources do?

The term human resources covers a wide range of responsibilities and is often one of the most vital parts of any organisation. HR exists to support employees, ensure compliance with legislation and maintain smooth day-to-day operations.

Below are the 11 key duties and responsibilities typically carried out by HR professionals or departments in workplaces:

1. Manage recruitment and exits

HR oversees both hiring and employee departures. On the recruitment side, they define roles, set selection criteria, evaluate CVs, conduct interviews, perform background checks and coordinate onboarding paperwork.

For departures, HR manages exit processes, including notice periods, returning company equipment and revoking system access, all while maintaining professionalism and compliance with UK employment law.

2. Oversee performance reviews and promotions

HR supports managers in evaluating staff performance, coordinating regular review cycles and recommending promotions or pay increases. HR staff also ensure appraisal processes are fair, consistent and documented in line with UK employment practices. This includes providing guidance on appraisal criteria, salary benchmarking and development opportunities.

3. Enforce workplace safety and legal compliance

HR helps maintain a safe and compliant workplace in accordance with the Health and Safety at Work Act 1974 and HSE guidelines.

Responsibilities include:

• conducting health and safety training and risk assessments,
• managing accident and incident reporting,
• investigating harassment, bullying, or discrimination complaints,
• and ensuring policies meet employment law requirements, including working hours, holiday entitlements and maternity/paternity leave.

By taking ownership of these areas, HR protects employees and mitigates legal risk.

4. Handle payroll, compensation and benefits

If you don’t have a dedicated finance team, then HR typically manages all aspects of employee pay and benefits. Responsibilities include:

• calculating salaries, deductions and tax contributions (PAYE, National Insurance, etc.),
• managing expense reimbursements and bonus payments,
• administering pensions and statutory benefits,
• processing pay increases and promotions,
• and designing and managing benefits such as flexible working, private health schemes, wellbeing programmes and reward initiatives.

Offering attractive benefits can be just as important as competitive pay in attracting and retaining top talent.

5. Create staffing plans and policies

HR ensures the organisation has the right people in the right roles at the right time. Key duties include:

• developing workforce plans to meet business growth or seasonal demands,
• drafting and updating company policies to align with UK employment law, including disciplinary procedures, holiday entitlement,and flexible working policies,
• and communicating policies clearly to staff to maintain consistency and support corporate culture.

6. Foster positive relationships

HR nurtures productive relationships across the organisation, like mediating conflicts between employees or between staff and management, promoting teamwork and collaboration, and encouraging a respectful and inclusive workplace culture.

7. Follow through with disciplinary action

HR handles complaints and enforces company standards, for example:

• investigating breaches of conduct, including harassment or misconduct,
• conducting disciplinary hearings in line with UK ACAS guidelines,
• and ensuring fairness and transparency to maintain trust and legal compliance.

8. Track employee satisfaction

HR monitors engagement and morale to maintain a motivated workforce. This often involves:

• conducting surveys and analysing feedback,
• implementing career development pathways,
• offering vocational training, mentoring and recognition programmes,
• and supporting initiatives that enhance employee experience and retention.

9. Training and development

HR designs and delivers training to equip staff with the necessary skills. This begins with onboarding and role-specific training for new hires. HR also provides leadership training for internal promotions, alongside continuous learning programmes and upskilling opportunities.

10. Promote health and wellbeing

HR supports both physical and mental wellbeing, for example:

• access to counselling, employee assistance programmes or occupational health,
• flexible and hybrid working arrangements,
• and wellbeing initiatives, such as mindfulness sessions, ergonomic assessments and stress-management workshops.

11. Maintain employee records

HR ensures accurate record-keeping for both operational and legal purposes. This includes securely storing sensitive data regarding payroll, leave, benefits and performance while maintaining all legally required records such as contracts and statutory leave entitlements. The department must also guarantee strict compliance with GDPR and established data retention guidelines to protect employee privacy.

Understanding why HR is essential

While small business leaders may handle HR duties themselves initially, most growing companies benefit from a dedicated HR professional or team. Here are key scenarios when focusing on HR becomes essential.

Your firm is scaling

If your business is expanding, HR must be front and centre. An HR team helps identify skill gaps, manages recruitment processes and ensures new hires integrate smoothly. They also track employee performance, implement development programmes and maintain consistency in policies and procedures—all vital elements for sustaining growth.

Regulation or legislation is changing

UK employment law evolves regularly, covering areas like minimum wage, flexible working rights, maternity/paternity leave, and health and safety requirements under the Health and Safety at Work Act. Failing to comply can result in fines or legal action. HR professionals monitor these changes, update policies, and keep the business compliant, so leadership can focus on strategy.

Staff morale is low

Low employee engagement can harm productivity and increase turnover. HR supports workforce wellbeing through initiatives such as employee assistance programmes, flexible working arrangements, recognition schemes and clear career development paths. By addressing concerns early, HR helps cultivate a motivated and resilient workforce.

Current HR structures are overwhelmed

Even small teams have HR responsibilities, but as the organisation grows, these duties multiply. Without a dedicated HR team, tasks can fall through the cracks, affecting compliance, payroll and staff satisfaction. Investing in HR expertise ensures all responsibilities are handled efficiently, freeing other employees to focus on their core roles.

What basic skills do you need to work in HR?

Working in HR requires a blend of interpersonal, organisational and analytical skills. HR professionals must manage day-to-day employee needs while ensuring compliance with employment law and supporting business objectives.

Here are five essential skills every HR professional should develop:

1. Communication

HR professionals need excellent verbal and written communication skills. They conduct interviews, lead training sessions, deliver presentations and facilitate conflict resolution. Clear communication ensures employees understand policies, managers can implement procedures effectively and workplace issues are addressed promptly and professionally.

2. Decision-making

HR roles involve critical decision-making, from selecting candidates and structuring teams to managing redundancy processes. Strong decision-making ensures fairness, compliance with employment law and alignment with organisational goals. Documenting decisions also protects the company in legal or regulatory reviews.

3. Empathy

Empathy allows HR professionals to understand employees’ perspectives during sensitive conversations, such as performance reviews, grievance handling or wellbeing discussions. This can include supporting staff through flexible working requests, parental leave or mental health challenges.

4. Financial savvy

HR teams often manage payroll, benefits and compensation programmes. Strong financial literacy ensures budgets are adhered to and that employee rewards stay competitive and sustainable. This includes planning pension contributions, bonus schemes and salary benchmarking in line with market standards.

5. Multitasking and organisation

HR roles are varied and fast-paced. HR pros must prioritise workloads, manage multiple projects simultaneously and remain calm under pressure. Effective organisation ensures compliance, smooth operations and a positive employee experience.
