• Coaching & Manager Capability – Support and develop line managers through coaching and leadership training, embedding consistent, fair and confident people practices.
• Employee Relations Leadership – Own complex ER cases – absence, disciplinary, grievance and performance – guiding managers with clarity, fairness and legal awareness.
• Policy, Process & Compliance – Champion consistent policy application, refine HR documentation and ensure alignment with legislation and union agreements.
• Workforce Planning & Talent Support – Involved in succession planning, recruitment activity and wider people planning to build stability and future capability.
• Projects, Culture & Improvement – Lead key HR initiatives including engagement programmes, ED&I activity, policy improvements and absence‑reduction projects, contributing to a strong culture.

Qualifications & Experience

• Proven HR generalist with solid experience and confidence to influence stakeholders at all levels.
• Experience in a unionised manufacturing environment is highly advantageous.
• Strong knowledge of employment law and HR policy.
• Strong communication skills across diverse teams.

• Curious, proactive and ready to bring fresh ideas.
