• Develop and embed standardised ER toolkits, templates, guidance, and training to ensure consistency, compliance, and high-quality case handling.
• Provide functional (dotted-line) leadership to HR Business Partners on ER practice, setting expectations for quality, consistency, and timeliness.
• Coach and develop HR colleagues to strengthen capability, judgement, and confidence in managing complex and high-risk ER cases.
• Partner with senior leaders to advise on complex people matters, organisational change, restructures, and risk mitigation strategies.
• Support the end-to-end procurement and implementation of a new HRIS, working closely with the Manager of People Operations (dotted-line collaboration) to define requirements, support vendor selection, and embed effective processes.
• Contribute to the evaluation and selection of payroll solutions, including potential outsourced payroll provision, ensuring compliance, accuracy, and operational resilience.
• Embed “brilliant basics” across HR operations, including policy clarity, data integrity, process consistency, case tracking, and service standards.
• Strengthen people data reporting and ER trend analysis to enable data-driven decision-making and early risk identification.
• Build strong cross-functional relationships with Finance, IT, Procurement, and Legal to support successful transformation outcomes.

• Advanced ER expertise: Ability to manage and advise on complex, sensitive, and high-risk employee relations matters with sound judgement and commercial awareness.
• Strategic transformation capability: Skilled in diagnosing systemic issues and designing scalable, sustainable people processes and frameworks.
• Influencing at peer and senior level: Ability to provide constructive challenge and guidance at Head-of level and below.
• Coaching and capability building: Demonstrated ability to uplift professional standards and performance through structured development and mentoring.
• Systems and process orientation: Strong ability to translate business needs into HRIS requirements and improved operational workflows.
• Commercial and risk awareness: Balances legal, financial, reputational, and cultural considerations in decision-making.
