  • Support monthly payroll by providing accurate starter, leaver, absence and contractual change information.
  • Help improve HR processes, templates and ways of working.
  • Support employee wellbeing, engagement and inclusion initiatives.
  • Work with internal teams to communicate HR and people updates effectively.
About You
You will need:
  • Previous generalist HR experience within the UK.
  • Practical experience managing Employee Relations cases.
  • Good knowledge of UK employment law and HR best practice.
  • Confidence advising and supporting managers.
  • Strong communication and relationship-building skills.
  • Excellent organisation and attention to detail.
  • The ability to manage confidential and sensitive information professionally.
  • Good HR administration and record-keeping skills.
  • A practical, approachable and solutions-focused style.
