About This Role

As an Employee Relations Advisor on a contract basis, you will be the go-to expert for managing complex ER cases—from disciplinaries to investigations—across the UK and Ireland. Your work will directly shape a fair and compliant workplace, influencing how managers handle sensitive issues and supporting organizational change. This role is pivotal in maintaining employee trust and legal integrity.

💡 A Day in the Life

Your day might start by reviewing a new disciplinary investigation report, then advising a manager on a complex grievance case over a call. Mid-morning, you could draft a settlement agreement for a restructure situation, followed by a stakeholder meeting to discuss ER trends. Afternoon might involve coaching a HRBP on a tricky absence management case and updating case logs.

  • Don't downplay the contract nature; show enthusiasm for temporary assignments and ability to deliver quickly without long onboarding.
  • Avoid focusing only on case handling without mentioning stakeholder management or change initiatives—these are key requirements.
