We are looking for an Employee Relations Manager to join our People team in a hybrid role that combines employee relations (50%) with a strong focus on complex terminations and grievance handling and HR operations (50%). This role is ideal for someone who is equally comfortable managing structured HR processes and navigating sensitive, high-stakes employee situations with sound judgment, empathy, and discretion. You will act as a trusted advisor to managers and leadership on employee relations matters, while also ensuring the day-to-day HR operations run smoothly, accurately, and in compliance with local labour law.

What You Will Be Doing

• Employee Relations (50%)
  • Lead and manage complex termination cases end-to-end - from case assessment and documentation, through manager/HR team coaching, to final execution - ensuring legal compliance and minimizing organizational risk.
  • Serve as the primary point of contact for employee grievances, conducting fair, thorough, and confidential investigations.
  • Advise managers and leadership on performance management, disciplinary processes, and difficult conversations.
  • Build and maintain strong working relationships with stakeholders across departments.
  • Draft and review sensitive documentation: performance improvement plans (PIPs), warning letters, termination letters, settlement agreements.
  • Identify patterns or recurring issues in employee relations cases and proactively recommend policy or process improvements.
  • Ensure all ER activity is handled with appropriate confidentiality, empathy, and fairness toward all parties involved.
  • Maintain thorough, well-organized case documentation to support consistency, defensibility, and institutional knowledge.
• HR Operations (50%)
  • Own and maintain core HR processes: onboarding/offboarding, contract administration, employee data management, and HRIS accuracy.
  • Ensure compliance with local labour law, internal policies, and audit requirements across all HR documentation.
  • Manage and continuously improve HR workflows, templates, and standard operating procedures (SOPs).
  • Prepare and maintain HR reporting and metrics (e.g., headcount, turnover, termination) for leadership review.
  • Support payroll-adjacent processes.
  • Serve as a point of contact for employee questions on policies, contracts.
  • Partner with Legal and Payroll on process alignment, documentation standards, and risk mitigation.

About You

• 5+ years of experience in HR, with a mix of HR operations and employee relations experience.
• Demonstrated experience managing complex or contested terminations and grievance/investigation processes.

• Solid working knowledge of international labour law of multiple regions and different types of engagement (employment, B2B) and HR compliance requirements.
• Strong stakeholder management skills; able to influence and advise managers and senior leadership.
• Excellent judgment and discretion when handling sensitive and confidential information.
• Strong written communication skills - comfortable drafting formal HR documentation (letters, agreements, case summaries).

• Ability to balance empathy for employees with the need to protect the business and act decisively.

Nice to Have
