  • Enroll new hires in medical, dental, vision, and other benefit plans within required enrollment windows
  • Coordinate new hire paperwork, systems access requests, and orientation logistics

Workers' Compensation

  • Manage workers' compensation claims from initial incident report through resolution, serving as the point of contact between employees, carriers, and management
  • Ensure timely, compliant reporting of workplace injuries in accordance with state and federal requirements
  • Track claims status, maintain accurate records, and support return-to-work coordination

Policy & Communications

  • Partner with the HR policy team to develop, update, and refine company policies and procedures
  • Roll out HR communications and policy updates company-wide, ensuring clarity and appropriate change management
  • Support managers and employees in understanding and applying HR policies consistently

HR Business Partnership

  • Serve as a trusted advisor to assigned business units/leaders on HR matters, including employee relations, performance management, and organizational needs
  • Partner with managers on employee relations issues, investigations, coaching, and corrective action processes, in coordination with HR leadership and legal as needed
  • Support performance management cycles, including goal-setting, reviews, and improvement plans
  • Provide guidance on compensation, promotions, and role changes in partnership with Compensation/Total Rewards
  • Analyze HR metrics and trends (turnover, engagement, headcount) to inform recommendations to business leaders
  • Support workforce planning, org design, and talent management initiatives
  • Assist with off-boarding processes, including exit interviews and separation compliance
  • Ensure compliance with federal, state, and local employment laws and regulations
  • Maintain accurate and confidential employee records in the HRIS
  • Support diversity, equity, and inclusion initiatives at the business unit level
  • Participate in cross-functional HR projects and continuous improvement initiatives
