Position Summary

The HR Manager serves as the senior HR practitioner and operational leader for approximately 1,200 employees across two locations: the Kansas City corporate and primary manufacturing facility and the Sedalia, Missouri location. Reporting directly to the VP of Human Resources, this role owns the day-to-day execution and strategic delivery of human resources across the full employee lifecycle — with particular depth in employee relations, legal compliance, complex investigations, and workforce management.

This is a working manager role with five direct reports based in Kansas City: an Assistant HR Manager, an HR Generalist, an HR Coordinator, and two front desk/reception staff. The HR Manager is accountable for the development and performance of this team while simultaneously functioning as the primary subject matter expert on complex HR matters for managers, supervisors, and site leadership across both locations. The scope and complexity of this role demands a seasoned HR professional who can operate both strategically and in the details.

TEAM STRUCTURE & DIRECT REPORTS

The HR Manager leads a team of five direct reports, all based at the Kansas City location:

• Assistant HR Manager — serves as the primary backup and secondary HR authority; supports ER matters, manages a defined employee population, and assumes the HR Manager’s responsibilities in their absence.
• HR Generalist — supports employee programs, HRIS data integrity, leave administration coordination, onboarding, and day-to-day employee support.
• HR Coordinator — manages administrative HR functions including personnel records, I-9 compliance, HR inbox triage, and onboarding logistics.
• Front Desk / Reception Staff (2, Kansas City) — first point of contact for employees and visitors at the Kansas City facility; support HR administrative functions as directed.
  
  

HR support for the Sedalia location is extended through the HR Manager and team on a remote basis, supplemented by regular on-site visits to the Sedalia facility approximately every other month (estimated 6 visits annually; day trips typical given the approximately 90-mile distance).

• Partners with legal counsel and the VP of Human Resources on matters that escalate to litigation, EEOC charges, or formal legal correspondence; prepares documentation, position statements, and chronologies as required.
• Manages workers’ compensation matters including initial reporting, coordination with the carrier, return-to-work planning, and ongoing communication with employees and supervisors throughout the process.
