Human Relations Manager Jobs in Rialto, CA (NOW HIRING)

Mission Linen Supply is seeking an experienced Employee Relations Manager to provide HR leadership and counsel across several locations. This role will drive key initiatives in performance management, organizational effectiveness, and employee communication.

This role requires hands-on experience working at a unionized employer. You must have direct, practical experience navigating a union workplace — responding to grievances, participating in collective bargaining and contract negotiations, and applying a collective bargaining agreement day to day. This is a required qualification, not a preferred one.

Why Mission Linen Supply

If you're looking for a stable industry with real influence over how employee relations and labor relations are handled across multiple sites — this role is built for that. Mission Linen Supply is a family-owned, privately held company and a leading provider of linen, uniform, and facility service products across five western states. Founded in 1930 and headquartered in Santa Barbara, CA, Mission has grown from a one-man operation into an industry leader, while remaining stable, essential, and steadily growing. Industrial laundry and linen services are a recession-resistant, essential industry — hospitals, hotels, and restaurants need clean linens and uniforms regardless of the economy. That means real, ongoing opportunities for career advancement, not a static org chart.

The Opportunity
