Established in 1997, Kaiser Permanente and the Coalition of Kaiser Permanente Unions and the Alliance of Healthcare Unions have maintained a Labor Management Partnership. Their LMP is guided by a Founding Agreement that lays out core principles, structures and commitments. A 2021 Alliance National Agreement renewed both parties’ commitment to working in partnership. The Kaiser Labor Management Partnership is regarded as a national model for businesses and unions interested in establishing their own cooperative partnerships. A case study of the partnership’s early years offers useful insights for business and labor alike.
