Prior to establishing her professional neutral practice, Ms. Mayne had 30 years of collective bargaining experience as chief labor negotiator on the management and labor sides of the table. Renée Mayne saw that unresolved conflicts and disputes adversely affected organizations and their employees, and she dedicated a major portion of her career to resolving labor and employment disputes.  

Renée Mayne worked as a union advocate from 1986 to 1995, and a management advocate from 1995 to 2016. Ms. Mayne served as the General Manager for a tri-county labor union in California, and in public sector executive leadership positions for labor relations, employee relations, and human resources. She resolved grievances, complaints, and labor disputes through negotiation, mediation, factfinding, and formal hearing decisions.
