Attorney Trish Murphy has more than two decades of experience in workplace investigations, employment law, and labor relations. Since she began her career in labor and employment law in 1996, she has developed a pragmatic, results-driven approach to her practice, which is focused on independent investigations and management-side labor and employment law services in Seattle and across Washington State.

A seasoned workplace investigator, Trish devotes the majority of her practice to conducting independent investigations of a diverse range of claims including discrimination, sexual harassment, hostile work environment, retaliation, misconduct, ethics violations, improper governmental action, and bullying. She has performed more than 200 workplace investigations, many involving highly charged situations with complex facts and sensitive allegations. Trish’s investigative experience has spanned a varied array of parties and witnesses, such as executive leadership, unionized employees, public officials, students, tenured faculty, attorneys, and law enforcement personnel. She is an Association of Workplace Investigators Certificate Holder (AWI-CH) and a certified Title IX investigator (ATIXA).

Trish counsels and represents employers on a wide spectrum of employment law issues to help foster high-performing workplaces. Employers rely on her for practical guidance in such matters as employee handbooks, wage and hour issues, family and medical leave, and compliance with laws prohibiting discrimination, harassment, and retaliation.

She provides strategic labor relations representation and advice, from collective bargaining and labor arbitration to unfair labor practice and representation proceedings. Trish’s expertise includes over a decade of experience serving as chief spokesperson in labor negotiations, including bargaining with law enforcement and firefighter unions.

She also has served as a Contributing Editor for the American Bar Association’s Bloomberg BNA labor law treatise, The Developing Labor Law, since 2015.
