Walter Foster on the Massachusetts Equal Pay Law

Walter Foster, a member Eckert Seamans' Labor and Employment Group and Boston office, discusses how the Massachusetts Equal Pay Law is making companies take a hard look at their compensation structure and compensate comparable work with comparable pay.



Walter Foster maintains an extensive practice in employment law, business litigation, municipal law, and pension law, providing counsel to both private and public sector employers on the legal and regulatory standards that govern the modern workplace. He has more than 30 years of trial and appellate experience, including business disputes, non-compete litigation, and employment-related disputes. Notably, Walter has handled numerous jury trials and public hearings involving claims of sexual harassment, disability, race, national origin, gender, age, sexual orientation, and religious discrimination before state and federal courts, Massachusetts Commission Against Discrimination, and Equal Employment Opportunity Commission. He has also appeared on several occasions before the Massachusetts Supreme Judicial Court, including a case concerning the constitutional right of a jury trial in discrimination law cases.

As part of his employment law practice, Walter conducts discrimination and workplace investigations, drafts workplace policies including data security breach policies, and provides advice concerning employment contracts, non-competition agreements, and wage and hour compliance issues. He handles class action wage and overtime disputes at both the state and federal level. In addition, he provides comprehensive consultation services and training sessions to assist business clients in designing policies that promote a professional work environment compliant with state and federal laws, as well as helping to reduce or prevent the incidence of disruptive employment-related claims. Together with Safety and Respect at Work, LLC, he co-hosts a yearly workplace investigation three-day training session valuable to human resource professionals and companies of every size and has completed the MCAD certified courses on investigations and training in the workplace. In addition, as part of a working team of lawyers at Eckert Seamans, Walter helps international businesses open and operate in the United States and abroad, and helps them navigate the complex regulatory and legal framework in today’s international economy. Walter helps guide expanding businesses as they grow into foreign markets and shepherds them through the initial legal hurdles to enter the United States markets.

Prior to entering private practice, he was an Assistant Attorney General in Massachusetts, defending numerous state agencies and departments in administrative law appeals. Walter has served as the Chief of the Massachusetts Bay Transportation Authority’s labor law unit. He has also served as a Special Assistant Attorney General. Walter has a working knowledge of the complex and organic state retirement statute Chapter 32 and drafted an opinion of the Attorney General concerning the applicability of specific retirement provisions under the state’s retirement statute to the judicial branch.
