The Massachusetts equal pay law requires equal pay for comparable work, based on gender.[1] The law defines “comparable work” as work that requires substantially similar skill, effort, and responsibility, and is performed under similar working conditions.
a. Affirmative Defenses: To justify a pay disparity, an employer can assert that the disparity is based on a seniority system (except that time spent on leave due to pregnancy or protected parental, family and medical leave does not reduce seniority); a merit system; a system based on quantity or quality of production, sales, or revenue; geographic location where the job is performed; education, training, or experience if relevant to the job; or travel.[2]
b. Retaliation: An employer cannot retaliate against an employee for opposing a practice made unlawful under the equal pay act; making a complaint or instituting a proceeding under the equal pay act; or testifying, assisting, or participating in an investigation or proceeding under the equal pay act.[3] Retaliation is punishable by a fine of not more than $100.[4]
