Generally, an employer cannot discriminate between employees on the basis of sex, or on the basis of sex in combination with another protected status (disability, race, creed, color, sexual orientation, gender identity, gender expression, marital status, religion, age, national origin, or ancestry) by paying an employee of one sex a wage rate less than the rate paid to an employee of a different sex for substantially similar work, regardless of job title, based on a composite of skill; effort, which may include consideration of shift work; and responsibility.[1]
a) Affirmative Defenses: To justify a pay disparity, an employer can assert that it was based on a seniority system, merit system, system which measures earnings by quantity or quality of production, geographic location where the work is performed, travel if the travel is regular and necessary condition of the work performed and education training or experience to the extent that they are reasonably related to the work in question.[2]
b) Retaliation: Employers may not discriminate or retaliate against a prospective employee for failing to disclose his or her wage rate history, may not discharge, discriminate or retaliate against an employee for invoking the Equal Pay for Equal Work Act or assisting in the enforcement of the law, and may not discharge, discipline, discriminate against or interfere with an employee because that employee inquired about, disclosed, compared, or otherwise discussed his or her wage rate.[3]
