PA SB237

Amends Pennsylvania's Equal Pay Law to prohibit sex-based wage discrimination for "comparable work" (substantially similar skill, effort, and responsibility) rather than only "equal work," and removes the limitation to within a single establishment

Expands the definition of "wages" to include all earnings regardless of calculation method, plus fringe benefits, wage supplements, and other compensation

Shifts burden to employers to demonstrate wage differentials are based on bona fide seniority, merit, production/sales systems, or other job-related factors consistent with business necessity that account for the entire pay gap

Authorizes the Attorney General to bring actions on behalf of employees to collect unpaid wages, damages, equitable relief, and attorney fees without paying filing fees

Extends the statute of limitations from 2 years to 3 years for willful violations, with each discriminatory paycheck constituting a new violation
