This Practice Note describes the scope of permissible discovery plaintiffs can obtain from defendants in employment discrimination lawsuits under statutes like Title VII of the Civil Rights Act of 1964 (Title VII), the Americans with Disabilities Act (ADA), the Age Discrimination in Employment Act (ADEA), and more. It provides an overview of the most commonly disputed discovery issues between employers and employees in plaintiffs' discovery requests, such as requests for and objections to other complaints of discrimination against the employer, personnel files, employee demographics, and company financial data. This Note addresses federal law but is also useful for handling discovery disputes under state or local anti-discrimination laws.
