This Practice Note describes the scope of permissible discovery employers can obtain from plaintiffs in employment discrimination lawsuits brought 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 stemming from an employer's discovery requests, including requests for and objections to social media content, electronic communications, medical records and psychotherapy notes, tax records, other lawsuits, and personal diaries. This Note addresses federal law but is also useful for handling discovery disputes under state or local anti-discrimination laws.
