Employers are advised to maintain employee information across three separate folders (digital or hard copy):

• Folder 1 (General Employee) — employment application, job description, reviews, discipline, and training certifications
• Folder 2 (Confidential / Medical) — medical clearances, investigation notes and reports, PWFA notes, and ADA interactive process logs
• Folder 3 (I-9 / Immigration) — I-9 forms and verification documents, stored separately from the other two folders
