The Family and Medical Leave Act (FMLA) allows eligible employees to take up to 12 weeks of unpaid leave per year for specific family and medical reasons, ensuring job security and health insurance coverage during the leave. Employees must meet eligibility criteria, and employers must adhere to notice requirements and can require medical certification. FMLA includes provisions for military caregiver leave and allows for intermittent leave while prohibiting any loss of employment benefits due to the leave.
