The Leave Extension Request Letter is a crucial document used when an employee needs to extend their previously approved leave period. This formal communication is particularly relevant in the United States, where leave entitlements are governed by federal laws such as the Family and Medical Leave Act (FMLA) and the Americans with Disabilities Act (ADA), along with various state-specific regulations. The letter should be submitted before the current leave period expires and must include specific details about the original leave, the extension timeframe requested, and the reason for the extension. It may also reference or include supporting documentation, particularly for medical-related extensions. This document helps ensure compliance with legal requirements while maintaining clear communication between the employee and employer regarding extended absence arrangements.
