This bill aims to enhance transparency, fairness, and protections for diplomatic personnel facing reductions in force (RIFs) within several foreign affairs agencies. It establishes new requirements for covered agencies, including the Department of State and USAID, when conducting significant RIFs affecting more than 50 employees within a six-month period. Specifically, agencies must provide Congress with a detailed explanation and justification for such RIFs at least 20 days prior to employee notification, assessing impacts on mission and U.S. diplomatic presence. The bill also standardizes Foreign Service RIF procedures, mandating a worldwide competitive area and prioritizing performance , tenure, language capabilities, and military preference in retention decisions. Furthermore, it requires a minimum 60-day advance notice for all RIFs and grants the Foreign Service Grievances Board authority to adjudicate RIF grievances, similar to the Merit Systems Protection Board. Additionally, the legislation extends the review period for the Foreign Affairs Manual from five to eight years and mandates congressional notice, consultation, and briefing before any changes to the manual are implemented. These provisions collectively seek to ensure greater oversight and safeguard the interests of the diplomatic workforce during organizational restructuring.
