The global public health agency disclosed plans to cut its staff by almost a fourth – totaling more than 2,000 jobs – before mid-2026.
This decision comes after the United States, formerly the agency's biggest donor, withdrew financial support earlier this period.
The US government was contributing about 18% of the organization's overall funding, causing a substantial budgetary gap.
Based on organizational projections, the workforce will decrease from 9,401 positions in early 2025 to around 7,030 by June 2026.
The reduction of 2,371 positions includes staff reductions, retirements, and natural attrition.

This amount marks an improvement from a prior estimated gap of $1.7bn noted in spring.
These budget projections exclude a further 1.1 billion dollars in potential funding from current discussions with various donors.

This restructuring process is now nearing its completion, paving the way for the organization to progress with a renewed structure.
