Losing your biggest donor tends to complicate things. For the World Health Organization, it means preparing for one of the most dramatic workforce reductions in its recent history—a nearly 22% drop in headcount by mid-2026.
The cuts come as the WHO restructures following the United States' decision to exit the agency earlier this year. When your top financial backer walks away, you don't just tighten your belt—you redesign the entire operation.
The Trump administration formally withdrew from the organization in January, triggering swift adjustments across global programs and internal leadership. Washington historically contributed about 18% of WHO's total funding, making it the largest financial supporter by a considerable margin. That's not the kind of gap you fill with a bake sale.
According to internal projections prepared for member states and reported by Reuters, the WHO expects to shed 2,371 positions between January 2025 and June 2026. That would bring total staff down to just over 7,000 employees.
A WHO spokesperson confirmed the scope of the cuts, though noted that the final percentage depends on whether some vacant positions eventually get filled. Earlier estimates had indicated hundreds of departures, but this represents the first comprehensive picture of the anticipated reductions across the organization's global workforce.
Director-General Tedros Adhanom Ghebreyesus described the past year as one of the WHO's most challenging periods in a message viewed by Reuters, as the agency navigated both realignment and severe budget constraints.
Budget documents shared with member nations reveal a $1.06 billion funding gap for the 2026-2027 program budget—nearly a quarter of what the organization needs to operate. That shortfall is actually smaller than an earlier estimate of $1.7 billion, thanks partly to a reduced overall budget and an ongoing fundraising campaign.
The WHO also expects around $1.1 billion in additional funding through agreements still being negotiated. According to the spokesperson, the share of unfunded budget requirements is lower compared to previous periods, helped by higher mandatory contributions from member states stepping up after the U.S. departure.
It's a dramatic reshuffling for an organization that sits at the center of global health coordination. Whether the leaner WHO can maintain its operational effectiveness with significantly fewer resources remains the open question.
