The philanthropy started by Bill and Melinda French Gates will shutter in 2045 and has plans to make a record $9 billion in donations this year while remaining primarily focused on health care and disease research.

While some were able to be assigned to other teams, the organization needed more research-heavy expertise to match the new mission, so some had to be laid off. They received a 60-day notice period and will get a severance package with 16 weeks of base pay, health insurance, and a $10,000 stipend to
