All that was offered was a "deferred resignation plan" There is no "severance package"
The offer is for federal employees that wish to resign:
"If you choose not to continue in your current role in the federal workforce, we thank you for your service to your country and you will be provided with a dignified, fair departure from the federal government utilizing a deferred resignation program. This program begins effective January 28 and is available to all federal employees until February 6. If you resign under this program, you will retain all pay and benefits regardless of your daily workload and will be exempted from all applicable in-person work requirements until September 30, 2025 (or earlier if you choose to accelerate your resignation for any reason). "
