So you guys didn't read the actual e-mail (why not, it's all over the internet) or the OPM memo/fact sheet?
It's not a buyout despite early headlines. It's an agreement that if you opt for a deferred resignation for the last day of the fiscal year you will be exempted from the return to in person work requirements.
That's it. Keep doing your job, keep getting paid, until the end of the fiscal year.
The only people likely to take the offer are those who were already planning to resign or were on the fence because they cannot or do not want to work in person. But again, they will still keep doing their jobs (in as much as they were before) remotely until the end of the fiscal year.
There's no VSIP/VERA/Buyout. That would actually get a LOT more people to leave and would actually shrink the government because billets that get VSIP/VERA are removed, they don't get to be filled by new people (the point being that the job is no longer necessary, which is why they are offered a bonus to vacate the job).
