Not a huge impact. My agency and position (as have most other government agencies) have been deemed eligible for Voluntary Early Retirement Authority (VERA) BUT only if you take Elon's Fork in the Road offer. For my wife (same job I have) and I, the VERA is the most important aspect of the whole deal. Under that, you can retire with full benefits immediately (i.e. start receiving a pension, keep your health insurance). So for our agency, the VERA is authorized until the end of September so by sticking around until then, we'll get that time credited to service length and still accumulate leave while (in theory) still get paid. We would have gladly stayed on working until September but that option wasn't given. Return to Office wasn't an issue for us - we work full time from home and there wasn't much chance of us getting called back into the office due to space constraints (Agency employs 14000 people and we have room for 1300).
I'm hearing rumors at work that my position is going to be eliminated and I would have been demoted if I had chosen to stuck around, so I thought it was worth the risk taking the offer. Never expected my career to end this way but we'll be ok either way. I look at others going through the same thing and feel terrible about what he's doing to the Federal workforce. If we were 20 years out rom retirement, we'd pretty much be screwed.
