I'm not certain about the exact intricacies of the Schedule A hiring authority so I may be corrected by someone later - but my understanding is that this would not be possible to be rehired under the same hiring authority. People have joked about doing both a Schedule A and an Intermittent Consultant[0], which would allow you to do 4 years (2x2) - as we've just hit our 1st birthday, no one has tried it yet!

[0] There are some slight differences in how pay, retirement, and some other benefits are distributed, so they are mostly but not entirely interchangeable.

Do you get 2 years worth of pension? ie 2 40ths (or whatever the accrual rate is )

Pensions have a 3 year cliff - but you're only allowed to work for 2 as a schedule A and you don't accrue years as an IC so one can conclude with very high confidence that I will not have a pension :D.

Ah sneaky if a highly unfair to the people taking a paycut to work for their country.

I'm not an expert (by any stretch of the imagination) on federal hiring policy, but my appointment is 2 years, with the opportunity to extend another 2 years. No clue what happens after that.
