Btw, this reply will also be to those who take time to read it:
I guess it really is dark for those whose tenure status were "Career", then transferred to another agency for a new position. From what I remember, you earn "Career" status after your one-year probation period is over...or maybe it's three years. I once resigned from the federal government after 9 years, then came back in the federal government 8 months later under a different agency, as an intern, with a different position. When I came back in, my tenure status on my SF-50 still read "Career", like it read when I left. Although they hired me, and the rest of the new interns (who were much younger than me) under a one-year probationary period, I don't think the "Probationary" status really applied to me...I could be wrong. But I carried it as though it did regardless. Then only a few months after I started, they relocated me to a different building further away, still under the same agency. These were older employees, much closer to retirement. In fact, I replaced one, who was kinda forced out because of a medical condition, although he was 52, and had a heart attack before. He was an older White man, who they kept suggesting should retire, and move South...but he didn't want to. I guess he finally did.
To tie this all in, when I came back in the federal government under that different agency, I think I was eventually relocated to that different building, because my tenure on my SF-50 read "Career", and they couldn't get rid of me easily, like they could the rest of the interns. So I may have endured all that panicking for nothing. But then again, I did have to wait for my top security clearance to clear...an SCI at that. FF to today, anybody who transferred to a new agency, then got fired, after they had at least 3 years of federal service, should have a chance to win their job back, especially if their new SF-50 reads "Career", under their tenure status. I don't think they're allowed to change that status. But I never worked in OPM, so I'm not sure.
Personally, there's no way I would transfer as a "Career" status federal employee, to another federal agency under a "Probationary" status. But then again, I guess I had done something much riskier when I resigned from the federal government that time, to work in the private sector as an IT professional...so they could lay me off three months later for no reason. But I had just graduated from college with an IT degree, and tried to get some IT experience, and caught the first plane smoking. However, I dIdn't know it was that toxic out there in the office job environment. I thought I had arrived, but found out later I had much more security as a federal guard. Anyway, if the federal government brought me back in under "Career" status, after I had actually resigned, then it seems like anybody who only transferred to another agency, would keep their "Career" status, and wouldn't be officially placed back on a "Probationary" status. Then again, I never worked in OPM. So I don't know if they were required to keep me under a "Career" status when I came back in, or not. But it's sure worth looking in to, for people who've been terminated recently, after they transferred to another agency under a "Probationary" status, even though they already had over 3 years of federal service. I'd began by checking my SF-50. Anyway, after what I experienced, I would never voluntarily go from a federal "Career" employee to a federal "Probationary" employee, even if I was transferring to an agency paying more money, with a better career.
