Pros
It could have been an interesting transition.
Cons
I was with SAIC for nearly 29 years when my project went to Leidos as part of the "gentleman's agreement" that split the company. As far as I was concerned the split was handled very poorly with very little communication about what it meant. The upshot was that if I had remained with Leidos I would have kept my service time, but what was not told was that if a Leidos employee went back to SAIC that they would lose it; those who were with SAIC, however, and moved to Leidos would keep theirs. Anyway, my project imploded and I was forced to find new work. Given that there was a partial government shutdown, a corporate HR that was being stood up, it was just a mess. I went back to SAIC after 2.5 weeks as a Leidos employee and guess what: I lost my service time (which meant that nearly 30 years of service DID NOT COUNT for anything and I had to start all over again as a BRAND NEW employee!!!
