Iiiiiiiiiiiiineresting. This certainly aligns with my belief that the selectively continued officers' eligibility clause means Big Blue really doesn't want us passed-over folks around.
To me, it makes sense: If I've been here 15 years, they have to assume I'm staying until 20, ESPECIALLY if they've already offered selective continuation. If they can get out of paying me my six-figure salary for the next 4 years, and replace it with a 38.4% retirement (I'll have 16 years as of August), they come out ahead. In four years they'll save ~$90K/year, then about $10K every year after that as long as I continue to stink up the planet. Plus they get rid of a guy who's clearly no longer interested in any flavor of Kool-Aid they offer.
For me, it's an escape to go be an airline guy and get in on a lower seniority number, but with something to show for my 16 years. For BB, it's a chance to get rid of a dude who doesn't fit their paradigm, and is also kind of expensive to pay. And before anyone reminds me that the grass might only appear greener over there, understand this: I'm not interested in leaving because the grass is greener over there. I want to leave because the sh*t is chin high and rising over here.
