OP, you're definitely bitter. IF you were "genuinely were FAMILY", you wouldn't be "bragging" about bing able to "get each one of them fired for the intimate things we've shared and that I know about them". Sounds like they could probably get you in trouble too.
I've seen no evidence of the leadership team (at all levels) encouraging "the shunning" of the LR'd. Even when I got on a manager's bad side after a skip level, when I was LR'd and another guy gave his 2-weeks notice the day the 2 of us were notified that we were being LR'd, they gave all 3 of us a going-away party. I'm sure I was invited because it would have been awkward to have a party for the other LR'd guy and the guy who was quitting and excluding me, but hey, they had it and everyone showed up for free food.
And to the other person, I am homeless now. Cancer, disabled spouse, massive damage to home from a freak natural disaster. I had plenty of savings. I was not a fool so knock off that line of BS. I planned for contingencies.
So having cancer, a disabled spouse, and having massive damage to your home from a freak natural disaster is Cisco's fault? You're not the only person who's been LR'd from Cisco with a disabled spouse. Join the club. I'm sorry that you lost everything, but don't blame Cisco for it. You said you "planned for contingencies", so I can only assume you had insurance on your home and that it would have paid for the massive damages.
Try getting laid off when the "dot com" bubble burst in the early 2000's, have a non-working disabled spouse, live & work in the telecom corridor in the D/FW metro area, and have Delta announce that they're no longer going to have DFW as one of the hubs and cut 100's of flights into & out of DFW on a daily basis. I not only had to leave the area to find work, I had to sell my home at a substantial loss because people weren't moving into the area to buy homes. But I'm not on some layoff site whining about that company letting me go, especially when they cut just a few of us to get the company's numbers below 50 so they could close the entire office 6 months later w/o having to comply with the WARN requirements. They let me go such that my employment/severance ended on Dec 29th because they paid their 401(k) matching annually to all employees on Dec 31st instead of matching payday-to-payday. That was a layoff decision with malicious intent to save money. The severance package was a measly 2 weeks plus 2 weeks for agreeing not to sue and they reminded me of my 2-yr agreement of non-compete stating I couldn't go to work for their customers and/or competitors which was virtually every technical employer in the area.
I've been able to find employment three times since turning 50. The first was a FTE role, but I ended up not being a good fit for the company and quit as soon as my new-hire commitment was complete so that I could keep the sign-on bonus. The next one was a contractor role which eventually turned into a FTE conversion. While age certainly makes it harder to find jobs, it's not a blacklist. I think it's harder than you think to hide the chip on your shoulder.
