Once in a while you get shown the light, in the strangest of places, if you look at it right
My uncle spent years preaching to me about the need to be loyal to a company. I never drank the Kool-Aid. He spent 21 years working for an investment banking company in their IT department. 4 years before he was set to retire with a full pension, etc. his company was acquired by a larger bank. He lost everything except his 401k. He then spent the next 12 years working to get his time back so he’d be able to retire. He died 2 years ago and the company sent a bouquet of flowers.
THE COMPANY DOESN’T CARE ABOUT YOU!!
So the way he explained it to me was that essentially when the company was purchased all your accruals were reset and the pension was tied to years of service, which he hadn’t reached yet, then with the merger you were essentially a new employee. There was also a lot tied to retirement plans linked to corporate stocks that were basically useless after they merged. Either way, beyond working for the same company forever, his eggs were (mostly) in one basket.
