Left "Mega-Corp" like 15 years ago , before getting my last job at "Mega-City".
Got a letter , advising that I will be eligible to start collecting retirement benefits on next birthday , with detailed instructions on how and when to start the application process.
Kind of surprising , I left them 15 years ago . The business unit I worked at doesn't even exist anymore. Hat tip to the corp. HR folks.
Going to draw from both "Mega-Corp" and Mega-City" plans, together a fraction of last paid work, but enough to meet basic living expenses.
The non-cola "mega-corp" monthly retirement check is not much , but will cover the retiree cost portion of medical insurance.
