I’ll try to get back this thread back on topic.
I believe any pension increase is decided by the pension board and is based on the financial strength of the individual pension. CS might be different because UPS took over the pension for UPS employees.
Bottom line, the amount paid into the pension is in the contract, not how much they can afford to pay out.
As far as when you decide to retire, that is completely a personal decision. You have more money by staying longer, but less stress mentally and physically when you retire. It is nice to still be young enough to enjoy the free time.
Just sharing an opinion, not trying to criticize or anything.
