Sorry, I must not be communicating the issue clearly. I will try once more and then I will shut up.
I have no doubt that your pensions have been reliable to date. Probably that has been the case for the vast majority of public pension funds. No politician wants the bad press that comes from cutting retirees' pensions. So those cuts will only happen with the fund runs out of money or is so close to running out that the problems can no longer be denied.
The situation is kind of like Taleb's Turkey:

So IMO the fund needs a critical look so you can assess what risk you may have. Best would be if you have a CPA who can examine it for you. If you know an Accounting teacher, he or she may be a good first stop because they probably have the same financial interest as you do.
Please understand I am not making any predictions about
your pension fund, but public employees' pensions are in general very underfunded and hence at some risk. Hopefully yours is the golden case where there is no risk.
