A. Unfortunately, the answer is yes, thanks to a recent provision that is tucked into the Federal Spending Bill and approved by the Congress - this is unprecedented and could have very bad ramifications down the road for people who are counting on pension plans for their retirements.
You can search "critical status notices" at DOL.gov, where you can find if your pension plan is on the critical status list, which means the plan is endangered and underfunded, and could face a cut of benefits down the road.
If you are near or already at your retirement, it's time to create your own pension - annuity that could pay you as long as you live.
