Hello John T F,
Thanks for participating in our Ask the Experts event today. As to your question, whether or not your other pension plans will reduce your pensions due to outside income depends on the specific plan documents of each plan that was approved by the IRS. I know that some governments pensions do and some don't because of the way their governing body created the plan. Yet, there is no hard and fast rule and private pension plans may or may not have the same provisions.
I wish I could be of more help, but the best way to figure that out is to contact your pension plan administrator or look for information on their website.
