You check what you own, especially your bond fund (government bonds are safe, if it has anything else look closely) and your investments in financial firms (see if any of them have been buying up this bad debt). Company-run pension plans are usually scams (a financial institution sells them a bunch of expensive actively managed products not a few cheap index funds) but picking the best of a bad lot still has big returns and sometimes it just takes one or two employees to get them to add something much better to the list.
