A little known game companies play, and with your signed consent, is the 401K game.
I know too many who faithfully contributed their maximum %, only to lose the company match if the company closes within, say, the 5 year minimum for contributions, if that is what the agreement states. They end up with only the amount of their contribution and no interest on the money, either. Happened at DH's company. They could have invested same funds in a mutual fund of their own choosing and done better.
Another 401K scheme is that all your contributions, not to mention the company matches, are lost if you leave employment within a certain amount of time. Happened to SIL and I thought she was pretty savvy.
Read your 401K material closely, ask for clarification if you suspect the language is deliberately confusing you. Watch what you sign.
OK, Susie Orman, how do ya plan for that? That sets you years behind and with no wiggle room if you are nearing retirement with the volatile job market that exists now.
