I'm new here, although I've read a few posts that searches have brought me to. I received a card in the mail the other day stating that I am now eligible for the teamster 401k. I asked a friend who has worked at UPS for a few years about it. He told me he doesn't use it because there is no matching and that I could just change my contributions at the upsers site once I have a year under my belt and UPS matches. He said he uses etrade to manage his 401k. I signed up, but haven't made any contributions yet. Is this something I should go ahead and do? Is this UPS's 401k or something supplemental? Figured I'd ask here, because getting answers at work is like pulling teeth.
