I left XOM quite a while back - my advice is just go for it and don't look back, XOM wasn't for me and if you're not a certain type of person, there's no reason to force the fit for yourself into its culture.
I still have my pension tied up in the xom savings plan and it's a PAIN to manage (i.e. when you need to update info / change addresses) and just want to take a lump sum now. It's a paltry sum of money, so I don't really care about any discounting math at this point, the freedom from having to update my address is worth it.
Is there anyway to request a lump sum option?
