I assume you mean pension. If so, no you can not lose your pension. You can retire immediately. Keep in mind that your pension may be reduced for age if you are under age 65. All of the permutations are listed in the summary plan description which can be downloaded from the Ford benefits site. At least as of now, you can get severance and then collect pension. I believe this is outlined in the SIRP which you can find on Life@Ford easily enough.
I will be 55 with over 15 years of service in May and am very much considering bailing then. I won't collect my pension until 62. At least in my case, there is no difference between collecting at 62 and 65 and only a very modest reduction at 61. I would run the estimates on the pension tool on the Ford benefits site for yourself if you haven't done so already. The only thing giving me pause is healthcare. I've done some estimating on healthcare.gov, it is a bit frightening but I'm in good financial shape and I believe I'm good even paying on my own. Inflation is the wild card. If I do bail or get forced out, I may do some part time work for some income. Maybe you will see me at Home Depot stocking shelves one day. If I get caught up in the involuntary before I hit 55, then things change drastically for the worse.
