Copied from @Z1zrPd2-qmi Your direct manager has no say in who gets laid off. It is typically decided by a senior VP or higher...often times someone that knows little or anything about you. It can be based on your direct group for example if your client group recently had work move to india. So they will look at a client group and determined at what level they no longer need, how many and then from there who costs the most ...maybe on a smaller scale if someone is incompetent.
They care more about Money than quality so if you are cheaper than someone else in the group you will stay before the other person unless you are so woefully bad it is obvious . .the best thing start s---ling really really bad....they may still keep you if you are significantly cheaper.
I couldn't have said it any better and I agree with everything that you said. So many of my peers have either left State Street or been outsourced. Not sure about increasing your chances of getting selected. You just need to update your resume and leave State Street on your own. Of course speaking to any attorney as suggested isn't a bad idea either.
