There hasn't been performance criteria used in years ! Just ask hundreds of us who have been riffed before yourself who had great reviews, were considered the go-to persons for advice/questions/problem solving. They aren't sitting down with managers or sr managers ahead of time and having a pow-wow about who stays or who goes. There is some secret algorithm being run....- that looks at how much you make, how many years service, and what severance they would have to pay get someone off the payroll. In others words, how can they maximize the cost savings based on the group. In the case of the CS orgs being decimated in this case, this wouldnt apply because it sounds like entire orgs are going to be sent offshore to vendors. DO NOT BELIEVE FOR ONE MOMENT YOU DID ANYTHING WRONG. THIS IS THE WAY OF ALL CORPORATIONS NOW...THEY SUCK.
An older post by @1tha+1mNJBOrF that should be revisited now. We all need a reminder of this from time to time.
