First thing to realize is that your 1st Line Supervisor or 2nd Line AM was just as blind-sided as you were. And they know full well that the fewer Indians there are, the fewer Chiefs there will be. I say this so you don't go ballistic on people who are as powerless as you feel.
So, you've been told you are on the sh--can list. What to do?
Job number 1- find another job.
While you still have company paid Internet access, start cranking out resumes and linking to every job site you can Google. While you still have access to Vendors, call all of those Nortel and Fujitsu and Cisco sales reps and let them know you are freeing up in 8 weeks. Call your customers and your BZ Accounts - they might just love to have a liaison with former Telco contacts.
Boss asks you about the TPS report - sling some c-ap together so you can't be accused of willful negligence and fling that turd into his Inbox.
Once you have been told your date of execution, your ONLY goal is to make it out alive and move on - you owe these people nothing.
