SEVERANCE PACKAGE .... ? HAHAHAHA They ended those over two years ago. The only way you get one now is to HAVE something on them... If you are UP there in salary you can expect PIPS, write ups, notes to file, STRESSSSSSS, with the planned out come being you quitting or termination. Then they will oppose you getting Unemployment Insurance (they have lost nearly everyone of these cases that I am familiar with). On the positive side, most of the HR operatives are incompetent beer guzzling morons (the good folk left for greener pastures). So if you are clever, document things well, you may still get a deal at the end.
Key signs to look for to know you are targeted:
You are at or near the top of your pay scale.
You have at least 8 years with the company.
They start to rotate threats based on different metrics for YOU and always focusing on the worst one with no regard to the others. It becomes a near daily refocus if you start to improve on yesterdays, and OH this is IMPORTANT... Your THREAT metric may have no relationship to the companies published metric objectives. It's ALL about YOU and how to pressure YOU and make YOU look bad.
