IBM is very clever. Most people on this site think they are receiving "severance pay". IBM never ever uses that term, for good reason.
If you are RA'd and elect to file for unemployment, be very careful when asked if you received severance pay. You have NOT received severance from IBM, from IBM's perspective you have received a predetermined liquidated damage as a legal settlement. IBM will make you sign a release agreeing not to sue them even if you were the victim of age or race discrimination. Therefore you have entered into a contract with IBM to accept the payment and given up your valuable right to sue, in exchange for that payment, which is considered a liquidated damage. Nothing you will receive from IBM will categorize that settlement payment as "severance" so you should not call it that. If you mistakenly categorize the payment as severance you are delaying when you are actually eligible for unemployment compensation checks. Why, because the state unemployment office will look at the payment amount YOU called severance (but IBM did not) as an extension of your employment and therefore you are not eligible until that amount runs out. During that period you must meet the states' various requirements to receive unemployment. Most States include requirements like being able and willing to work and actively seeking employment.
