Do you act like you are going to get RIF'd? The upside is you are mentally ready if you do get RIF'd. The downside is you caused yourself weeks of stress and worry if you end up not getting RIF'd. Like the saying says, "worrying does not change tomorrow, but ruins today".
Or do you act like you're going to be just fine? The upside of this is no stress and worry. The downside is that it hurts even more if it does happen.
What is your mental state during this time?
