You can't count on management to tell you anything regarding these RIFs, at least in IT. Those decisions were outsourced and done at a macro level, and approved at a group CIO level. VPs and below were caught completely off guard when their departments were decimated, and they were left to pick up the pieces. And there is no sign yet that it will stop.
The handwriting is on the wall, read it and make your decision as to what is best for you. But if you stay, do it as a decision not because of inertia.
