It really depends on who it's being offered to - if it is literally EVERYONE you need to evaluate it on a case-to-case, but if it's a small targeted group, you probably should take it.

Also if you're a manager you should be able to make it pretty clear.

A lowly line manager is not going to have any actual visibility into the VP-level machinations that decide the size and scope of layoffs.

But if they have half a clue they'll still be able to figure out which way the wind is blowing.
