I have heard of two instances of folks that their managers have told them, they are definitely NOT a candidate for layoffs. In other words, they already put together the list of who is a YES and a NO, just waiting to wrap up the numbers of the voluntary to see how deep they go on the list. These folks have been told they are safe.
If you thought you had a tight relationship with your manager and they haven’t given you the wink-wink, you are safe....be worried.
