I don't understand what is so hard for the ELT to have a voluntary sign up of people who wants to resign. There are a couple of people that would love to sign up. It's not that hard, first get rid of PIP people, then people who voluntary signed up for LR, then what ever is left then do involuntary LRs.
I know what some people are going to say. Why don't you put your 2 week notice? Well, its because you don't get a severance package, you would want to try out your luck first before resigning. Now, I have to resign without a package.
