It’s not voluntary. It’s people communicating and doing each other a favor that works for everyone. It’s not far fetched that a VP and a distinguished engineer would have a meeting at least occasionally.

Just stating a lot of people are jumping to a conclusion without any facts.

Look at it this way.

VP: I have to come up with a list of people to let go. It’s a large amount and you have worked across many teams maybe you have some insight on some teams that we should look at first.

DE: … gives some advice. You know I was planning on leaving soon and maybe this is a good time to leave. I can help you hit your quota and you can give me a decent severance package.

VP: I hate to see you go but would be glad to help you out.

I have had almost this exact conversation.
