So one of my close colleagues (who is also a friend I have worked with at companies prior) informed me in private that he was being made redundant and was asked to leave immediately with full notice payment. He was told that in accepting this he would not be able to tell anyone else about it at all. He informed me in confidence as we are semi-close that this was the first of a number of redundancies within my department of 10(ish).
I am 90% sure I am safe as I am a dev team lead, but I was planning to leave at some point in the next few months, and I was thinking I could save someone's redundancy by volunteering. The only issue with this is that I would have to disclose that I know the company is going to be making redundancies, meaning I put my colleague/friend in legal danger.
I feel like there isn't anything I can do here unless someone in senior management makes it obvious this is happening.
