FYI this isn’t a term Americans know. I was super confused when I moved to the UK and kept hearing it mostly because people being made redundant weren’t technically ‘being made redundant’, if anything they were already made redundant (or just no longer needed for some other reason, or no longer affordable) and were now suffering the consequences. Idk, weird phrase, I’m going to go look up the etymology now. To be fair I suppose ‘laid off’ is pretty weird too
