Humans are very sensitive to being ostracized, and modern layoffs in aggregate are at least partially (~20%) intended and communicated as being ways to get rid of 'low performers', so we know that even when we get laidoff simply due to not making a cut line on a spreadsheet we still think it may be due to our own performance and also that others may think that as well.
vibe layoffs are bad practice due to fundamental attribution error (line managers don't necessarily have any idea who their low performers are even if they think they do) and ultimately expose the company to discrimination lawsuits if hr doesn't enforce a fair and consistent selection criteria
