Quiet quitting is just middle management’s manipulative language for people doing their jobs adequately but then not putting in a bunch of unpaid extra effort. When there is no incentive to go above and beyond, why should anyone? It is the job of management to create those incentives, but if they are unwilling to pay for that, complaining about people’s work ethic to try to guilt them into doing unpaid work is their next strategy. It isn’t very effective.
