Desperation in incompetent management can do that.
You make it sound like age discrimination is a good thing. I hope that wasn’t your intended point. A lot of the reason older people are retiring is because they don’t want to deal with the incompetence and laziness of the newer generation. Those of us still sticking around often do it out of a sense of duty, to help bring the younger ones up to speed. Running us of simply because we don’t know the latest social media fad is a mistake.
