Wow I didn’t think I would ever see anyone openly state in writing that it is too hard to fire people for being old. (Age discrimination against those 40 and older is against federal law. It’s also morally wrong. I would also personally argue that the age cutoff should be a lot lower, but that is directly relevant to this article).
Edit: ahh that makes sense. He likely meant it as “or just plain ol’ ‘you’re not doing a great job.’ “
