Just going off my purely anecdotal experience with being fired as an underperformer, most companies don't do well in the improvement/mentoring aspect with underperformers like myself. I think part of the problem is that many of these calls for improvement or churn come from HR and they're handled by folks who aren't trained in mentoring and skill training. I think if there was more emphasis on helping supervisors actually learn how to mentor and train to improve underperformers to get them up to the same level as the rest of their team then there would be fewer articles like this. But it seems like it's easier to throw people away than to help improve them.
