Knowledge transfer should be baked into the day-to-day culture of work, not something desperately scrambled for during someone's last week. Those few companies with meaningful training and mentoring programs know this.
> The plant [...] has an apprentice program for millennials, but there’s a shortage of Generation X workers. “We’ve got a big gap in the middle, so we have to keep talented people in their 60s a little longer,”
Here we go again with the "shortage of workers". In one article it's tech workers. Here it's GenX workers. A "shortage" of a good is pretty meaningless if you don't mention the price you're offering to pay for that good. Unless they're saying they literally can't find qualified GenX workers at any price--That would be a real shortage. Otherwise, maybe you need to just offer a little more money to find skilled mid-career workers nowadays.
With so many people under-employed or out of work, it borders on insulting to claim there's a shortage of workers.
