This is a very good question. It's not exactly clear how to incentivize this among employers. I think workers recognize that they need to upskill to work with whatever the new technology is in their domain, but I feel that employers and HR don't make enough space for this, or they don't see the value.
What's a lot more common generally is that sometimes it's easier to separate with a worker who's been with you for a while and has a higher wage, when you can hire somebody out of college for much cheaper, who's just entering the workforce and is already prepared to work with new technology. Exactly how to do this re-skilling on the fly for folks who are already in the middle of their careers is an open question.
