Ask HN: What's the answer to “Back to the office to train younger poeople”?

One of the major arguments I have seen to get back into the office is to help train younger / newer employees - this article for example: https://www.standard.co.uk/news/politics/back-to-office-duty-older-workers-young-people-gillian-keegan-wfh-b948933.html

What is the answer to this for remote workers? What can we do so we dont have to commute and spend all our money on coffee?
