I think a little nudge is good but if they are not receptive to it, I don't bring it up again. Finance is very personal stuff and my some of friends/family get embarrassed/uncomfortable discussing that.
also I think it's important to not be completely out of touch since most people in my circle don't have enough money to have a safe savings/emergency stash, let alone invest into retirement. I don't want to piss people off or make them despair talking about FIRE if I know they don't have good income leftover to begin with. That's just been my experience with it, curious how you guys think about it.
Tons of companies have 'officially' pushed out RTO, mine included, but here in Bay Area it's still up to the agreement between direct managers and employees to keep WFH going. So my team still does WFH and other reasonable managers continue to do so for their teams as well. I hope that works out for your case too.
