I'm curious to see what other changes come about in this new sometimes-remote world.
These days, most professional employees get a set amount of vacation time, lets say 20 days. In the previous system, if you wanted to fly halfway around the world to visit family or what-have-you, you might use half of those vacation days in one go. Now, if you're only expected to be in the office 1 day per week ("Meeting Monday"), you could take that same trip and use just 2 days of vacation, assuming you're working, or at least a making a passable semblance of working during the rest of that trip. Heck, you could take almost half of the Meeting Mondays for a year if you work the rest of the time.
In some sense, that's no problem. One of the big points of remote work is that it doesn't matter where you are, as long as you get your work done. But the reality is, those occasional in-person days seem to be very important for really connecting with teammates. If Nomad Ned seems to always be missing Meeting Monday but I can rely on Local Larry to be there, I may be much happier and feel more connected with Larry, even if they both take the same number of vacation days per year.
Between geopay, tax rules, wanting employees to be close enough to an office for in-person meetings or emergencies, etc, I think employers are going to become much more invasive in terms of tracking the locations of their employees going forward.
