Entire finance departments can work from home, my company is 100% remote, its a fintech company that handles and processes sensitive stuff all day.
Never impeded by regulation or data safety concerns, in fact, I think this company has better security practices than others I've worked for in the past to be quite honest.
There is an illusion that security requires an office. Most of it comes down to 'can you trust X person' vs any locality stuff.
I'm unaware of any meaningful difference in practice when it comes to the work stream though.
That said, I'm no lawyer nor an expert on the differences between the US (where I reside) and the rest of the world, in terms of specific data laws and handling procedures
I do manual labor. My manager (a very nice guy) must show up on location. After we talk about things I message him and repeat the very things we've talked about so that I have a written record of things.
They have him drive around the country for useless chit chat. If I ask him why stuff isn't done it is always this same excuse. He has to go to meetings where the goal pretty much is to write my whatsapp message on a piece of paper and for other people to hear themselves talk. I sometimes jokingly ask him how it went. The usual response is PFFF, a 5 hour drive for nothing. He manages both the day and the night shifts which adds to the joke.
I think we need to send in the environmentalists so that people can stop burning my gasoline, eroding my roads, killing the birds, stinking up my city, taking my parking spots and wearing out their car.
I propose a special daily commute tax, a flat fee for the first 20 km with extras per additional km and a multiplier for each hour shorter than 8 before the return trip. Lets also do an office tax per square meter.
Certainly for bigger deals they come onsite for the final stages of the sales process, but most interaction is handled remotely and they aren't in an office.
