Firsty, let me make a bold statement: Everyone now is a remote worker or mobile worker. I'm basing this on a few assumptions: one, you actualy work from home or off-site or at some point outside of your organisation’s physical space, you answer emails, take calls, read presentations on the train,meet with others at different locations.
This means we are all, in some shape or form, a remote worker. As I said, there are of course those who are actual remote workers, most of the time based elsewhere, whether in a satellite office, at home, co-working spaces or just travelling on the road.
The below diagram gives some stats on Americans who reported working from home. And this is just working from home!
