None, I have colleagues that received that and that led me to believe companies needed to do that. Not quite sure why they would request a guy to go mindlessly to an office where there is nobody of his management line and no colleague.

To be fair, I worked for a company previously that didn't provide facilities for remote working as a general rule (i.e. access VPN that existed for sales), but I still had 1 colleague in my team that was working from home full time (i.e. using the VPN).

So I guess it must be random.
