My previous workplace was like this. It didn’t get to this point, I left before it got to the point of being told you’re not allowed to wfh under any circumstances, but I was very confused why I needed to go to the office, to do my IT job, helping people with their computers remotely. I go to the office, to work remotely. Which doesn’t make any sense at all.
What is special about the office that allows me to work better/faster/more effectively/whatever? Nobody could give me an answer. I can easily run the tools at home and work fine from there, but I’m not allowed.
My specialty is in network operations, if they want my work to 100% go through their equipment and firewalls and stuff, I can make that happen. With little effort, I can setup a system on a VLAN, and VPN that VLAN to work, blocking it from all other traffic apart from the VPN. It would be the only system on that VLAN (apart from the firewall/VPN device), ensuring no possibility of cross contamination between my equipment and theirs. They even had an openVPN host already configured, which they would only need to generate a connection file for, in order for me to get it working. I can then proxy 100% of my traffic through an office system and it would be identical to being present in the office, apart from me being physically there.
At home I have a dedicated room for my computer activities, where I can close the door and lock it if required, so I can remain undisturbed.
I made sure they understood all of this but they still wanted me in the office at least 4 days a week. I’m still not sure why.
I left that job, and my new job doesn’t even have a physical office, so I’m permanently working from home.
