Some of us don't have permanent desks at work (not saying that is what is going on here), but there can be many reasons to 'pack up and bring home' work stuff.
That is what I did. I took the job as a knee-jerk reaction from losing projects because or covid as a freelancer. I think it has to do with the ISO security certification. It brings lots of little nuisances.
The ones that I've worked at still allowed you to keep your things in a locked drawer. I'm surprised to hear there are places that don't even allow that much.
In such companies it should be straightforward to request a particular keyboard for health reasons (risk of RSI). If you're lucky you can get exactly what you want, at worst it would be a Kinesis Advantage or Maltron.
Very common in Pharma/Life science as documents are highly controlled, also anything visible to an auditor is seen as a risk to be managed. Auditors if the want can ask to see inside drawers, cabinets etc
I got in the habit during the early days of RTO. I did start a second board, but (as is tradition) I upped the difficulty and it's now gathering dust on my bench.
For three years!?
Why not make another one and leave it at the office?
I lasted less than a week after buying a split, ergonomic keyboards before I bought a second for the office.
