WFH, it's a religion for some people. I personally absolutely must have my in-person work, but I understand the desires.
And that is an option too.
Not parent but presumably they mean WFH.
Hot desks?
A reservation system? I work for a remote optional company and employees can reserve desks ahead of time and/or you can get an assigned seat if you come in daily.
This is assigned hot desk which is better than just hot desk + reservation, which doesn't guarantee teams sit together.
Extreme pair programming but with 4 people instead of 2.
