I think you're getting "office" confused with "warehouse" and "laboratory".

People who work in ‘labs’, ‘warehouses’, and ‘manufacturing lines’ may also work in ‘offices’ throughout the day. For many engineers these spaces aren’t in isolation.

The vast majority of people who just work in an office, don't necessarily need to be in that specific office to do it.
