“That graph pretty clearly shows a majority working in offices.”
That may very well be by looking at face value of the graph I found and posted. However I would have to see a detailed breakdown of the two upper categories of the graph.
For example “Professional and Management” would also include those thousands of field managers and supervisors who do not work in an office.
Also in “Service and Sales” the same would apply to that of the thousands of field service and sales personnel not working in an office.
Easily outweighed by millions of office drones...
