Strange. It might be a cultural difference.

I value outputs.

To worry about how work is done if it is done well is micro-management.

Some people do want to pay money to have employees that look busy. I knew someone (in America it has to be said) who lived on a road where one person would constantly be getting gardening done just to show that they could afford it. It was constant re-work and pointless, which just showed off how much money they had. Maybe there is an element of that at work.

Security guards and secretaries are a similar phenomenon. They're not really needed, so god forbid they were to study for evening class while at work.
