I imagine those paid hourly (wages, contractors, construction, accountants, lawyers, etc.) track their work time very closely and have very precise definitions for not work, paid work and unpaid work. It’s not everyone but it should be a significant portion of the work force and I imagine some kind of conclusion can be drawn from it.
