I concur but there are a lot of companies that equate butts in seats with productivity. Plenty of employers still have the mentality that they have purchased 40 hours (or more) from you. What employers should think is that they are purchasing productivity, not hours.
But productivity is a harder thing to measure-far harder than just tracking hours.
It is harder to measure productivity, but surely even implementing a measuring system that was less than perfect would still be more beneficial to them.
