The argument is self-evident: weekend penalty rates are out-of-kilter because in a modern, secular, 24/7 economy, Sunday has become just like any other day.

Here's one reason. Because, it turns out, the loudest, clearest proponents of this change take a different view about their own leisure time.

Indeed, these new-economy warriors guard their Saturdays and Sundays so jealously, they close their offices on the weekend to guarantee quality family time.
