I suggest that federal agencies start saving by swithcing from 5 day 8 hours workweek to 4 day 10 hours. I am speaking of those working in the office environment, not in the field.
This is simple measure and can be implemented right away. This measure will save huge amount of money spent on energy cost, utilities and transportation. Another benefit is that it is more eco friendly- less emission into the athmosphere reduction of traffic etc.
Last but not least the employees will have longer weekends so they will be more productive starting their week well rested. I know some private companies already saving in this manner. Why not federal government?
