Instead of allowing Managers to hold back telecommuting (and they are) it needs to be expanded. New language needs to come down from the department level saying to use it as much as possible and enforce it. The President and previous President has signed off on this as has Congress but it's not getting down to the worker bees.
If your position is the type where a large percentage is done on the computer or phone there is no good reason you cannot telecommute 2 or more days a week. That way space, electricity, water etc. would be less in the offices. With all of the rental properties (I am in one) that could be a huge savings. Also think of the gasoline drop? Gas is high as it is and the country is looking for ways to save everywhere it can so why not here? Last but not least it could only help the traffic issues we have around DC.
