Reading these posts, I am surprised at the number of posters who hate people like themselves, who work for a living and want the best situation for themselves as possible.
At my own state university, we not only proved that work efficiency did not change, but also sick days and other time off requested fell by 33 percent. Power usage in the main computing center dropped by 40 percent. Employees were happy and the work was getting done (a lot of it is working on virtualized systems). No braving traffic (nor using more gas, despite the university being "green".)
But they want everyone back by September, sitting in their office at a computer, when doing the same thing at home was no different. You are just staring at different walls. But the truth is, the state wanted a bargaining chip for union negotiations next year. Bargaining chips. So much for valuing their employees.
