I am in a organization that runs 24 hrs a day, and the day in split into 3 8-hour shifts. Some of the employees work from the central office. But I also have a few dozen telecommuters. The system I have supports only 1/3 of the workforce without suffering from performance degradations. Everyone is given a specific Shift. They don’t change shifts. Some of the telecommuters are working “after hours” so that they can get there work done. The employees that work in the company itself can’t work extra hours because I only have the needed amount of workstations necessary to run according to each shift. Each employee has to leave there workstation at the end of there shift so the next shift can log on. I need to find a way so that I can prevent the telecommuters from logging on beyond the regular shift. How do I do that?
