Good point...
So far however the emplyment of ShiftLogic for whatever reason has failed to provide ANY improvements for the operational staff or the management. It has provided an enormous amount of grief, and has cost unspecified THOUSANDS in the process.
As to the non-use of preferences, could this be something to do with the fact that if you put everybody's preferences into ShiftLogic it will crash? How so? There aren't enough ATCOs/ ATSAs, and it cannot cope with the conflicts generated? Just a thought.
