Staff should definitely have some availability management. Maybe a tie in to the meeting scheduler? if there was a tick box ‘remove me from allocations when i am not available on this calendar’. I don’t know if meeting schedules allow you to block out days, but we would be happy if it include 365 integration and excluded days marked as non working days.
We have also often sought the ability to have weighted distributions. But I understand how the current rotation system works, it is simple but does not fit well with weighted distribution. I would like to think that we can maybe rotate between teams, and be member of multiple teams too. i.e. the rotation goes between team a and team b - at this point, it is 50/50 between teams. The rotator needs to remember that the allocation was to team a or b etc. then within team a, there can be 2 people who rotate as per normal but team b can be 3 people. Using this method, I would be able to have person a, b in Team a, then person a, b, c in team b. person c would in theory recieve 20% share, and person a and B would receive 40% each.
