Just would like to start out by saying hello... I am new to the boards and I am looking for some assistance with this issue... thanks in advance... I know that this is well above my skill level and would be greatly appreciated.

I am trying to create a list that will rotate the seniority list in 3 different ways. Monday through Friday Mandatory Overtime starting from the bottom persons with the least amount of seniority. Voluntary Starting from the top persons with most seniority. all stating the facts of who is on deck in both directions and last person hit coming in early and staying over...

All revolving around a regular 8 hour shift. 4 hours early "AM" and 4 hours over "PM"
