Overtime sheet in Excel

I am trying to create a rotating list of employees. Currently I have a list of employees in the Employees tab that will populate in order when the respective number is placed in C2 in the Employees tab. However, I am trying to see if there is an easier way of doing this. Previously I had a drop-down that allowed me to add more staff with the =Offset option, however they where not populating the remain staff in the other cells. I would like for the Staff Rotation in OT Sheet tab to auto fill so that if I pick Staff D in B31 Staff E will auto populate in B32 and so on. Or is the way I currently have it the best option. Thank you once again.
