It'd be easier if you had cpc #s to give and your staffing requirements for your day. I worked at a facility that had 11 cpc requirement for 100% and 6 cpcs for each day. There was usually 4 to 5 guaranteed 4 10 lines with it rotating through the week for RDOs. Facility hours was 645 to 915 and the 4 shifts the 4-10s could work was 1115-915, 10-8, 8-6, and 645 to 445. Usually had someone "paired" with the 4 10s who would essentially shadow their shift and double the closers and openers incase of a bang out. Mainly had to convince management that sick leave wouldn't potentially result in OT. I can see if I can get the MOUs the facility had if you want to look them over.
