48-96 shift schedule

I am curious if anyone has, or, is currently utilizing the 48-96 shift schedule? It has been brought up for discussion within our department. We are currently working three 24 hour shifts with a day off in between, after the third day we have four days off. I am having a hard time believing the concept of the "increased productivity" quoted in studies that have been provided by proponents of the 48-96 schedule. I have tried to envision working another 24 hours after working the previous 24 and I am ready to go home and catch some zzz's.

How does this work out for the single parents? I think it would be difficult at best to obtain a sitter for a 24 hour shift, yet alone a 48 hour shift. Seems crazy to me just to justify having 4 consecutive days off.

How do the spouses/significant others feel about this type of schedule? How does it impact overtime staffing, sporting event standbys, and sick leave usage? Do you rotate personnel off medic units for the next 24 hour shift? What about keeping up with departmental training, inspections and other activities? If a crew was busy the previous day (call wise) how do you accomodate that for the next 24 hour duty day?

Due to the Division Chiefs work load how do you manage their schedule?

Your input is greatly appreciated,
