Crew Rotation Spreadsheet

[agunsmoke]

I'm new to this forum so Hello!!!

I have a need for a crew rotation spreadsheet.

I'm trying to figure out how to organize a work month per calendar year that involves working a 24/7 schedule.

Goals
Maximum hours per person per week = 70 hours.
Shifts are 0600 - 1800 and 1800-0600.
We have 15 men crews.
Need to give each person one week off per month.

Probably haven't given all of the details but if anyone has a spreadsheet that I could look at I would greatly appreciate it.

Thanks
