Southern California. Western regional supplement. But i believe article 40 in the master supersedes the others
You get all three, since article 40 does not directly contradict my jc37 articles on overtime (for example) then they both apply. Overtime after 8 hours, overtime after 40 hours, overtime outside of the regularly scheduled workweek, overtime after a 5th punch, overtime on a holiday.
I believe that my local is in agreement to offer double time on a 7th punch in one workweek but I cannot find explicit language.
I would find your BA for at least 1.5X pay, working Sunday through Saturday means you definitely worked 40 straight time hours prior to friday/saturday.
