I am a committeeman for a UAW chrysler facility in California. Please let me pose a scenario to all of you. I would appreciate any feedback.
FACTS:
-California labor law defines a "WORKDAY" as: "Any consecutive 24 hour period commencing at the same time each calendar day"

-Workers on the Friday 2nd shift work from 1:00 p.m. until 11:30p.m.

-Workers on second shift must come in at either 6:00a.m. or 8:00a.m. If they would like Saturday Overtime. (sat voluntary ot shift is 6:00a.m.-2:00p.m.)

-Workers work more than 12 hours in a 24 hour cycle and are not paid double time after 12 hours in any 24 hour cycle.

-Company (DaimlerChrysler) has no policy defining their work day.

-Because Saturday OT is voluntary, do we forgo any rights to double time, even though we may work more than 12 hours in a 24 cycle?

-Does the UAW Chrysler contract in any way supercede stated California state law?
I WOULD APPRECIATE ANY HELPFUL ADVICE...THANK YOU!!

Of course it doesn't. However, I didn't see in your post what the employer defines as the beginning of the workweek and that is what determines overtime, not when a particular shift starts or how many hours are worked consecutively. Each 24 hour period stands alone. The employer MUST define the workweek.

this is the workweek defined according to the dcx uaw national agreement.
-The regularly scheduled workweek starts at 12:01 a.m. and ends 168 hours thereafter.

Also....Is California labor code defining ot pay for after 12 hours in same 24 hour cycle nullified because we have a collective bargaining agreement? It states that in the labor code....but strange definition.

Appreciate any help!

I'm assuming by "24-hour cycle", you mean from 12:01 a.m. to Midnight?

Yes, your collective bargaining agreement can waive doubletime.
