I live in CA and think my double time hours are being counted wrong. I already know that the CA labor law states any hours worked "in a day" over 8hrs is paid as OT and any worked over 12hrs is DT (double-time). The issue is this: I come in and work my 8hr shift 6:00am-2:30pm. Then, I come back at 8:00pm in the same day and work until 1:00pm the next afternoon. That means I worked 8hrs on my first shift, then came back after only 5.5hrs of a break and worked the next 16hrs straight.
Even though this is now a new "day" it is my understanding that since I started the second 16hr shift in the same day that I worked the first 8hr shift (and with only 5.5hrs break between), the count should continue from the prior shift. So, that first 8hrs in the AM is regular pay, then 8pm-midnight is OT pay, then everything after midnight would be DT pay.
My work is currently paying the first 8hrs regular, then when I come back that evening they are starting me over again with the next 8hrs regular then 4hrs OT then 4hrs DT. I don't think this is correct but the only labor law info I can find specifies the hours worked "in a day" but never comes across the situation of a person's shift(s) crossing over into a "new day".
Does anyone have any specific resources that I can use or find mentioning the cross over into a new day or anything close to this?
