Does anyone know how Starbucks calculates overtime pay in the US? Sometimes I've gotten overtime pay without working more than 8 hours in a shift - I think this is because I worked more than 8 hours within a 24-hour "workday." But what time does the 24-hour period begin each day? (CA state law says a workday is a consecutive 24-hour period beginning at the same time each calendar day, but it may begin at any time of day.) I'm curious because I'm scheduled to close and then work at 6:30am the day after, for 8 hours. If the 24-hour period starts anew at 4:30am or something, I still wouldn't get overtime for that.
