Is overtime counted for the days work or the week?

Federal labor law says that anything over 40 hours in one work week is overtime.

However, this only applies to time actually worked. So its very common to see paychecks with 48 hours of straight time if there is a paid holiday during the week or if an employee uses paid vacation time one day but works extra hours another day.

For example if Monday is a paid holiday and you get 8 hours of pay but the day off, then you work 4 x 10 hour shifts Tue-Friday you would get 40 hours of straight time for the 40 hours you actually worked, and 8 hours of straight time for the paid holiday, creating a 48 hour check. Most pay stubs would show the regular wage and holiday pay on separate lines, but not necessarily. Federal laws don't force the employer to pay OT for going over 8 hours in one day, only for going over 40 in the week.

Then there's the issue of California's laws which require OT for anything over 8 hours in one day.

But the federal law is enough that you should never see more than 40 hours of straight time unless the excess was from paid time off such as holiday or vacation pay.

In California anything over 8 hours a day or 40 hours a week is overtime.

That's overtime buddy, you cannot have more than 40 hours in one week paid at the same wages.

pls see the CA wage and hour commission's definition of overtime. i assume it is online

Federal law is anything over 40 hours is overtime. Some states and some local laws require overtime for anything over 8 hours in a single day.

Check with your local (un)employment office and they will be able to tell you the rule for where you live.

In California anything over 8 hours in a day is overtime and anything over 40 hours in a week is overtime.
