Unlike many states, California has a law requiring that your employer provide your final paycheck on your last day of work, not the next regular payday. Final pay must include all accrued and unused vacation. If you resign without providing your employer at least 72 hours' notice, your final pay is due within 72 hours of your resignation.
If your employer violates this rule, you are entitled to a waiting time penalty. This waiting time penalty is an amount equal to your daily rate of pay for each day the wages remain unpaid, up to a maximum of 30 calendar days.
