These steps guide managers on how to terminate an employee who quits, retires, or abandons their job. HR requires at least 3 business days' notice to process a final paycheck. According to CA labor law, if an employee resigns with at least 72 hours' notice, their final pay is due on their last day of work. If the employee resigns without any notice, the final pay must be provided within 72 hours of their resignation. In the case of involuntary termination, the final pay is due on the term date.
