Do I have to keep time records for all my employees?

No, not for all employees, but, yes, for all nonexempt employees, even salaried nonexempt employees.  These time records need to accurately track all required meal breaks, rest periods, available sick time, overtime, etc., and you must retain them for three years.  Inaccurate or incomplete time records can result in severe penalties and payment of back wages.  Because of this, we have developed a proprietary Timesheet in fillable PDF format with electronic signatures for both the employee and manager/supervisor that comports with California timekeeping requirements and is available for a flat fee for unlimited use in perpetuity.
