"While the date on which actual accrual of paid sick time begins is measured from July 1, 2015, the time period for when an employee may use accrued paid sick time is measured by the actual date of employment.... While the law references '24 hours or three days' as the amount of paid sick leave that must be provided on an annual basis, the law also defines a 'paid sick day' as time that is 'compensated at the same wage as the employee normally earns during regular work hours.' For employers whose employees work on an alternative workweek schedule, such as a four-day per week, 10-hour per day schedule, a 'paid sick day' might actually be 10 hours of wages for the employee, or 30 hours."
