New York City Sick and Safe Leave: How do we calculate time?

Q:  When an employer implementing a paid sick leave policy to comply with the New York City Sick and Safe Leave law chooses to use the option of the “Front-Load” method (paid five days on the first of each year), what is the process for new hires during the year? Can the employer use the Front-Load method for all employees who have completed one year of employment and at the same time use the “Cumulative” method for new hires during the year? Or does the new hire receive five days' credit as of their date of hire?" – Kenneth, New York
