"[A]ll new employees hired on or after January 1, 2015, must be given the notice at the time of hire. As to employees who were hired prior to January 1, 2015, the notice must be given within seven days of the date that the sick plan is implemented. Since the deadline for implementation is July 1, 2015, the notice must be given to existing employees by no later than July 8, 2015. The agency has taken the position that even if the employer's existing written paid leave policy or sick leave policy already complies with the new law and will not be changed as a result of the law the employer must still distribute the notice."
