N.Y. Workers' Comp. Law § 203-B
Any eligible employee of a covered employer who takes leave under this article shall be entitled, on return from such leave, to be restored by the employer to the position of employment held by the employee when the leave commenced, or to be restored to a comparable position with comparable employment benefits, pay and other terms and conditions of employment. The taking of family leave shall not result in the loss of any employment benefit accrued prior to the date on which the leave commenced. Nothing in this section shall be construed to entitle any restored employee to the accrual of any seniority or employment benefits during any period of leave, or any right, benefit or position to which the employee would have been entitled had the employee not taken the leave.
