New York Consolidated Laws, Correction Law - COR § 153. Conditions of Employment

(a) The rates of pay and other conditions of employment will not be less than those paid or provided for work of similar nature in the locality in which the work is to be performed.

(b) The commissioner finds, after consultation with representatives of local union central bodies or similar labor union organizations, that such employment will not result in the displacement of employed workers, impair existing contracts for services, or be applied, except where a prisoner is to be hired by an employer for whom he worked prior to his conviction, in skills, crafts, or trades in which there is a surplus of available gainful labor in the locality.
