N.Y. Mil. Law § 252
No association or corporation, constituted or organized for the purpose of promoting the success of the trade, employment, or business of the members thereof, shall by any constitution, rule, by-law, resolution, vote, or regulation, discriminate against any member of the organized militia of the state of New York, because of such membership in respect of the eligibility of such member of the said organized militia to membership in such association or corporation, or in respect of his right to retain said last mentioned membership; it being the purpose of this section and the section immediately preceding to protect a member of the said organized militia from disadvantage in his means of livelihood and liberty therein but not to give him any preference or advantage on account of his membership of said organized militia. A person who aids in enforcing any such provisions against a member of the said organized militia with the intent to discriminate against him because of such membership, is guilty of a misdemeanor.
