§ 704-a. Unfair practices; performing arts. It shall not be an unfair
labor practice for an employer engaged in the performing arts to make an
agreement with a labor organization, of which performing artists are
members, covering employees engaged in the performing arts, or who, upon
their employment, will be so engaged, because the majority status of
such labor organization has not been established under the provisions of
this article or because such agreement requires, as a condition of
employment, membership in such labor organization after the seventh day
following the beginning of such employment or the effective date of such
agreement, whichever is later. Nothing in this section shall be
construed as to bar any proceeding brought pursuant to section seven
hundred five of this article.
