§ 140. Wearing industry badges, or other insignia of identification by
unauthorized persons. An employer of labor may adopt a badge, or other
insignia of identification, to be worn or displayed by the employees for
the purpose of identification while upon the premises of the employer
and may post a notice of the adoption of such badge, or insignia, near
the main entrance of such premises. Such employer may deposit with the
department of labor a replica of such badge or insignia, and such
department shall, if such badge or insignia be distinctive, issue to
such employer a certificate authorizing the use thereof for the purposes
of this section. Any person who, after the approval and adoption of such
badge, or insignia, without authority or permission of the employer
adopting the same, wilfully wears such badge or displays such insignia,
or any facsimile or any imitation thereof, or uses the same to obtain
admittance to or remain upon the premises of the employer, is guilty of
a misdemeanor.
