Isn't that a Title VII / EEOC violation? Woman-only gyms - like sex-segregated toilet facilities - operate "because of a compelling and overriding privacy issue". This can extend to woman-only requirements for employees at such businesses, since some states have made an exception for health and wellness centers.<p>These exceptions don't apply to taxis, that I can tell. For example, in LivingWell (North), Inc. v. Pennsylvania Human Relations Commission (1992), the courts defined a three-part test:<p>> A business must establish a factual basis for believing that not excluding members of one sex would undermine its business operation; that its customers’ privacy interests are entitled to protection under the law; and that no reasonable alternative exists to protect the customers’ privacy interests.<p>Taxis don't have a privacy interest. Plus, are there really no other reasonable alternatives?<p>(See <a href="http://download.ihrsa.org/gr/womenonly.pdf" rel="nofollow">http://download.ihrsa.org/gr/womenonly.pdf</a> for some of the information about the the law allows sex-segregated gyms.)
