Many people make the mistake of believing that sexual harassment is driven solely by a desire for sexual gratification. It is not. Many types of behavior constitute sexual harassment, or gender harassment, which are not driven by a desire for sexual gratification. For example, if a male supervisor ridicules, belittles, or subjects women to increased scrutiny, while treating men differently (better), it may constitute gender based harassment.
Therefore, when it is apparent that a dual standard based on gender is being used in the workplace, it may be unlawful and should be investigated.
