The more important the solution to a problem, the less she may be sought to provide it. In fields such as science, where good ideas and an individual's reputation among her peers are often the main determining factors in being rated by an employer, the effects of this type of prejudice can be overwhelming. Sexual prejudice can take more subtle but just as devastating forms. Older male co-workers may be happy to include him in their Friday lunch group, an impromptu basketball game, or other social endeavors, but may feel awkward about including his female counterpart. Similarly, there may be a shortage of mentors, or role models, available to the professional woman.
Mentors are valuable people.
They are like professional parents who take more than a passing interest in a younger, less experienced colleague. They offer constructive criticism and help develop professional attitudes. Along with friendly colleagues, they can help you develop your identity as a professional, your professional standards, and your self-confidence. However, an older male can feel awkward being a mentor to a young female. If he is her supervisor, he may not offer criticism that can be of value because of his inexperience or awkwardness in dealing with a female professional.
