Is it permissible to employ a young woman as a secretary in an information technology company, given the failure to employ young men in this position and the presence of other employees and students at the headquarters?

It is not permissible to employ a girl in this company due to the unlawful mixing with men and the temptation it poses for her and for young men. Losing out in this world by employing an unsuccessful young man is better than losing out in religion by employing a girl who causes temptation.
