The present generation may not accept that the man is more motivated than a women as they have already proved otherwise. In fact  women are more motivated than men. .Definitely motivation is a defence against  discrimination.. 

Motivate is an inspiring guideline for assisting in once reasoning task for helping which may become the inspiration for him to carry out his action .If the end of a person is for discrimination than he should not be placed in the word of motivation.

Motivation is all the time for useful hints & never to  go against negative traits .

This is my personal opinion

To answer this question you must first define what motivation is. Then you'd have to come up with an objective way to measure it so that you could demonstrate the hired employee had a higher level. You'd also have to indicate in the job requirements that motivation will be part of the hiring equation. And you'd have to prove that your "instrument" did not have an inherent gender bias.

You might want to add "gender bias" to your search terms. If you search online for "avoid gender bias in hiring" you'll find some good material.

good greeting:

Women play increasingly indispensable roles in the national, international and family economy, but they still enjoy a less fortunate economic position than men. They face serious discrimination. Although women are no longer a reserve labor force, equal opportunities and treatment remain a distant goal. Women are constrained in terms of achieving all their suppliers' And contribute to economic development

The role of women in the economy can not yet be ignored or neglected More women are becoming fully committed to choice or because of economic pressures and are economically active through their working lives. Women are increasingly migrating to work in their countries and abroad. Women have entered some of the previously male-dominated jobs the man has a monopoly on office jobs are now women typically operated and figured high in the representation of women in managerial positions and in the categories of professional and technical has broken a lot of women glass ceiling (a barrier women find it difficult to progress behind in jobs Decision-making and important administrative functions and reflects social and economic discrimination) and are now occupying high-level positions. Despite their increasing participation in the labor force and some social developments, the majority of working women are still disadvantaged and disadvantaged for men. Different forms of discrimination continue within and outside the labor market, to change my legislators elected in the whole world is still partially represented in most national and international public administrative structures.

It is well known that cultural norms and social beliefs on gender roles play a role in determining what women and men have access to and the type of education. In most societies, women are expected to do household chores and take care of family members and children, although the work of women in the family budget is similar to that of men In many countries, this income has a significant role in keeping households above the poverty line.

In many Muslim countries, the legal status of women remains unequal in terms of marriage and inheritance. In Yemen, women still have to obtain the husband's consent to work outside the home, Kuwait, where women have limited opportunities to join the judicial corps as judges because of considerations related to tradition and religion and there is no legislative ban, as well as in Iraq, rejects some religious doctrines to allow ownership of agricultural land for women they receive from inheritance, and this limits their ability to work As well as access to loans and membership of agricultural associations. Gender discrimination in terms of inheritance also reduces the ability of women to engage in lucrative activities, as well as unequal treatment of citizenship. Women married to non-nationals in the Gulf States are punished, Education and work for men, let alone women.

We can link the issues relating to discrimination against women in the work into three groups as follows:

First: Supply in the labor market:

1 - Family responsibilities and limitations: Some societies impose on women to never work, especially after marriage and childbearing and if it must work is under the pressure of urgent economic need, women in our societies are still forced to choose between children and work or overcome the need to reconcile the duties of the job and family responsibilities and They may continue to falter in their profession if they can not reconcile the duties of the job and their domestic responsibilities, which may deprive them of working to improve their education and skills, which qualifies them to occupy higher jobs and here it is necessary to promote equal partnership between men and women in family life In society and focus on the responsibility of men and women in equal care for children sharing family responsibilities and be more equitable and must provide social support and our infrastructure to enable women and men to reconcile work and family responsibilities.

2. Inequality in education and training: - Education and training are necessary to achieve equality. Women's education and training levels are still lower, and women's numbers are still lower in the labor market and the supply of female labor is weaker than for men. Discrimination in girls' access to education continues to face many difficulties due to custom and marriage whereupon the girl's pregnancy early heavy domestic work from an early age and often result in the performance of teachers is weak or dropping out of the educational system. Women are often deprived of training and retraining opportunities at the level of the establishment in which they work because they lack seniority and qualifications compared to men or employers are aware that the returns from investing in women's training are inferior to men and this affects their chances of upgrading their skills, Its adaptive technology and changing production processes.

3. Inequality in access to productive resources: - Continuing in different forms. Women are economically active in various jobs ranging from wage labor to agriculture to the informal sector. However, legal barriers to land, natural resources, human capital and credit, as well as wage disparities, all impede progress Economic development of women.

The existence of programs to equip women to work more effectively in markets or to provide information or direct resources and to educate women to use new productive interventions and their means of acquiring credit to respond to economic opportunities, control their own resources and livelihoods and provide marketing channels for their products will be more productive

Very kind of you to answer in detail
