Diversity in the workplace today is a strategic issue for the organization, which, depending on how addressed, becomes an advantage or a threat. In today's multicultural world, it is important not only to accept diversity, but also to manage it well, in order to achieve the best results.

All of the above proves that the role of managing the diversity on human recources in achieving performance is crucial and is becoming the most important preoccupation of today's managers.
