Öz The book titled Human Resources Management Challenges: Learning & Development focus on a variety of issues related to diversity of workforce and diversity management. As many researchers claim, the diversity relates to the factors that differentiate employees, such as age, gender, marital status, social status, level of disability, sexual orientation, religion, personality, physical and mental capabilities, moral values, culture, religion, even outlook. Nevertheless, the concept of diversity is not based only on differentiation related to workers’ attributes, but also on other issues, such as relationships between the organisation and workers, interests of organisations’ stakeholders etc. Diversity management is, on the other hand, perceived as an opportunity to increase the competitiveness of enterprises. Organizations might gain competitive advantage through the use of diverse workforce potential and by implementing proper structures and processes with the goal of maximising the ability of the employees to contribute to organizational objectives and to achieve the full potential unhindered by the group identities such as gender, race, nationality, age and departmental affiliation.
