Workplace diversity:
The compositional differences among people in a work unit are referred to as diversity. This encompasses the various attributes that individuals bring to an organization, such as cultural background, race, gender, age, personality, and work experience. Understanding and managing workplace diversity is an essential part of creating an inclusive and effective work environment.
On the broader scale, cultural diversity within different societies contributes to the variety of experiences, perspectives, and skills that can contribute to a more dynamic and innovative reality. When examining the practice where differences between low-end and high-end jobs become greater and there is a decrease in mid-level jobs, the term that describes this phenomenon is polarization. This trend can reshape the workforce and economic landscape of a society, leading to varied implications for workers at different skill levels.
