Workforce diversity can be defined as people working in a company coming from different nationalities. Not only different nationality, but also different origin, different age, different race and also different gender (http://www.slideshare.net/kumudu737sjp/workforce-diversity). In other words, a company or organization becomes an increasingly heterogeneous mix of people in terms of gender, age, ethnicity and sexual orientation (Naik, 2012). When we talk about workforce diversity, a business presents threats and opportunities. It is certain that workforce diversity can provide many opportunities or benefits to a company. The opportunities that this diversity can offer a company are to increase the company's creativity, increase its productivity, attract new customers and develop language skills among the company's employees. different experiences working in an organization who have come up with different ways to solve the problems facing the company in order to arrive at a good solution. The more ideas companies get from different people, the easier they find the solution to their problems with a good or different way to solve them. Increasing company productivity can be a gain through workforce mixing. When people from all cultures come together to achieve goals, the business can succeed through globalization and internationalization. Workforce diversity can diversify the customer base. This is a result of the provision of specialist skills and cultural awareness of staff. Staff coming from different countries have different cultural backgrounds, so a company that does business globally can be successful because the staff can understand the needs and wants of customers in each country. Language skills are important for a company or business to communicate with different businesses in different countries. Even though English can be considered as the language of global communication, to build good relationships with other people of the world, we need to know their language. This can become an advantage for a company with a diverse workforce because the employee can help the company understand their words as well as the meaning of those words (Lee, 2004). Workforce diversity can also pose a threat to a company in terms of discrimination. and stereotypes. Discrimination can occur in matters of nationality. When a company hires labor from another country in small quantity, the labor will become a minority group in that company..
