The forces of globalization and the European mobility policies contribute to the diversity of the European labor market.There is a common acceptance that workforce mobility and diversity are positive aspects for competitiveness. However, as pointed by several researchers and by the European Monitor for Change, workforce mobility and diversity does not come without challenges, especially for companies, and should be seen carefully for each particular case.Company culture is determined by the corporate DNA but also by local and national culture. It is therefore likely that significant cultural differences will emerge between local employers and foreign employees with regard to several aspects like leadership, work ethic or HR policies. To be able to face the impact of cultural diversity, companies should have a clear cultural workforce diversity strategy, which should permeate all key organizational processes.The project aims at improving the multi-cultural recruitment processes in European companies to increase the effectiveness of workforce diversity, by addressing well identified problems/challenges:1) Lack of awareness on the incorporation of workforce diversity in corporate strategy2) Limited skills and knowledge on culture and diversity by HR and recruitment professionals3) Gap in the market with regard to training on culture and workforce diversityBased on an initial extensive and in-depth research in partnership with several European Business Schools and HR professionals across Europe, we propose developing and running an extensive training program for effective recruitment across cultures. This will ultimately help ensuring the effectiveness of workforce diversity, enhancing competitiveness and reducing recruitment and retention costs.
