A second one is the expansion of economies and businesses globally, thus increasing the need for larger workforces.
A third is that the compensation levels of these workforces vary dramatically across countries, even for comparably skilled
workers. The fourth reason is, and following from the previous three, is that firms see that they are able to gain and sustain a global competitive advantage when they manage their workforces effectively (Bryan,2010;Gupta&Govindarajan,2001; Porter, 1990 ). To do so successfully, we propose that these firms must confront the reality of several global talent challenges and develop global talent management initiatives to address these challenges.
