How can you find harmony between European countries on regulations and legislation concerning the workspace with respect to country's sovereignty?

We foresee a limited influence on how country's sovereignty will affect the corporate workspace. Since companies are operating globally nowadays the original ties with natural roots towards one nation will vaporise. Especially, when more and more people with different cultural and national backgrounds join the workforce and enter top level management positions. Therefore, the dominance towards country sovereignty will evolve towards a global culture.
