Gentlemen,
There is no international HR as such, although labor legislation and business practices in different countries establish various benchmark HR practices that may have both local and global applications.
For example, the benchmark levels in the USA, Canada, Australia, and Gulf countries are similar. African benchmarks vary slightly from company to company within the African continent.
In Europe, businesses are governed by European Union employment laws, and their implications determine the HR practices in Europe, which is further divided into East and West Europe due to the transition to the European Union.
