The movement of employees around the world is critical for the international expansion of businesses. The COVID-19 global pandemic has placed employee mobility in the spotlight for many businesses as a result of employees working in different locations. How we work has shifted to a more dynamic and fluid way of working.

  • How is the business coping financially? Is our business model agile and flexible with achievable goals?
  • Can our workforce adapt to remote working?
  • What are some of the hidden risks of actions we are taking now in relation to Global Mobility?
