Many international businesses understand the advantages of training its employees to speak multiple languages. It is often the case that they even became international businesses because they employed tools to improve their relationship with foreign customers.
One such tool is language training. Like any worthwhile skill, language training requires a decent investment of time and resources in order to become a worthwhile business investment.
Eventually, employees who are fully trained in a foreign language will be able to operate in and from countries of that language. Not only will they gain the ability to do this, but they will also be able to do so in an efficient and savvy manner.
Savvy in regards to how they operate in that country. It is one thing to be able to work in a country that is foreign, but to be able to do so in a progressive way that improves business relations is a completely different ability.
