Adapting to work in a foreign environment is a skill in itself A person who works for a time in Spain, Romania and Sweden, for example, has learnt to adapt to different cultural patterns and knows how to work best and to cooperate with people there. These are very valuable skills.
Someone working in a Latin country such as Italy, for example, would get used to managing flexibility, so when someone says '5 minutes’, they know that this may not be the same as 5 minutes would be to a German.
