Det er meget vigtigt for arbejdstagere, der betaler til en forsikringsordning i en bestemt medlemsstat, at de ikke får problemer, når de vender tilbage til deres oprindelsesland, eller hvis de flytter til en anden medlemsstat for at arbejde.
This is very important for workers who pay social security in a particular Member State, whose lives will improve on their return to their country of origin and when they move to another Member State to work.
