Generelt kommer disse skævheder kun frem i lyset, når mennesker krydser grænser for at arbejde og opdager, at deres erhvervsmæssige status ændres og dermed også deres ret til social sikring og arbejdstagerrettigheder.
Generally of course these only come to light when people want to cross borders to work and find that their employment status changes and thus their rights to social security and employment-related rights change as well.
