Migrants must work for three years to be eligible for jobs in most sectors like EU nationals. Migrant entrepreneurs are also excluded from certain sectors. Migrants can renew most work permits, but are only partially secure since they lose their residence permit if made unemployed, no matter how long they have worked in Greece. Migrants are not supported by labour market integration measures to facilitate the recognition of their skills and qualifications, to reduce their unemployment, improve their level of Greek for work, or promote their training. Migrants would enjoy even more favourable workers' rights if they could change their employer, job or industry sooner.
