A/HRC/32/50/Add.1 victims of torture, are detained under particularly problematic conditions. 26 Following a visit to Greece in 2013, the Working Group on Arbitrary Detention made reference to large-scale round-up operations in which foreigners were detained on discriminatory grounds and released shortly thereafter.27 59. The European Court of Human Rights has repeatedly condemned Greece for the conditions of detention and failure to provide access to the asylum procedure. 28 In particular, during the first half of 2015, there were 11 noteworthy cases involving refugees and asylum seekers, most of them concerning alleged violations of articles 3 and 5 of the European Convention on Human Rights, on the prohibition of inhuman or degrading treatment or punishment, and the right to have the lawfulness of one’s detention decided speedily by a court, respectively.29 F. Migrant workers 60. The percentage of non-nationals in Greece was reported as being 7.7 per cent of the total population in 2014 and has been growing since that time.30 It has also been reported that the current economic crisis and growing xenophobia among the population have reduced immigrant registration. Therefore, the actual size of the foreign-born population is estimated to be significantly higher, between 1 million and 1.3 million people, comprising as much as 10 per cent of the population. Migrants come from 120 countries, the majority of them —around 90 per cent—from the Balkans, countries of the former Union of Soviet Socialist Republics and South Asia. 61. Migrants offer low-paid unskilled labour, thus enabling small businesses in particular to face growing competition by reducing their costs. The weakening of social protection, the need for flexibility in labour relations and the restructuring of the economy have all contributed to the intensity of this phenomenon. At the same time, there has been a shift in the professional orientation of Greek nationals, who search for higher-quality jobs. Therefore, professions that are seasonal in nature (agriculture, tourism, construction and fishing) are often occupied by migrants who, due to economic hardship, have become a flexible workforce.31 62. The priority awarded to Greek and European Union citizens in the labour market also makes it difficult for other foreigners to find employment. This restriction is aggravated in the current context of economic crisis and xenophobia in Greece, with migrants being the most-affected group. Unemployment rates among migrants reached 40.5 per cent in 2013, double the rate among Greek nationals. Social protection programmes have been known to discriminate on the basis of country of origin with regard to coverage of family members. 26 27 28 29 30 31 16 Médecins sans frontières, “Invisible suffering: prolonged and systematic detention of migrants and asylum seekers in substandard conditions in Greece” (April 2014), available from http://cdn.doctorswithoutborders.org/sites/usa/files/attachments/invisible_suffering.pdf.
