Unemployment benefits in Greece are administered through OAED (, Manpower Employment Organization) and are available only to laid-off salaried workers with full employment and social security payments during the previous two years. The self-employed do not qualify, and neither do those with other sources of income. The monthly benefit is fixed at the "55% of 25 minimum daily wages", and is currently 360 euros per month, with a 10% increase for each under-age child. Recipients are eligible for at most twelve months; the exact duration depends on the collected number of ensema "ένσημα", that is social security payment coupons-stamps collected (i.e. days of work) during the 14 months before being laid off; the minimum number of such coupons, under which there is no eligibility, is 125, collected in the first 12 of the 14 aforementioned months. Eligibility since 1 January 2013, has been further constrained in that one applying for unemployment benefits for a second or more time, must not have received more than the equivalent of 450 days of such benefits during the last four years since the last time one had started receiving such benefits; if one has received unemployment benefits in this period for more than 450 days then there is no eligibility while if one has received less, then one is only eligible for at most the remaining days up until the maximum of 450 days is reached.
