Second, the social insurance system in Thailand provides the unemployment insurance (UI) benefit to seasonal unemployed. In 2004, when the unemployment insurance benefit was started, there were 50,318 beneficiaries. However, the growth of beneficiaries is accelerating when insured persons have learnt about the system. In 2005, the number of beneficiaries increases to more than 220 thousand, with the growth rate of 340 percent. This pattern could cause a large drain of the UI fund in the future. The current UI system penalizes those whose are employed.
