1 Unemployment insurance payments (benefits) are intended to provide temporary financial assistance to unemployed workers who meet the requirements of State law.  Each State administers a separate unemployment insurance program within guidelines established by Federal law.
Known as Emergency Unemployment Compensation (EUC), these benefits are organized in tiers. They are provided in addition to the about 26 weeks in standard state unemployment benefits. States will, of course, vary in terms of how many weeks of unemployment they offer. Tier 1 for EUC is 14 extra weeks and is available for all states, regardless of how high your state's unemployment rate is.
