[Excerpt] The federal-state Unemployment Compensation (UC) program provides income support to eligible workers through the payment of UC benefits during a spell of unemployment. UC benefits are available for a maximum duration of up to 26 weeks in most states. Unemployment benefits may be extended for up to 13 or 20 weeks by the Extended Benefit (EB) program under certain state economic conditions. For information on the temporary, now-expired Emergency Unemployment Compensation (EUC08) program, which provided additional unemployment benefits depending on state economic conditions during the period of July 2008 to December 2013, see CRS Report R42444, Emergency Unemployment Compensation (EUC08): Status of Benefits Prior to Expiration. Certain groups of workers who lose their jobs because of international competition may qualify for income support through Trade Adjustment Act (TAA) programs. Unemployed workers may be eligible to receive Disaster Unemployment Assistance (DUA) benefits if they are not eligible for regular UC and if their unemployment may be directly attributed to a declared major disaster. Former civilian federal employees may be eligible for unemployment benefits through the Unemployment Compensation for Federal Employees (UCFE) program. Former U.S. military servicemembers may be eligible for unemployment benefits through the unemployment compensation for ex-servicemembers (UCX) program. The Emergency Unemployment Compensation Act of 1991 (P.L. 102-164) provides that ex-servicemembers be treated the same as other unemployed workers with respect to benefit levels, the waiting period for benefits, and benefit duration. This report describes two kinds of unemployment benefits in detail: regular UC and EB. The report explains their basic eligibility requirements, benefits, and financing structures. As of the date of this report, EB is not currently available in any state.
