(b) Benefits based on service for an educational institution or an institution of higher education in other than an instructional, research, or principal administrative capacity, shall not be paid to any individual for any week of unemployment which begins during the period between two successive academic years or terms of the employing educational institution or institution of higher education, provided the individual performed those services for the educational institution or institution of higher education during the first such academic year or term and, there is a reasonable assurance that such individual will perform those services for any educational institution or institution of higher education in the second of such academic years or terms.
If compensation is denied to any individual for any week under division (I)(1)(b) of this section and the individual was not offered an opportunity to perform those services for an institution of higher education or for an educational institution for the second of such academic years or terms, the individual is entitled to a retroactive payment of compensation for each week for which the individual timely filed a claim for compensation and for which compensation was denied solely by reason of division (I)(1)(b) of this section. An application for retroactive benefits shall be timely filed if received by the director or the director's deputy within or prior to the end of the fourth full calendar week after the end of the period for which benefits were denied because of reasonable assurance of employment. The provision for the payment of retroactive benefits under division (I)(1)(b) of this section is applicable to weeks of unemployment beginning on and after November 18, 1983. The provisions under division (I)(1)(b) of this section shall be retroactive to September 5, 1982, only if, as a condition for full tax credit against the tax imposed by the "Federal Unemployment Tax Act," 53 Stat. 183 (1939), 26 U.S.C.A. 3301 to 3311, the United States secretary of labor determines that retroactivity is required by federal law.
