Sec. 5. (a) As used in this section, the term "part-time worker" means an individual whose normal work is in an occupation in which the individual's services are not required for the customary scheduled full-time hours prevailing in the establishment in which the individual is employed, or who, owing to personal circumstances, does not customarily work the customary scheduled full-time hours prevailing in the establishment in which the individual is employed.
(b) The department may prescribe rules applicable to part-time workers for determining their weekly benefit amount and the wage credits required to qualify such individuals for benefits. Such rules shall, with respect to such individuals, supersede any inconsistent provisions of this article, but, so far as practicable, shall secure results reasonably equivalent to those provided in the analogous provisions of this article.
