Good cause—hours

(a) To determine that an individual voluntarily left suitable work for good cause attributable to the employer, the Administrator must find, with respect to hours, that: (1) the individual's employer: (A) during the course of employment, substantially changed the hours established in the employment agreement and such change had a significantly adverse effect upon the individual; or (B) violated state or federal law governing hours of employment and such violation had an adverse effect upon the individual; or (C) required the individual to work irregular or excess hours which would endanger the individual's health or safety; and (2) the individual expressed his dissatisfaction regarding hours to his employer and unsuccessfully sought a remedy through those means reasonably available to him before leaving his employment. (b) A temporary reduction in working hours to less than full-time due to lack of work does not constitute good cause attributable to the employer for voluntarily leaving employment.
