(

a) Any base period employer may, within days after mailing of a notice of computation under subdivision (

a) of

Section 1329, submit to the department facts within its possession disclosing that the individual claiming benefits is rendering services for that employer in less than full-time work, and that the individual has continuously, commencing in or prior to the beginning of the base period, rendered services for that employer in such less than full-time work. (

b) The department shall consider facts submitted under subdivision (

Section 1252, unemployed in any week on the basis of the individual having less than full-time work, and that the employer submitting facts under this

section is a base period employer for whom the individual has continuously, commencing in or prior to the beginning of the base period, rendered services in such less than full-time work, that employer’s account shall not be charged, except as provided by

Section or if the department determines pursuant to

Section 1026.1 that the employer’s reserve account should not be credited, for benefits paid the individual in any week in which such wages are payable by that employer to the individual. The employer may appeal from a ruling or reconsidered ruling to an administrative law judge within days after service of notice of the ruling or reconsidered ruling. The 30-day period may be extended for good cause, which shall include, but not be limited to, mistake, inadvertence, surprise, or excusable neglect. The director shall be an interested party to any appeal.

The department may for good cause reconsider any ruling or reconsidered ruling within either five days after an appeal to an administrative law judge is filed or, if no appeal is filed, within days after service of the notice of the ruling or reconsidered ruling. (

section shall become operative on July 1, 2015.
