Each employer shall conduct recruitment and institute hiring practices in such a way as to assure that members of the protected classes as defined in § 599 are given fair notice of job vacancies, are given opportunities to apply for vacancies, and are given consideration for employment in all vacancies on bases which do not discriminate on grounds prohibited by law.
Hiring and job assignment practices shall include steps designed to assure that the effects of past exclusion of minorities, women, disabled persons, or other protected classes from all or part of the employer's work force are not carried forward into the future.
