Under Michigan law, it is unlawful to discriminate in a training or apprenticeship program on the basis of race, color, religion, sex, national origin, age, disability, height, weight, or marital status, unless a characteristic is a bona fide occupational qualification (BFOQ) reasonably necessary to the operation of the business. The burden of proving a BFOQ is on the employer (MI Comp. Laws Sec. 37.2205, Sec. 37.1205).
