Final answer:
One legal reason for discharge under antidiscrimination laws is when the discrimination passes the rational basis test, such as public safety or academic requirements for education, both of which are deemed legitimate reasons.
Step-by-step explanation:
One example of a reason for discharge that is not illegal under antidiscrimination laws is when discrimination is based on a rational basis test. Specifically, if there is a legitimate government interest that is rationally related to the discriminatory practice, such as public safety, the act is considered legal.
For example, laws that prevent blind individuals from driving are based on safety concerns and are therefore legally justified, even though they differentiate based on disability. Similarly, educational institutions can legally refuse admission to students who do not meet certain academic criteria because those students may lack the necessary skills or knowledge to succeed in the programs offered.
