Final answer:
Discrimination based on occupation could potentially be subject to the rational basis test, as employers might have a justifiable reason for treating employees differently based on job roles or duties. However, discrimination based on race, gender, or disabilities is generally considered unfair and is illegal under various laws.
Step-by-step explanation:
Discrimination is the unjust or prejudiced treatment of different categories of people or things, especially on the grounds of race, age, or sex. Employment discrimination specifically refers to differences in treatment in the labor market, where workers with the same skill levels and qualifications receive different pay or job opportunities because of their race, gender, religion, or other protected characteristics. When considering the types of discrimination that would not be considered unfair, one has to assess whether there is a justifiable reason for treating people differently that is not based solely on the aforementioned protected characteristics.
Based on the information presented, discrimination based on occupation could potentially be subject to the rational basis test. This means that if an employer has a rational reason for treating employees differently based on their job roles or duties, it might not be considered unfair discrimination. For instance, paying a manager a higher salary than an entry-level employee due to differences in their responsibilities is typically justified. However, discrimination based on race, gender, or disability, like blindness, is generally considered unfair and is protected against by several laws.
