Which of the following is NOT a protected characteristic in discrimination cases?

In discrimination cases, the law protects individuals from unfair treatment based on certain inherent characteristics. Protected characteristics typically include aspects such as race, gender, and age, which are recognized by various anti-discrimination laws. These laws aim to prevent discrimination based on traits that individuals cannot change and that do not affect their ability to perform their job duties.

Experience level, however, does not fall under the category of protected characteristics. It is considered a variable that relates to an individual's qualifications, skills, and work history, which can change over time with learning and career progression. Discrimination based on experience level is generally viewed as a matter of job qualification rather than an issue of inherent personal identity or status. Thus, it does not receive the same legal protections as the other mentioned characteristics.
