What does it mean to be discriminated against at work?

To be discriminated against at work means that the employee is being protected by specific legal categories, such as the color of their skin or their ethnicity. When an employer violates employee’s rights to be free of discrimination, the employer is treating the employee worse because of this protected category, mainly the color of their skin or their ethnicity.

There are other categories the law protects, also. These are what we call discrimination claims.
