Discrimination criteria are listed in the various legal codes.
Their list evolves over time (new criteria, changes in titles).

Each member country of the European Union defines the criteria for protecting its citizens according to its own circumstances (history, societal issues, etc.):

Criteria for discrimination according to the penal code (applicable in everyday life in the fields provided for by law):

origin, sex, marital status, pregnancy, physical appearance, particular vulnerability resulting from their economic situation, apparent or known to the perpetrator, surname, place of residence, state of health, loss of autonomy, disability, genetic characteristics, morals, sexual orientation, gender identity, age, political opinions, trade union activities, whistleblower status, etc.

It is therefore important to note that the criteria may vary depending on the situation and the employee's status in the workplace.

Addendum :

According to the European Charter of Fundamental Rights, the criteria are defined as follows: sex, race, color, ethnic or social origin, genetic characteristics, language, religion or beliefs, political or any other opinion, membership of a national minority, property, birth, disability, age or sexual orientation.
