European legislation prohibits four different types of discrimination;
direct discrimination,
indirect discrimination,
harassment,
instruction to discriminate.
It also provides protection for victims and witnesses of discrimination against retribution.
Direct discrimination takes place when an employer treats someone worse than someone else in a comparable situation, in relation to the different grounds for discrimination.
Indirect discrimination occurs when a practice, procedure or rule that applies to everyone has a negative effect on some people. The measures seem neutral at first, but actually discriminate against certain people.
Harassment can take the form of undesirable behaviour, bullying or other behaviour that has a hostile, derogatory or degrading situation as its aim or effect.
Instruction to discriminate occurs when a person incites another person to discriminate a third party.
Protection against retribution: the law also stipulates that victims and witnesses of discrimination are protected against retribution.
