The Awareness Group should be formed by two persons from the EC: a woman and a transgender or a non-binary person. As victims of sexual harassment are mostly women, it will be easier for the victim to talk to a person who have probably experience the same thing. It will also be easier for the victim to talk to a person they can identify with.
Moreover, cisgender men are not in the best position to decide whether an incident falls into the category of sexual harassment or not, especially when it is an ambiguous situation.
The protocol should also add the possibility to call for an external mediation if required. In some situations, there can be a conflict of interest. For instance, if people of the Awareness Group know the people involved and cannot have a neutral decision. An external mediator could make a more neutral decision.
