Within the human rights system that's generally how things work in terms of an actual individual complaints process. The Human Rights Act itself sets out norms that employers and service providers must be aware of, so it also has a role to play in regulating the conduct of businesses and employers. However, you're absolutely right that when an individual seeks to bring a complaint, they have to do so. They come before the commission. The commission has its own powers and abilities to investigate the alleged discrimination. It's a relatively informal process, but again, the burden, as with all discrimination complaints, would rest on the individual bringing it forward in the event they felt that discrimination had occurred.
