If discrimination is observed it must be challenged, if not then the individual observing would then be in the wrong and would be, in a way, contributing to the discrimination. To promote change people can practice active participation by doing as much as possible to support the part of individuals lives they cannot manage for themselves. Individuals can then have the feeling of isolation reduced and realise their value. This in turn promotes self esteem, encourages them to take control and make their own decisions, and this then helps to eliminate and form of abuse or discrimination.
A quick and effective complaints procedure promotes change to let the individual who how seriously the discrimination which has been witnessed has been taken, and also the consequences of the discrimination.
