tokenism

Tokenism is the policy and practice of making a perfunctory gesture towards the inclusion of members of minority groups. The effort of including a token employee to a workforce usually is intended to create the appearance of social inclusiveness and diversity (racial, religious, sexual, etc.), and so deflect accusations of social discrimination. Typical examples of tokenism are purposely hiring a black man or woman in an occupation usually dominated by white people, or hiring a woman in a profession usually dominated by men.
