Social justice icons, like Rosa Parks, Mahatma Ghandi, Martin Luther King, Jr. and César Chávez, known for their tireless, courageous leadership initiating societal changes that have benefited many, lead the way for contemporary professional psychologists. These leaders opened pathways for inclusive principles and practices in education, employment, and political contexts. At the same time, professional leadership on behalf of multicultural and social justice issues in professional organisations and other contexts is known to be challenging. Biases and assumptions, micro-aggressions, and ignorance of experiences with interpersonal oppression are communicated daily. In multiculturally diverse global societies, social justice leadership is in great demand. Psychologists are encouraged to develop multicultural competencies in educational, research, and organisational practices and emulate the social justice icons.
