The pervasive myth of the United States as a "classless society" silences the reality of social class oppression in this country. This silencing has received little attention to date in group work training, research, and practice. Unmasking classism may generate anxiety for group workers and members alike, yet holds potential for significant growth in human relations. This article is intended to encourage group workers to engage in social justice by addressing the harmful intra- and interpersonal effects of classism as it manifests in group process. The author presents methods for attending to classism through self-awareness, group facilitation, assessment, and planning.
