The professional habitus and values of social work, are challenged when social workers encounter client aggression. The current study was set up to understand the ways by which workers confront and cope with client aggression. In-depth interviews were conducted with 40 social workers in general municipal services. The participants included district managers, agency managers, supervisors, social workers and administrators. We identified a process consisting of four stages: (1) Rationalization, minimization, and denial of client aggression, including self-blame; (2) Emotional reactions, including hurt, anger, helplessness and shame; (3) Reevaluation of one’s beliefs, attitudes and values; (4) Behavioral transformation. The process of going through the four stages is not always linear, and workers may go back and forth between stages. The results are discussed in terms of the gaps between social workers’ values and the reality they are facing. Such gaps serve as an engine of change, explicated by theoretical concepts of social judgment theory.
