"More than 90% of adults experience workplace bullying—that is, psychological and emotional abuse—at some time during the span of their work careers (Hornstein, 1996). The supervisors who inflict psychological abuse on subordinates represent one of the most frequent and serious problems confronting employees in today’s workforce (Yamada, 2000). Although the television news is quick to report the rare but sensational incidents of disgruntled employees returning to their former workplaces seeking revenge (e.g., “Office Rampage,” 1999), rarely do we see stories of employee humiliation and psychological violence perpetrated by more powerful organizational members. Research indicates a link between workplace abuse and workplace violence as the aggressor becomes increasingly more threatening to targeted employees (Namie & Namie, 2000). In addition to increased threats of violence from abusers (Leymann, 1990), employees who feel unfairly treated may express their anger and outrage in subtle acts of retaliation against their employers, including work slowdown or covertly sabotaging the abuser (Skarlicki & Folger, 1997). As reported in a government study, “The cost to employers is untold hours and dollars in lost employee work time, increased health care costs, high turnover rates, and low productivity” (Bureau of National Affairs [BNA], 1990, p. 2). Employee emotional abuse (EEA) is a repetitive, targeted, and destructive form of communication directed by more powerful members at work at those less powerful."
