Horizontal violence is a form of relational aggression in the workplace, a pervasive experience in the nursing profession (McKenna, Smith, Poole, & Coverdale, 2003). The term horizontal violence is used to describe cruel behavior between colleagues of comparable status, such as professional nurses, in the workplace. Research has shown a variety of disruptive peer behaviors that are harmful to the profession and healthcare systems (Farrell, 2001). However, little research has been conducted on “eating their young,” the horizontal violence that occurs among those with unequal power, such as nurses and students (Thomas & Burk, 2009). Several databases including Academic Search Premier, JSTOR, CINAHL, MEDLINE, and Cochrane were accessed using the keywords “workplace violence,” “nurses,” nursing students,” horizontal violence,” “bullying,” “oppression.” and “intergroup conflict”. The purpose of the literature search was to determine the prevalence of horizontal violence among new nurses and nursing students. Horizontal Violence Horizontal violence by nurses toward new nurses and nursing students includes methodical, unwelcome, or unprovoked behavior with the intent to upset, control, humiliate, harm, or segregate (Hutchinson, Vickers, Jackson, & Wilkes, 2006) . Horizontal violence can be stealthy and subtle (such as withholding information or spreading gossip) as well as obvious and direct, such as scolding in front of other staff, false reports, or threatening body language (Hutchinson et al., 2006). Other forms of experience, described in both nursing and non-nursing literature, include bullying, mobbing, intimidation and aggression (Farrell, 2001).
