This research, which was conducted in two phases, explored the effects of intimate partner violence (IPV) on the workplace between 2005 and 2008. Phase One (Dataset 1, Phase One Data) examined the prevalence of IPV among employed individuals, how IPV affects the personal and professional well-being of employees, and its costs for employers. Researchers focused on two research questions:Does IPV affect employees, and, if so, how?What is the impact of IPV on organizations? Phase Two (Dataset 2, Phase Two Data) focused more specifically on the interactions between employed IPV victims and their coworkers, focusing on the following questions:Does work-related social support have positive effects on the well-being, attitudes, and behaviors of employed IPV victims?How and when will coworkers provide assistance to IPV victims at work?When and to whom will IPB victims disclose their victimization at work?What organizational conditions are associated with stronger feelings of hopefulness on the part of employed IPB victims?
