The researchers examined the impact of person-environment (P-E) fit, as defined by Holland's (1997) theory, on interpersonal conflict at work (ICAW) and workplace aggression. In addition, previous relationships found in the job satisfaction literature were examined in the present sample of 244 United States employees. Internet-based surveys were completed by 244 participants in the current research. Results of hierarchical multiple regression and correlational analyses demonstrated a negative relationship between P-E fit and ICAW. Replication of previous relationships was found between job satisfaction, P-E fit, and workplace aggression. Implications for P-E fit and workplace aggression research are discussed.
