Job satisfaction is an essential component of teacher motivation, performance, and retention. Teacher job satisfaction is primarily affected by workplace conditions. This paper analyzes data from over 37,000 public school teachers from the 2011--2012 Schools and Staffing Survey. Hierarchical ordinal logistic regression was utilized to analyze effects of school rule enforcement and teacher victimization on job satisfaction. Findings indicated that teachers who perceived higher enforcement of school rules had higher job satisfaction. In particular, consistent enforcement of rules by school administrators had a significantly greater effect on satisfaction than collegial enforcement of rules. Findings also indicated that teacher victimization has a significantly negative effect on job satisfaction. Consistent enforcement of school rules may reduce instances of student misbehavior and teacher victimization, helping reduce teacher stress and anxiety, leading to greater job satisfaction. Implications for policy and practice are explored, examining what administrators can do to protect teachers and improve satisfaction.
