To test the effects <strong>of</strong> <strong>social</strong> <strong>influence</strong>, I examine interpersonal similarity in POS between<br />

employees and their weak and strong friendship ties, weak and strong advice ties, weak and<br />

strong role model ties, weak and strong role model-advice ties, weak and strong role model-<br />

friendship ties, and weak and strong role-model-friendship advice ties. While all <strong>of</strong> these ties are<br />

considered, I only <strong>of</strong>fer hypotheses for strong ties that exist between employees. This is because<br />

research on <strong>social</strong> networks shows that because weak ties characterized by infrequent interaction<br />

are unlikely to be related to similarity in perceptions (Erickson, 1988). I provide hypotheses<br />

only for strong advice ties, strong advice-role model ties, and strong friend-advice role model<br />

ties because I was most interested in how the exchange <strong>of</strong> information related to the job and the<br />

organization was related to similarity in POS among employees. I included a hypothesis for<br />

strong friendship ties to test the associative and comparative functions <strong>of</strong> <strong>social</strong> comparison<br />

theory. Chapter 4 contains the results for all different combinations <strong>of</strong> strong and weak ties<br />

relevant to the study.<br />

In addition, I examine employees’ relationships with coworkers rather than their<br />

relationships with supervisors (although I control for the effects <strong>of</strong> employees who occupy<br />

leadership positions in the organization). This is not to imply that supervisors are not a source <strong>of</strong><br />

information for employees. Morrison (1993) argues that supervisors are an important source <strong>of</strong><br />

information for feedback, role demands, and expectations. However, employees are less likely<br />

to ask their supervisors questions about the extent to which they are <strong>support</strong>ed by the<br />

organization because they would likely believe that responses from supervisors related to this<br />

issue are biased. Further, employees will likely discuss perceptions <strong>of</strong> <strong>support</strong> with coworkers<br />

because they are more easily accessible (Morrison, 1993; Ostr<strong>of</strong>f & Kozlowski, 1992) and will<br />

serve as a better comparison for employees because they are at similar levels in the<br />
