consistent with past research (Ibarra, 1992; Ibarra, 1995, Ibarra & Andrews, 1993; Krackhardt,<br />

1990; Morrison, 2002), it may have limited the number friends who employees selected.<br />

Certainly, employees indicated that they had few friends in the organization relative to advice<br />

ties. The stringent definition <strong>of</strong> friendship ties may have limited the effect <strong>of</strong> friendship ties on<br />

similarity in <strong>perceived</strong> <strong>organizational</strong> <strong>support</strong>. Employees who are only friends in the context <strong>of</strong><br />

the organization may actually spend more time discussing their perceptions <strong>of</strong> the organization<br />

than employees who are friends both inside and outside <strong>of</strong> the organization, because individuals<br />

who are friends outside the organization may have more to talk about that does not concern the<br />

organization. In recent studies, some <strong>social</strong> networks researchers allowed employees to select<br />

whomever they considered to be their friends, reasoning that employees have different<br />

definitions <strong>of</strong> what a friend is, and that employees’ personal definition was most relevant (e.g.<br />

Dabos & Rousseau, 2004). Therefore, the results concerning friendship ties in this study should<br />

be interpreted with caution.<br />

A third potential limitation <strong>of</strong> this dissertation is its utilization <strong>of</strong> a sample consisting <strong>of</strong><br />

employed undergraduate students who worked 25 hours per week. These employees differ from<br />

more traditional employees because they do not view the organization for which they work as a<br />

long-term employment option. However, as employees adopt more careerist attitudes towards<br />

the organizations that they work for (Feldman, 1991), voluntary turnover increases as employees<br />

job-hop, and contingent workers become more common in organizations (Tekleab et al, 2003),<br />

this may not be as great a concern, as the employees in this sample may be quite similar to<br />

contingent employees or careerist employees who have no intention <strong>of</strong> remaining with the<br />

organization in the long term. However, these employees may not have the same expectations<br />
