Testing for the Invariance of a Causal Model of Friendships at work: an investigation of job type and needs
The relationship between workplace friendships and organisational outcomes were investigated. Employees from diverse industries responded to an Internet-based survey (n=445). A previously supported model of workplace relationships (Morrison, 2004) was cross-validated, confirming linkages between friendships at work and organisational outcomes. The model was invariant across groups reporting differing needs for affiliation, autonomy or achievement, but non-invariant across groups reporting occupying relatively less or more interdependent jobs. Results suggest that the interdependence of individuals’ jobs affects the salience of work friendships more than subjective needs.
