Personal networks of white-collar workers are examined to determine how the structural properties of personal networks affect workers' motivation and job commitment. We have conducted a series of surveys, survey of personal networks and job of white-collar workers at the advanced info-communication enterprise (1998-1999), at an electronics company (1999), and of young white-collar workers of various industries (2000). Analyzing these survey data, we have found ; 1) the structure of white-collar workers networks differ by their age, gender and status ; 2) they show little differences by job ; 3) structural properties of workers' personal networks correlate with their work motivation and commitment ; and 4) creativity and information-gathering ability of workers also correlate with their' work motivation and commitment. Although we started with a hypothesis that promotion speed correlates with structural properties of white-collar workers' personal networks, we could not find strong evidence to support the hypothesis. We presume this is due do the fact majority of white-collar workers under survey are promoted by their seniority, not by direct performance.
