Don't mention it: Why people don't share job information, when they do, and why it matters

Network-based job search is especially likely to foster workplace segregation and limit status attainment when information flows through homophilous ties. This paper takes the perspective of information holders and examines how the use of strong versus weak ties - which tend to be homophilous and heterophilous, respectively - differs with characteristics of labour markets in which jobs are located. Using in-depth interviews with entry-level white collar workers I show that information holders with opportunities to mention specific jobs to specific people do so only 27% of the time. Because they hesitate to share information if they are uncertain the information is specifically sought, information flows more commonly to strong ties, whose career goals are more likely to be known. Information is more likely to be shared with weak ties if it concerns occupations for which one may be specifically credentialed, since receiving relevant training serves as signal of interest in such jobs. These finding suggest that the homophily of referrals and their inequality-generating effects may vary across occupations. (C) 2011 Elsevier B.V. All rights reserved.
