Resources and relationships: Social networks and mobility in the workplace
Weexaminehow the structureand contentof individuals'networksin the workplace affect intraorganizational mobility. Consistent with prior re- search, wefind thatan individual'smobilityis enhancedbyhavinga large, sparse network of informal ties for acquiring information and resources. However,in contrasttopreviouswork,we emphasizethe importanceof con- sistent role expectationsfor performanceand mobility.Wefind evidence that well-definedperformanceexpectationsare more likely to arise from a small, dense networkof individuals.Wedevelopa typologyof networkcontentsand documentthe interactionbetween networkstructureand content in analyses of mobility among employees of a high-technologyfirm. Wealso examine how the effects of tie durationon mobilityvary by tie content. Wediscuss the implicationsof our resultsfor theoryand researchon networksand organi- zational mobility.
