Using your Ties to Get a Worse Job? The Differential Effects of Social Networks on Quality of Employment in Colombia

International audience ; This article examines the effect of social networks (SNW) by investigating how mobilizing family, friendship or kindship ties in job searches affects the quality of employment (QoE) using quantitative and qualitative data. Drawing from socioeconomic literature on the segmented labor market, the authors propose an original and multidimensional measure of job quality and a fruitful estimation of the effect of SNW on QoE that allows for dealing with complex inter-groups heterogeneity. Using the Great Integrated Household Survey and a sample on Bogota's workers in 2013, they provide empirical support that the use of ties is negatively correlated with the QoE for those who are vulnerable. Likewise, the use of social relations is not significant for protected workers. Complemented by focus groups interviews, these results raise questions about the difference prevailing in relational practices between necessity networks for precarious workers and opportunity networks for protected workers in the Colombian capital.
