The recent literature shows that improving organizational support, increase trust performance via different domains (i.e. organizational identification) and that improving support for breastfeeding increase lactation rates and duration. Breastfeeding support in the workplace is one component that contributes to a mother’s ability to continue to breastfeed once she has returned to work. This is HRM practice that facilitate work-life balance. Working mothers have, at least, two roles: mother and worker and when mothers return to work must manage both identities. Is lactation a way to keep both identities connected? Is organizational support of breastfeeding a way to improve organizational identification? The aim of this paper is to analyze a hierarchical model to explain how managers and co-worker support to breastfeeding predict trust and organizational identity in a sample of Spanish working mothers (N = 1028) Material and Methods. To analyze the indirect effect, it was tested a mediation model with PROCESS in two random samples and carried out SEM to confirm structural relationship in the proposed model. Results: Outcomes reveal effects of managers´ support to lactation and vertical trust in organizational identity but not in co-worker path. Conclusion: The findings suggest the manager role in maintaining trust from working women and create and maintenance organizational identification.
