PurposeThe purpose of this work is to comparatively study human resources management (HRM) areas in Brazil, at the national level, analyzing how companies considered labor market and labor relations aspects when building their strategies and when configuring people management models in place in the country (2014–2019), based on local conditions.Design/methodology/approachThe subject was approached through qualitative analysis, encompassing document survey, systematic literature review, specialists' panel discussions, eight focus groups (43 human resources [HR] managers), interviews (16 union members), applying institutional approach to people management.FindingsIn regards to labor market and unions, HR areas faced different conditions across Brazilian regions. They have dealt with those influences on their strategic and quotidian decisions in an unstructured fashion. HR areas remain constructed as traditional, adjuvant and far from strategic level.

It enhances the knowledge on HRM areas scope and their articulation toward labor market and relations.
