This article presents the results of a systematic literature review on religiosity and spirituality, particularly in the work context. We aimed to verify the state-of-the-art of scientific production related to these themes. To achieve the proposed objective, we identified 312 articles published in journals in the period between 1960 and 2018 using a rigourous method of analysis and sorting, which resulted in 52 appropriate studies. The analyses presented are based on the three bibliometric laws: those of Lotka, Bradford and Zipf. (...) This article brings contributions that encompass four approaches: measurement scales of spirituality and religiosity; behavioural benefits of religiosity in individuals; insertion of religiosity and spirituality in social service practice; and research directions. This research presents technical and managerial implications to provide theoretical support for the creation of programmes and/or practices of spirituality and religion in the workplace as an effective strategy, towards ethical attitudes. Also, this study contributes to the methodological achievement of SLRs in the field of religion in the workplace, highlighting an effective method for thematic mapping, and holistically identifying new research topics and directions, especially because of the several guidelines presented.
