Background Nursing requires a high load of emotional labour. The link between nursing, emotional labour and the female sex, complicates the figure of the male nurse, because masculinity is associated with physical or technical (rather than emotional) and moreover is defined in contrast to femininity. Our objective was to understand how emotion management is described by male nurses who work in the paediatrics department of a Spanish tertiary hospital. Methods Qualitative descriptive study. The participants were selected through intentional sampling in the paediatrics department of a Spanish tertiary hospital. We conducted semi-structured interviews until reaching data saturation. We carried out a content analysis, using Lincoln and Guba’s definition of scientific rigour. Results We identified two key themes in the data: 1) Stereotypes related to the emotional aspects of care: Participants took for granted some gender stereotypes while questioning others and defended alternative ways of managing emotions related to care. 2) Emotion management strategies: Participants described keeping an emotional distance, setting boundaries, relativising problems and using distraction and humour. Discussion Nursing care is conditioned by gender roles and stereotypes that present men as less capable than women of feeling and managing emotions. However, emotion management is necessary in nursing care—especially in paediatrics—and our participants reported using strategies for it. Although participants continued to interpret care in terms of traditional roles, they contradicted them in adapting to the emotional labour that their job requires. Conclusions New behaviours are emerging among male nurses, in which care and emotion management are not exclusively the purview of women. Our participants reproduced some gender stereotypes while disrupting others, and they tended to cling to the stereotypes that were favourable to them as male nurses. As we work towards a gender-neutral profession, these results represent a first step: male participants reported that they provide care and manage their emotions as well as (or better than) women. However, because they substantiated their claims by drawing on negative stereotypes of women, further progress must be made.
