In this study, a qualitative, reflexive methodology was adopted with a postmodern philosophical foundation in order to examine the emotional labor of nurses working in prisons in England and Wales. Phase 1 of the study involved semistructured interviews with nine qualified, registered nurses from three adult prisons: two male establishments and one female. In phase 2 of the study, two of these nurses entered into a supervisory relationship with the researcher, with the researcher as clinical supervisor. Monthly clinical supervision sessions were held with both nurses over 6 months. Findings from this study suggest that the nurse working in prison experiences emotional labor as a consequence of four key relationships: the relationship with the prisoner patient, the relationship with officer colleagues, and the relationship with the Institution; the fourth relationship centers on the contradictory discourses the nurse engages with internally, and is referred to as the "intranurse" relationship. This relationship involves on-going internal dialogue between the two selves of the nurse: the professional self and the emotional "feeling" self. In order to manage the emotion work inherent in prison work, it is suggested that the development of emotional intelligence through clinical supervision and reflective practice is of significant benefit to both healthcare and discipline staff.
