The research explores a new model of staff wellbeing across UK police custodial services (public and private). These services are unique for the fact that police sergeant custody officers are supported by detention officers who can be publicly or privately contracted, with the latter providing a heterogeneous mix never previously researched. The model informs a survey approach conducted across four English police forces. Drawing on a diverse literature which compares health and criminal justice professions, this study explores the possibility that private sector detention officers will report lower levels of emotional exhaustion and workplace stress and higher levels of personal accomplishment than their public sector counterparts. Multilevel analyses, supplemented by ANOVA and t tests, detected statistically significant differences for private sector detention officers regarding higher levels of emotional exhaustion and lower levels of personal accomplishment and workplace stress (with the stress result the only one in the predicted direction). However, results should be interpreted as sample specific linked to privately contracted detention officer disquiet with their then employer (since replaced). That said, the results provide a good exploration of the model's utility together with important lessons for model and survey development in the future.

United Kingdom Police custody is one of the most challenging of work environments, liable to excessive demands and reduced well-being. Being difficult to access, it is also a much-neglected area of research that has focused on one or two roles, rather than the full range available, and on individual-level research, rather than a more comprehensive multilevel understanding of how organizational culture and climate can simultaneously influence a range of well-being outcomes. The present longitudinal study explored all types of roles, in both the public and private sectors, across seven English police forces and 26 custody sites (N = 333, response rate 46.57%, with repeated returns = 370). The Integrated Multilevel Model of Organizational Culture and Climate (IMMOCC) was applied to examine the organizational-level influences on individual well-being. Results indicated that (1) custody sergeants were most vulnerable to low well-being, followed by publicly contracted detention officers; (2) shared leadership (a source of team cohesion) was linked to four of six well-being outcomes; (3) two sub-components of culture reflected tensions never acknowledged before, especially in respect of role; and (4) reverse relationships existed between well-being outcomes and the dimensions of culture and climate. The findings inform practical recommendations, including resilience training and the need to raise the status of police custody, while also highlighting concerns about private sector scrutiny that may be relevant to other professions.
