This study explored the outcomes of, and adaptive strategies employed by library personnel in performing afternoon/nightshift in a mega-city like Lagos, Nigeria. The Maslach Burnout Theory was used as the explanation framework for burnout concepts such as; emotional exhaustion, cynicism, depersonalisation and individual accomplishment and other matters allied with longstanding, unsolved job-induced stress. The qualitative methodology guided by a phenomenological research paradigm, which is an approach that focuses on the commonality of real-life experiences in a particular group, was used. A focus group discussion among purposively selected library personnel was used as a method of data collection from staff who are involved in afternoon/nightshift. The participants were selected using convenience sampling technique in which all categories of staff in the cataloguing unit involved in nightshift were included in the sample because of their representative characteristics. The phenomenological approach was adopted in conducting the study to enable a deep elicitation of data for understanding the phenomena as it is reasonable and from a broad interpretation of perspectives drawn from individual experiences. The questions posed were meant to shed light on issues relating to the participants' maintenance of a work-life balance in-situ with performance of nightshift duties. The study discovered that library staff experience emotions of fear, insecurity, stress and financial strain over their involvement in the performance of nightshift duty at the University of Lagos library.
