PurposeThe purpose of this paper is to examine the career shocks of Red Cross (RC) of Serbia staff and volunteers providing aid during the 2016 migrants’ influx. Specifically, the authors explore what the volatile environment in which RC staff and volunteers work can teach us about career shocks, and what makes a career shock for people whose everyday work entails stressful events.Design/methodology/approachThis study examined a number of anecdotes that reflect the career shock construct to a greater or lesser extent. These anecdotes were developed by RC staff and volunteers as part of a communications training storytelling exercise.FindingsThe authors analyzed these events from the perspective of recent developments in career shocks research and examined whether the anecdotes contained elements that would enable us to differentiate between career shocks and stressors. Those anecdotes found to be the most prototypical of career shocks, as opposed to stressors, were found to instigate in-depth reflection about the career, were identity related, and had a tangible career impact. Shocking events in the eyes of RC people entailed work demands that go beyond expectations, excessive media scrutiny, and conflicting values. The authors discuss how organizational values, fostering person–organization fit, providing organizational and collegial support, and deploying “weathered” staff, could comprise the “vaccine” that makes the organization immune to career shocks.Originality/valueBy taking a data before theory approach to the study of career shocks, this paper provides a novel perspective on the lived experiences of RC people, and how such experiences may be classified into career shocks or stressors.
