Abstract: | A contemporary issue of major concern is the millions of people fleeing homelands owing to political and socioeconomic challenges and seeking assistance elsewhere throughout the world. An effective response to this crisis includes support models that meet the various needs of refugee populations. In the complex system of humanitarian action, aid workers, among a multiplicity of actors, are the most important assets. This study utilised an inclusion–exclusion theoretical lens to examine the impact of their workplace experiences on activities in the context of the refugee crisis in Lebanon. In-depth interviews were held with 36 humanitarian practitioners, representing five international organisations that are involved in refugee aid programmes in the country. The study led to a new understanding of the link between inclusion and exclusion and the effectiveness of the humanitarian response to emergencies. In addition, it yielded new insights into apprehension about the national–international divide and its consequences for humanitarian assistance. |
