The introduction of “International Perspectives on Language and Work: Analysing the Impact of Mutual Influences” sets foundational elements of this specific encounter in the field, between the sociology of work and the sociology of language, from the perspective of looking at language rather than solely through it. After a presentation of how language and work intersect in today’s dynamic language-labour landscape, it addresses the evolving nature of labour markets due to economic and geopolitical challenges, emphasising the importance of understanding how language shapes work environments, and how language in return is processed too. The aim is to bridge the sociology of language and the sociology of work, examining how language influences organisational dynamics, professionalisation processes, new forms of work and employment and power relations. International perspectives support the elucidation of the reciprocal impacts of language and work across various contexts: case studies from four continents and with quotations in the original language as with an English translation are briefly presented to outline the thematic contributions of each chapter.
