PurposeThis paper argues that accent modification acts as a mechanism that (re)produces workplace accentism, which is a set of ideologies and practices positioning some English accents as inherently superior/inferior to others in the context of work and careers.Design/methodology/approachThis conceptual paper draws on existing literature mainly from critical sociolinguistic and labor studies to support its central argument.FindingsThrough acting as a skill, a technology and a commodified service, accent modification naturalizes linguistic hierarchies, which are racist, classist and colonial constructions, and reinforces the structural status quo in different contexts.Practical implicationsIn order to move away from accent modification as a means to enhance oral communication at work, organizational attempts at fostering mutual intelligibility and undoing the role of accent in workplace communication are necessary.Originality/valueContrary to research that presents accentism as a purely interpersonal issue, the paper explores how accentism is institutionalized and is connected to linguistic profiling.
