This workshop introduces the design process and core mechanics of a mobile digital game developed for workplace-situated language learning (https://workdplays.com). Originally created for migrant workers in Danish slaughterhouses, the platform has since been expanded to support additional labor industries with high proportions of migrant employees, as well as multiple target languages. A key challenge in workplace integration for many migrant workers lies in persistent communication barriers, particularly in contexts where formal language education is inaccessible or insufficient for highly task-specific communicative needs. Drawing on principles from serious games, the game simulates authentic workplace interactions within a safe, scaffolded digital environment. During the workshop, participants will explore the game firsthand and examine how ethnographically informed design decisions are operationalized through concrete gameplay mechanics. The workshop will also present findings from quantitative analyses conducted at multiple factory sites in Denmark, which demonstrate measurable improvements in learners’ acquisition of workplace-relevant Danish vocabulary following gameplay. By combining hands-on exploration with discussion of design rationale and learning outcomes, the workshop provides practical insights into how mobile, game-based platforms can be designed and adapted to support language learning in real-world workplace contexts.
