Prism of Labour: Unsettling Knowledge, Skill, and Technology in Work Infrastructures
This is a strong CHI honorable-mention paper because it does more than document migrant farm labor: it reframes skill as something actively produced through classification and infrastructure. The prism of labour is the paper’s real contribution, giving the field a vocabulary for analyzing and intervening in how expertise is reorganized across sites.

Review Summary
This paper’s strongest contribution is conceptual rather than technical in the narrow sense. It takes a familiar HCI concern—how technologies shape work—and sharpens it into a more precise account of how labor infrastructures are assembled through the interaction of knowledge practices, skill labels, and sociotechnical control. The departure from common sense is clear: the workers are not simply “skilled” or “unskilled” by inherent ability, but are reclassified across contexts, with surveillance and managerial systems helping stabilize that reclassification. That is a useful corrective to any account that treats skill as portable, neutral, or self-evident. The novelty lies in the prism of labour, which the authors present as both an analytic and intervention tool. In the evidence provided, the prism is not just a metaphor; it is meant to trace relations among knowledge practices, skill classifications, and sociotechnical systems in order to understand how labor infrastructures are formed, stabilized, and contested. That makes the contribution legible as a framework or synthesis contribution, with normative force as well as descriptive insight. The empirical base is a multi-sited critical ethnography following five Mexican men between farms in Oaxaca and Veracruz and greenhouses in Ontario during 2022–2023. That scope is appropriate for the kind of interpretive claim being made, but it also means the paper is not offering broad statistical generalization or a system benchmark. The authors are appropriately explicit about limits: the sample is small, the study does not claim to capture the full range of migrant greenhouse worker experiences, and the prism’s transferability beyond transnational agricultural work is still open. Those limitations matter, but they do not undercut the paper’s value; they instead clarify the boundary conditions under which the framework should be read. Overall, this is a well-grounded CHI honorable-mention contribution that advances critical labor scholarship by giving researchers a sharper lens for understanding how expertise is reorganized through migration and infrastructure.
What Changed
Canon before
Prior HCI work on labor, migration, and agricultural technology has often treated skill as a stable attribute or focused on technology adoption without centering how classification systems and infrastructures re-make expertise across contexts.
Departure from common sense
The paper’s core move is to show that skill is not simply carried intact across borders; the same workers can be treated as skilled in one setting and unskilled in another, with surveillance and managerial systems helping produce that reclassification rather than merely recording it.
Actual novelty
The paper introduces the prism of labour as an analytic and intervention tool for tracing how knowledge practices, skill classifications, and sociotechnical systems interrelate to form labour infrastructures. That framing is the paper’s main conceptual contribution beyond the empirical case.
Evidence
The paper grounds its claims in a multi-sited critical ethnography following five Mexican men between farms in Oaxaca and Veracruz and greenhouses in Ontario during 2022–2023. The abstract and study description support both the empirical scope and the conceptual move to the prism of labour. The authors also explicitly note limits: small sample size, incomplete capture of worker experiences, and untested transferability beyond transnational agricultural work.

Limits
Method limits
The study is based on a small sample and a multi-sited ethnography, so it supports interpretive and conceptual claims rather than broad causal generalization. The authors also state that they do not capture the full range of migrant greenhouse worker experiences.
Deployment limits
The prism of labour is presented as an analytic and intervention lens, but the authors note it is untested beyond this case. Its use outside transnational agricultural work remains open.
Boundary conditions
The findings are bounded by transnational agricultural labor, specifically Mexican migrant workers moving between smallholder farms in Mexico and high-tech greenhouses in Canada. Uneven access in Canada also shapes what could be directly observed.
Position in field
This sits in the CHI tradition of critical labor and infrastructure studies, but pushes beyond descriptive accounts of migrant work by theorizing how classification, expertise, and sociotechnical systems co-produce labor infrastructures.
