Farmers are automating care of animals and their habitats, for instance, by predicting and automating feeding. But how does workplace automation influence agrifood workers’ experienced responsibilities for animals and their environment (‘environmental care practices’). Qualitative research at two high-tech fish farms will answer this question, with the aim of establishing an innovative, interdisciplinary research line in work organisation research. The ground-breaking aspect is that fish farms potentially make visible the effects of automation on relations between workers, animals and habitats, instead of focusing on human autonomy. The results can support technology design and contribute to policy debates about farming reforms.
