“We are invisible to society”: impacts of working conditions on food delivery workers’ health and quality of life during the COVID-19 pandemic
Bibliographic record
Abstract
Abstract The COVID-19 pandemic aggravated the scenario of low income, hunger, unemployment, and informality generated by the 2017 Labor Reform and the dismantling of social policies, leading many workers to enter the food delivery business that misses labor rights or protection. Thus, this study aimed at investigating how such working conditions impacted food delivery workers’ health and quality of life in Curitiba, Brazil, during the pandemic according to delivery categories. Field research, based on saturation of discourse, was conducted in 10 delivery points using a semi-structured instrument. Despite mentioning several negative aspects regarding working conditions, most delivery workers perceived a positive quality of life, mainly associated with the possibility of work and financial return. App-based delivery workers felt more intensely the negative impacts on health and quality of life. These findings point to the need for further discussions on how these new contemporary and precarious labor arrangements impact occupational health in different contexts and categories.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
