Union Effects in Low-Wage Services: Evidence from Canadian Childcare
Bibliographic record
Abstract
Empirical evidence presented in this paper, based on survey data for Canadian childcare workers in 1991, contradicts most stereotypes of the childcare labor market. Although childcare labor was low-wage, the authors find that the union impact on wages (15%) and fringe benefits was in line with union effects found in other, better-compensated work, and they find substantial returns to education, occupational level, and firm-specific experience. The returns to the skill-related attributes were blunted somewhat in the union sector, except where such returns stood to benefit the median union voter. The findings suggest that monetary incentives can be used to encourage improvements in the education, experience, and skill acquisition of childcare workers. Unions can improve wages and benefits for childcare workers just as they can for most other workers, suggesting the viability of union organizing in this sector despite the traditional barriers to organizing low-wage service sector workers in small firms.

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.
