The Impact of Anti-Temporary Replacement Legislation on Work Stoppages: Empirical Evidence from Canada
Bibliographic record
Abstract
Legislation that prevents the hiring of temporary replacement workers during a work stoppage is controversial. “Anti-temporary replacement worker” legislation (ATR) or “anti-scab” legislation is currently in effect in Quebec and British Columbia and existed for a short period of time in Ontario. This paper uses variation over time (1978–2003) and across provinces to provide empirical evidence concerning the impact of ATR on work stoppages. The results show that ATR increases strike incidence and decreases strike length—both effects are statistically significant and substantial in magnitude. Incidence and length have opposing effects on days lost to work stoppages. Empirical results provide weak evidence that anti-scab legislation may increase days lost to work stoppages in the first two years after the legislation takes effect but no evidence that such legislation has a statistically significant effect on days lost when it has been in effect for more than two years.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
