This article investigates whether collective disputes and individual disputes are substitutes in French workplaces. Using a nationally representative dataset, this article focuses on two prominent and distinct individual disputes in France, that is, employee applications to Employment Tribunals and employer disciplinary action, and considers alternately strikes and non-strike disputes at the collective level. Our results suggest that collective disputes, with or without a strike, are substitutes only for Employment Tribunal claims, due to a significant negative relationship between them. In contrast, collective disputes are found to heighten disciplinary action in French workplaces.
