Réduction du temps de travail et emploi : quelques leçons du passage aux 39 heures de 1982

[fre] Nous utilisons des données longitudinales sur l'emploi, les salaires et les heures de travail afin d'examiner les effets de la réduction obligatoire de la durée du travail hebdomadaire intervenue en 1981 en France. Quelques mois après l'élection de François Mitterrand en mai 1981, le gouvernement, en application de son programme, décida tout d'abord d'augmenter le salaire minimum de 5 %, puis de réduire la durée hebdomadaire du travail — tout en maintenant, et ceci de manière obligatoire, la rémunération mensuelle des travailleurs payés au salaire minimum et en recommandant fortement la stabilité des gains mensuels pour les autres travailleurs (recommandation suivie d'effets pour 90 % des entreprises). Nous montrons que les travailleurs directement affectés par ces changements, c'est-à-dire ceux travaillant 40 heures en mars 1981, ont perdu leur emploi entre 1981 et 1983 plus souvent que les travailleurs non affectés directement par ces changements, c'est-à-dire ceux tra- vaillant 39 heures en mars 1981 ; la probabilité de perdre son emploi passant de 10 % à 12,5 % pour les premiers. En outre, les travailleurs affectés à la fois par les changements du salaire minimum et la réduction de la durée hebdomadaire de travail ont été encore plus durablement touchés ; leur taux de transition emploi- non emploi a crû de 10 % à 23 %. Ces résultats devraient nous permettre de comprendre les effets possibles de la réduction de la durée hebdomadaire de travail à venir — durée passant de 39 à 35 heures — en l'an 2000 en France. Des projets similaires sont à l'étude dans d'autres pays européens dans l'espoir que de telles mesures de réduction forcée des heures permettront de lutter efficacement contre le chômage. [eng] We use longitudinal individual wage, hours, and employment data to investigate the effect of the 1981 mandatory reduction of weekly working hours in France. A few months after François Mitterrand's election of May 1981, the government, applying its programme decided first to increase the minimum wage by 5% and, second, to reduce weekly working hours — from 40 to 39 — together with mandatory stability of monthly earnings of minimum wage workers and strong recommendation for stability of monthly earnings for other workers (indeed, followed by 90% of the firms). We show that workers directly affected by these changes, those working 40 hours in March 1981, lost their jobs between 1981 and 1983 more often than workers not affected by the changes, those working 39 hours in March 1981; their year-to-year job loss probability increased from roughly 10% to 12.5%. Moreover, workers affected by both minimum wage changes and hours reduction were even more strongly hit ; their year-to-year job loss probability increased from roughly 10% to 23%. These results should help us understand the possible effects of the forthcoming mandatory reduction of hours in France, the weekly working hours going from 39 to 35 hours in year 2000. Similar projects are envisaged in other European countries hoping that hours reduction are an efficient way of tackling their unemployment problem.
