Déclin et renouvellement de la main-d'oeuvre industrielle

De
17 pages
De 1975 jusque dans les années 90, la réduction des effectifs ouvriers s'est portée d'abord sur les plus jeunes par la diminution des recrutements, puis sur les anciens par les départs en retraite ou préretraite de plus en plus précoce. Cette réduction a aussi eu pour effet de modeler la structure d'âge de la main d'oeuvre, la centrant sur les âges intermédiaires. Les structures d'âge, telles qu'elles se présentaient il y a dix ou quinze ans dans les différents secteurs, permettaient de faire façe à certaines contraintes de travail par leur répartition différenciée selon les âges. Ces formes de sélection sur l'âge sont désormais remises en question. L'analyse des structures d'âge et de leur évolution conforte donc la nécessité de s'attaquer à la conception et à l'aménagement des moyens de travail, aux conditions et à l'organisation du travail pour pallier les effets du viellissement en cours de la population ouvrière.

the workforce’s age structure, centring it on the intermediate ages.
The age structures found in the different sectors ten to fifteen years ago helped
overcome certain working constraints by means of their different age
breakdowns. These forms of age-based selection are now being challenged.
An analysis of age structures and their evolution upholds the need to address the
design and development of ways of working, working conditions and job
engineering to offset the effects of the current ageing of the manual employee
