Arbeitszeitflexibilisierung in der westdeutschen Metall- und Elektroindustrie und die Verbandsstrategien - Eine vergleichende Analyse der arbeitszeitpolitischen Strategien des Arbeitgeberverbandes Gesamtmetall und der Industriegewerkschaft Metall

Arbeitszeitpolitik und Arbeitszeitgestaltung haben seit dem Tarifkompromiss im Jahre 1984 in der Metall-, und Elektroindustrie in der politischen und wissenschaftlichen Diskussion einen immensen Bedeutungszuwachs erfahren. Die Forderungen nach einer flexibleren Arbeitszeitgestaltung haben zeitgleich sowohl aus der Globalisierungsdiskussion und der Debatte um die Wettbewerbsfähigkeit des "Wirtschaftsstandorts Deutschland" heraus wie auch aus beschäftigungspolitischen Gründen neuen Auftrieb bekommen. Die Diskussion um die Arbeitszeit ist gleichzeitig von verschiedenen, meist gegensätzlichen Interessen geprägt: Auf der Beschäftigtenseite zielt die Arbeitszeitflexibilisierung nach wie vor auf Zeitsouveränität: d.h. auf eine bessere Vereinbarkeit der Arbeitszeit mit allen Aktivitäten außerhalb der Arbeitszeit ab. Demgegenüber stellt die Arbeitgeberseite den betriebswirtschaftlichen Aspekt in den Vordergrund. D.h. die Anpassung der Arbeitszeit an den tatsächlichen Arbeitsanfall. So soll durch aufeinander abgestimmte Gestaltung von Betriebszeit und Arbeitszeit die Erhöhung der Produktivität und die Sicherung der Wettbewerbsfähigkeit erzielt werden. Durch diesen Trend verlor das sog. Normalarbeitsverhältnis an Allgemeingültigkeit und die Flexibilisierung der Arbeitszeiten nahm seit langem kontinuierlich zu. Folge ist, dass mittlerweile eine breite Palette von Arbeitszeitmodellen existiert, in denen die gesetzlich und vertraglich vereinbarte Wochenarbeitszeit in den Dimensionen Lage, Länge und Verteilung flexibilisiert wird. Auch die Tarifverhandlungen und Auseinandersetzung der Tarifparteien zur Arbeitszeitpolitik sind dadurch gekennzeichnet, dass die Arbeitszeitflexibilisierung und Verlagerung der Tarifpolitik auf betriebliche Ebene einen Bedeutungszuwachs bekam und die Meinungsführerschaft in Sachen Arbeitszeitgestaltung von der IG Metall zu Gesamtmetall wechselte. Ziel der vorliegenden Dissertation war es, anhand einer empirisch-historischen Untersuchung über Einstellungen sowie Strategien von Gesamtmetall und IG Metall die Gestaltungsspielräume flexibler Arbeitszeitmodelle zu bestimmen und gleichzeitig die Defizite herauszuarbeiten. Die Untersuchung gründete sich in erster Linie auf die Dokumentenanalyse von Stellungnahmen der Gesamtmetall und IG-Metall-Leitungsgremien sowie Primär- und Sekundäranalyse von Befragungen der Beschäftigten. Die leitende Frage der Untersuchung war, ob es den Arbeitgeberverbänden und den Gewerkschaften gelingen konnte, die Erfordernisse eines Betriebes und die Belange der Beschäftigten weitgehend in Übereinstimmung zu bringen? Und (wenn ja) unter welchen Voraussetzungen die neuen flexiblen Arbeitszeitsysteme mit den betrieblichen und außerbetrieblichen Interessen der Beschäftigten zu vereinbaren sind. Den Hintergrund für diese Zielerreichung bildete der gesellschaftliche Konflikt zwischen Arbeit und Kapital. Denn die Schwierigkeit bzw. Komplexität lag in der Frage, wie die unterschiedlichen Interessen, die sich in der industriekapitalistischen Gesellschaft durch den Gegensatz "Kapital" und "Arbeit" bestimmen lassen, zu vereinbaren waren bzw. sind.

Berufsanforderungen und flexible Altersgrenze

In 1973 the government of the Federal Republic plans to introduce a flexible retirement age. According to this new law, old age pensions can be paid already to people who are 63 years of age instead of 65 as at present. The government thus hopes to do more justice to the difference in capacity for work of elderly insured people and to the lact that the decline of life of humans depends to a certain extent on the occupational requirements demanded of them. Based on social science and medical research results this essay shows that the flexible retirement age cannot master these problems. The essay mentions in particular general relationships between age and work as well as special relationships between practised work, illness, disability and age. The bibliography includes literature connected with other aspects of the flexible retirement age.

The Containment of Labour Unrest in the Post Socialist China

Due to its transition from the socialist mode of production to the capitalist mode, workers in China have been exposed to the exploitative class relations that they hardly experienced before. The working class is now assuming a subordinate position in the relations of production while the capitalist class remains in the dominant position. As a consequence, workers’ protests are constantly emerging and class conflicts are exacerbating in the contemporary China. I have set out to study in this paper how the party-state in China contains labour unrest through the All China Federation of Trade Unions (the ACFTU), which I argue is a state apparatus that performs the ideological, political and economic functions in different situations. There has been an ongoing academic debate on if the ACFTU is defending workers’ interests. Some scholars have expressed optimism while some have taken a dim view. Drawing on Poulantzas’ theory of capitalist state, I hope to make contribution to this debate by demonstrating that the ACFTU is under some circumstances serving the short term interests of workers as individuals, but not the economic and political interests of workers as a class. Instead of organizing workers to overcome the effects of isolation or forming a class for itself, the ACFTU attempts to contain labour unrest and reproduce their subordination in the relations of production.

Reciprocal and wage labour in rural Ecuador. A quantitative analysis

This paper analyses the determinants for rural Ecuadorian households to participate in community works, to exchange labour, and to use paid labour. The results show that participation in community work is more common among indigenous peoples who are more committed with community and live in areas with relatively high population densities. Exchange labour agreements are more common among indigenous households settled in areas where industrial agriculture has not penetrated yet. Instead, paid labour is used by small and educated households which have access to credit.

Design and Implementation of a Flexible Robot

This robot has low natural frequencies of vibration. Insights into the problems of designing joint and link flexibility are discussed. The robot has three flexible rotary actuators and two flexible, interchangeable links, and is controlled by three independent processors on a VMEbus. Results from experiments on the control of residual vibration for different types of robot motion are presented. Impulse prefiltering and slowly accelerating moves are compared and shown to be effective at reducing residual vibration.

European employment strategy and spanish labour market policies

The paper aim is to analyse the influence of the European Employment Strategy (EES)in the implementation of the Spanish labour market policies. The first part of the paper describes the evolution and content of the EES. In the second one, the definition of activation is also explained. In addition to that, the ways how the EES develops and promotes active labour market policies are examined. The evolution of labour market policies in Spain and the current configuration of both active and passive policies are studied in the next three chapters. In these parts, the paper investigates to which extent the provisions of the EES have been implemented in Spain. The paper shows that: i) activation has been rising in the European countries since the implementation of the EES; ii) this fact has also happened in relative terms (comparing the evolution of active to passive policies); iii) Spain has been one of the countries which has led these processes; iv) the EES seems to have been influencing

Agrupamiento flexible de alumnos en la Educación Primaria : una respuesta a la diversidad.

Verificar la eficacia de una experiencia de innovación sobre agrupamiento flexible de alumnos en una estructura multinivel; focalizando el problema en la necesidad de responder a la diversidad existente en cada aula,diseñando, frente a la organización tradicional graduada, una nueva estructura organizativa que establece tres modalidades distintas de agrupamiento: multinivel propiamente dicho, para las Áreas de Lengua y Matemáticas; graduado para el resto de las áreas, y flexible según tareas; se contempla, así mismo una organización también flexible de profesores y una adaptación del curriculum escolar a dicha estructura.. Son objeto de investigación todos los alumnos de Primer Ciclo de Educación Primaria del CP de Las Vegas en Corvera de Asturias.. Tras la exposición del marco teórico sobre el que gira la experiencia de innovación (curriculum escolar y organización de la enseñanza) se hace una descripción del proceso de planificación y puesta en práctica de la nueva estructura organizativa y se analiza su incidencia sobre los alumnos implicados, en relación con su actitud ante la enseñanza y con su rendimiento académico.. Escalas, registros, entrevistas, diario de investigación, grabaciones de las clases, encuestas, cuestionarios, etc.. Análisis cualitativo de los registros observacionales, de los resultados de las entrevistas, del contenido del diario de investigación, de las producciones de los alumnos; porcentajes de rendimiento académico, de movilidad internivelar de los alumnos.. El análisis de los datos confirma los efectos positivos de la estructura multinivel sobre la actitud y rendimiento de los alumnos al permitir que cada uno, respetando sus condiciones de partida, progrese de acuerdo a su capacidad y a su ritmo de aprendizaje. El planteamiento cooperativo del trabajo docente permitió que los profesores mejorarán su práctica y dispusieran de un mayor control, sobre sus actividades, incrementando su desarrollo profesional.. La estructura multinivel constituye una buena alternativa al problema de atención a la diversidad al introducir elementos de mayor racionalidad y flexibilidad en el funcionamiento de los centros docentes. La rigidez de la estructura organizativa graduada y la enseñanza homogénea y uniforme que produce, apoyada básicamente en los libros de texto estandarizados, dificulta un tratamiento educativo más individualizado y la aplicación práctica de la teoría del progreso continuo..

The allometry of non-employment. What can compositional data analysis tell us about labour market performance across the UK's regions?

The low levels of unemployment recorded in the UK in recent years are widely cited as evidence of the country’s improved economic performance, and the apparent convergence of unemployment rates across the country’s regions used to suggest that the longstanding divide in living standards between the relatively prosperous ‘south’ and the more depressed ‘north’ has been substantially narrowed. Dissenters from these conclusions have drawn attention to the greatly increased extent of non-employment (around a quarter of the UK’s working age population are not in employment) and the marked regional dimension in its distribution across the country. Amongst these dissenters it is generally agreed that non-employment is concentrated amongst older males previously employed in the now very much smaller ‘heavy’ industries (e.g. coal, steel, shipbuilding). This paper uses the tools of compositiona l data analysis to provide a much richer picture of non-employment and one which challenges the conventional analysis wisdom about UK labour market performance as well as the dissenters view of the nature of the problem. It is shown that, associated with the striking ‘north/south’ divide in nonemployment rates, there is a statistically significant relationship between the size of the non-employment rate and the composition of non-employment. Specifically, it is shown that the share of unemployment in non-employment is negatively correlated with the overall non-employment rate: in regions where the non-employment rate is high the share of unemployment is relatively low. So the unemployment rate is not a very reliable indicator of regional disparities in labour market performance. Even more importantly from a policy viewpoint, a significant positive relationship is found between the size of the non-employment rate and the share of those not employed through reason of sickness or disability and it seems (contrary to the dissenters) that this connection is just as strong for women as it is for men

Decentralized model reference control of flexible cable-stayed beam structures

A decentralized model reference controller is designed to reduce the magnitude of the transversal vibration of a flexible cable-stayed beam structure induced by a seismic excitation. The controller design is made based on the principle of sliding mode such that a priori knowledge

A mixed H2/H∞-based semiactive control for vibration mitigation in flexible structures

In this paper, we address this problem through the design of a semiactive controller based on the mixed H2/H∞ control theory. The vibrations caused by the seismic motions are mitigated by a semiactive damper installed in the bottom of the structure. It is meant by semiactive damper, a device that absorbs but cannot inject energy into the system. Sufficient conditions for the design of a desired control are given in terms of linear matrix inequalities (LMIs). A controller that guarantees asymptotic stability and a mixed H2/H∞ performance is then developed. An algorithm is proposed to handle the semiactive nature of the actuator. The performance of the controller is experimentally evaluated in a real-time hybrid testing facility that consists of a physical specimen (a small-scale magnetorheological damper) and a numerical model (a large-scale three-story building)

El Proyecto Campus Extens y la iniciativa Xarxipèlag de la Conselleria d'Educació constituyen respuestas a esta tendencia. Se analiza la introducción de estas cuestiones en la ciudadanía, la enseñanza obligatoria y el ámbito universitario.

The Ergonomic Analysis and Back Injuries in Flexible Production System

Back injuries identification and diagnoses in the transition of the Taylor model to the flexiblemodel of production organization, demands a parallel intervention of prevention actors at work. This study uses simultaneously three intervention models (structured action analysis, muscle skeletal symptoms questionnaires and muscle skeletal assessment) for work activities in a packaging plant. In this study seventy and two (72) operative workers participated (28 workers with muscle skeletal evaluation). In an intervention period of 10 months, the physical, cognitive, organizational components and productive process dynamics were evaluated from the muscle skeletal demands issues. The differences established between objective exposure at risk, back injury risk perception, appreciation and a vertebral spine evaluation, in prior and post intervention, determines the structure for a muscle skeletal risk management system. This study explains that back injury symptoms can be more efficiently reduced among operative workers combining measures registered and the adjustment between dynamics, the changes at work and efficient gestures development. Relevance: the results of this study can be used to pre ent back injuries in workers of flexible production processes.
