" The European Union Energy Sector Directive no. 96/62 laid down that Member States were to initiate a market liberalisation process in the electricity sector. In this context Pacts for Employment and Competitiveness (PEC) represent part of a strategy enterprises are adopting in order to face the challenge of managing the changeover from near-monopoly to internationally competitive structures. The article, based on ten case studies carried out in five EU Member States, looks at the thinking underlying these pacts, the changes at the level of collective bargaining, and how the PECs are interpreted by the parties involved: not only the contents of the PECs, but also the underlying motives, the processes of negotiation and the effects of the agreements. It points to areas in which PECs have been able to contribute to generating win-win situations, but also to possible ambiguities and contradictions linked to the negotiation and implementation of such pacts.

"Le réseau d'énergie (lignes, câbles, postes de transformation) transporte, répartit et distribue l'énergie fournie par les centrales à tous les utilisateurs. Le passage de l'électricité dans les lignes de transmission haute tension et des postes de transformation génère, dans leur voisinage immédiat, des champs électriques et magnétiques. Cette fiche traite de l'exposition professionnelle aux champs électriques ou magnétiques à la fréquence de 50 Hz (hertz). Cette fréquence fait partie de la gamme des ELF(extremely low frequencies,1 Hz à 10k Hz)."

"The main aim of this study was the analysis of occupational lung cancer risk factors in the French national electricity and gas company (Electricite de France-Gaz de France (EDF-GDF)). A case-control survey nested in a cohort of male employees was undertaken. The study population consisted of all male staff who were active at EDF-GDF between January 1, 1978, and December 31, 1989. During this period, 310 cases of lung cancer were identified in the cancer register set up by the medical department of the company. For each case, four agematched controls who were free of cancer at the time of occurrence of the case's lung cancer were randomly selected. Occupational exposures to 21 chemical agents were assessed for each subject using a job exposure matrix. The associations between lung cancer and the different agents were estimated using conditional logistic regression analysis. After adjustment for various occupational confounding factors, the analysis showed increased lung cancer risks linked to exposure to crystalline silica (highest exposure class: odds ratio = 2.27; 95% confidence interval: 1.10, 4.68) and creosotes (highest exposure level: odds ratio = 2.14; 95% confidence interval: 1.06, 4.31), with significant dose-response relationships for both exposures."
