CLERMONT-FERRAND, France (Jan. 23)—Groupe Michelin has postponed its work force referendum on the company´s proposals for the introduction of a 35-hour workweek, on the orders of a Clermont-Ferrand court. Michelin´s 27,000 employees in France were scheduled to vote Jan. 25. The local court ruling Jan. 19 said Michelin must wait for a verdict from a higher court—the Tribunal de Grande Instance—on a legal challenge to the referendum by the CGT trade union. This decision is expected by Jan. 24. Michelin deeply regrets the CGT´s attempt to prevent the referendum and interfere with the ability of employees to give their opinion on the proposals, said Francois d´Avout, Michelin personnel director.
