In a major development in the law on workers' rights to unionize, the National Labor Court has ruled that employers cannot interfere, directly or indirectly, with employees' initial attempts to organize. Wednesday's ruling came in a complaint filed by the Histadrut labor federation against Pelephone, which has refused to recognize a workers' local organized through the Histadrut. The cellular service provider claims that not enough employees have signed on as union members to give the local official status. A panel of judges…said that Pelephone, a Bezeq subsidiary, must not try to foil organizing efforts or influence the workers' decision on joining the union. The court also barred employers from taking any action that might curb workers' right to organize…Pelephone' stance is that it recognizes the right of workers to organize, but says employers also have the constitutional right to freedom of expression, which includes the right to express opposition to the workers' moves.
