Bread could be in short supply in Israel within a few weeks. The Histradrut labor union announced Sunday that workers at Angel Bakeries, the country’s largest producer of bread, had declared a work dispute. The two sides will now enter binding arbitration on their disagreements. If the issues are not resolved within two weeks, the union has a right to declare a strike under Israeli labor laws.

The union received permission to declare the work dispute Sunday from the Jerusalem District Labor Court. The union told the court that it had been seeking to negotiate a new contract for workers since May, when the old one ran out, but that management had “dragged out the proceedings for months, indicating that their entire purpose is not to conclude a labor agreement, but to avoid concluding one.” Union representatives added that management was seeking to take back concessions made in the past.

A union official said Sunday that if management did not begin negotiating in good faith, “we will not hesitate to close the bakery.”

In yet another labor issue, the Histadrut also declared a work dispute on behalf of 2,200 workers at Ness Technologies, one of the few high-tech companies in Israel where workers are unionized. The union accused management of making unauthorized changes to workers’ contracts, and of failing to negotiate in good faith on new contracts.

Neither Angel Bakery nor Ness management had any comments on the respective disputes.
