Haifa, Israel-Another work dispute may be in the offing at Haifa Chemicals, the world’s largest producer of potassium nitrate. The company’s management is refusing to pay for the six-day lockout three weeks ago (GM March 28, 2011). The management charges that the strike by workers caused damage to the Haifa production plant that led to a forced shutdown in order to repair the facility. Some 250 workers are affected by the management move, and they are threatening to impose sanctions unless they are paid for the six-day shutdown.
