US: 25 drivers and mechanics at Island Ready-Mix Concrete’s Kapolei ready-mix concrete batching plant in Hawaii went on strike on 23 July 2025. Hawaii News Now has reported that workers at the 500m3/day plant are demanding two days off per seven-day working week. The parties have held 16 rounds of negotiations, with the next upcoming session scheduled for 18 August 2025, when workers are expected to respond to the company’s offer of a 14% wage rise over a period of three years. Both parties have already ‘tentatively’ accepted 15 provisions of an agreement.
