WASHINGTON (AP) — U.S. job openings fell slightly in June, but the labor market continued to show resilience in the face of an economic shock from fighting in Iran and the closure of the Strait of Hormuz. Employers posted 7.36 million vacancies in June, down from 7.54 million in May, the Labor Department said Tuesday. Openings rose by 97,000 at warehouse, transportation and utility companies and 39,000 at federal government agencies. The gross number of people hired — before subtracting those who quit or lost their jobs — rose slightly 5.3 million. Before the war in Iran, roughly 15 million barrels of Persian Gulf oil were shipped each day through the Strait of Hormuz.
