Zero Wisconsin businesses filed layoff notices in June, the first month without any such reports in three years after four companies reported 311 affected workers in May.
The drop came as Wisconsin's unemployment rate edged down to 3.4% in May, with the number of unemployed falling by 16,000 to 89,600 on a non-seasonally adjusted basis.
Manufacturing, mining, logging and construction added about 5,100 jobs in May, helping lift overall state employment by more than 4,000 from April and 5,800 from a year earlier.
Layoff notices still understate job cuts because filings are required only in larger events; Harley-Davidson in March and Molson Coors last October cut workers without filing notices.
