The number of workers involved totaled 87,501. The manufacturing sector continued to represent a large portion of those mass layoffs, accounting for 22% of all mass layoff events and 25% of all initial claims filed in May, according to data released June 23. A year ago manufacturing represented 29% of all events and 35% of initial claims. Within the manufacturing sector, the number of claimants was highest in food processing, transportation equipment and textile product mills.
