Extended mass layoff events in 2000 were concentrated at the lower end of the size spectrum, with 58 percent involving fewer than 150 workers.
Although nearly 3 of every 5 layoffs involved 150 employees or fewer, they accounted for only 25 percent of all separated workers. Layoffs involving 500 or more workers, just 7 percent of all events, accounted for 34 percent of all separations.
There was an average of 208 separations per extended mass layoff event in 2000.
