For all of 2011, employers reported 6,331 extended mass layoff actions, affecting 1,045,220 workers. Compared to 2010, the number of events decreased by 916 (13 percent) and the number of separations decreased 211,914 (17 percent).
Permanent worksite closures accounted for 8 percent of extended mass layoff events in 2011, the lowest proportion of events due to closure in program history (with annual data available back to 1996).
Among the seven categories of economic reasons for layoff, layoffs due to business demand factors accounted for the largest number of events during 2011 (2,268), largely due to contract completion. Layoffs attributed to this reason occurred primarily in construction and in administrative and waste services, which includes temporary help services.
In addition to business demand factors, seasonal factors accounted for the second largest number of layoff events during 2011 (2,188), followed by layoff events due to other/miscellaneous reasons (1,055), financial issues (401), and organizational changes (299).
