                                        MAJOR WORK STOPPAGES IN 2011


     In 2011, there were 19 major strikes and lockouts involving 1,000 or more workers and lasting at least 
one shift, the U.S. Bureau of Labor Statistics reported today.  The 19 major work stoppages in 2011 
idled 113,000 workers for 1.02 million lost workdays, a large increase compared to 2010 with 11 major 
work stoppage idling 45,000 workers for 302,000 lost workdays. In 2009, there were record lows of 5 
major work stoppages idling 13,000 workers for 124,000 lost workdays. (See table 1.)

     The longest work stoppage beginning in 2011 was between American Crystal Sugar Company and the 
Bakery, Confectionary, Tobacco Workers and Grain Millers, Sugar Council.  The ongoing work stoppage 
began in August and has lasted throughout the remainder of 2011 (105 workdays) with 1,300 workers 
accounting for 136,500 lost workdays. The largest work stoppage in 2011 in terms of number of workers 
and total workdays idle was between Verizon Communications and the Communications Workers of 
America and the International Brotherhood of Electrical Workers, with 45,000 workers accounting for 
450,000 lost workdays. (See table 2.)

     This release includes information for the work stoppage between the National Football League (NFL) 
and the NFL Players Association. The work stoppage between the National Basketball Association 
(NBA) and the NBA Players Association involved fewer than 1,000 workers and is therefore not part of 
this data series. 



                                            TECHNICAL NOTE

     The major work stoppages series dates back to 1947.  The term “major work stoppage” includes both 
worker-initiated strikes and employer-initiated lockouts that involve 1,000 workers or more and lasting 
at least one shift.  BLS does not distinguish between lockouts and strikes in its statistics.

     Information on work stoppages is obtained from reports from the Federal Mediation and Conciliation 
Service, State labor market information offices, BLS Strike Reports from the Office of Employment and 
Unemployment Statistics, and from major media sources.  One or both parties involved in the work 
stoppage (employer or union) is contacted to verify the duration and number of workers idled by the 
stoppage. 

     Days of idleness is calculated by multiplying the number of workers involved in the strike or lockout by 
the number of days workers are off the job.  The number of working days lost for every major work 
stoppage is based on a 5-day workweek (Monday through Friday), excluding Federal holidays.  

Monthly major work stoppages data

     The Bureau of Labor Statistics compiles detailed monthly statistics on major work stoppages at 
http://www.bls.gov/wsp.  

     Detailed data for each major work stoppage since 1993 includes the organization involved, location, 
beginning and ending work stoppage dates, the number of workers, and days idle.  

     Monthly time series data since 1981 have been published (http://data.bls.gov/cgi-bin/surveymost?ws) for 
the following tables:

     *   Number of work stoppages involving 1,000 workers or more beginning in the period
     *   Number of work stoppages involving 1,000 workers or more in effect in the period
     *   Number of workers involved in work stoppages beginning in the period
     *   Number of workers involved in work stoppages in effect in the period
     *   Days of idleness resulting from work stoppages in effect in the period
     *   Days of idleness resulting from work stoppages in effect in the period, as a percent of estimated 
         working time

       1 Number of workers involved includes only those workers who participated in work
     stoppages that began in the calendar year. Workers are counted more than once if they
     are involved in more than one stoppage during the reference period. Numbers are rounded
     to the nearest thousand. 
       2 Days idle includes all stopages in effect during the reference period. For work
     stoppages that are still ongoing at the end of the calendar year, only those days of
     idleness in the calendar year are counted. 
       3 Agricultural and government employees are included in the calculation of estimated
     working time; private households, forestry, and fishery employees are excluded. 
       4 Less than .005.
