                                        MAJOR WORK STOPPAGES IN 2012


In 2012, 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 beginning 
in 2012 equaled the total from 2011. Major work stoppages beginning in 2012 idled 148,000 workers, 
higher than 2011 with 113,000 idled workers. In 2012, there were 1.13 million days idle from major 
work stoppages in effect, also higher than 2011 with 1.02 million days idle. (See charts 1 and 2, and 
table 1.) Over 40 percent (8 of 19) of major work stoppages beginning in 2012 occurred in November 
and December. (See table 2.)

The largest work stoppage beginning in 2012 in terms of number of workers and total days idle was 
between the Chicago Public Schools and the Chicago Teachers Union, with 26,500 workers accounting 
for 185,500 days idle. The longest work stoppage beginning in 2012 was between Lockheed Martin 
Corporation and the International Association of Machinists, Local 776, with 3,600 workers 
accounting for 172,800 days idle. (See table 2.) The Lockheed Martin Corporation work stoppage 
lasted 48 workdays. 

The major work stoppage between the American Crystal Sugar Company and the Bakery, Confectionary, 
Tobacco Workers and Grain Millers, Sugar Council resulted in a total of 308,100 days 
idle in 2012, and nearly 445,000 cumulative days idle since beginning on August 1, 2011. The number 
of workers involved in the work stoppage fell below 1,000 workers in December 2012 and will no 
longer be counted in major work stoppage estimates.  



                                        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 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 lost workdays 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.
