                                      MAJOR WORK STOPPAGES IN 2015


In 2015, there were 12 major work stoppages involving 1,000 or more workers and lasting at least one 
shift, one more than in 2014, the U.S. Bureau of Labor Statistics reported today. Since the series began in 
1947 the lowest annual total was 5 in 2009. (See table 1 and chart 1.)

Major work stoppages beginning in 2015 idled 47,000 workers, higher than the 34,000 workers of 2014. 
In 2015, there were 740,000 days idle from major work stoppages in effect, also higher than 2014 with 
200,000 days idle. In 2015, private industry organizations accounted for over 92 percent of the total days 
idle, consisting of 684,000 days of idleness. In 2015, oil and gas extraction, manufacturing, and 
educational services industries accounted for approximately 89 percent of all days idle for major work 
stoppages in 2015. (See tables 1 and 2 and chart 2.)   


In 2015, the largest major work stoppage in terms of days idle was between Royal Dutch Shell Oil and 
other refineries, and the United Steelworkers Union with up to 6,600 workers at its February 2015 peak. 
This work stoppage accounted for 322,100 total days idle. Other major refineries involved in this work 
stoppage included British Petroleum, Chevron, Exxon Mobil, LyondellBasell, Marathon Oil Corporation, 
Motiva Enterprises, and Tesoro Corporation.

The second largest work stoppage in 2015 in terms of days idle was between Allegheny Technologies 
Incorporated and the United Steelworkers Union, involving 2,200 workers with 206,800 days idle. This 
work stoppage was still ongoing at the end of 2015. (See table 2.)




                                            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 this publication.

Information on work stoppages is obtained from reports from the Federal Mediation and Conciliation 
Service, state labor market information offices, BLS Strike Report 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 
www.bls.gov/wsp.  

Monthly time series data since 1981 have been published (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

Detailed historical major work stoppages data

Detailed data for each major work stoppage since 1993 are available at 
www.bls.gov/wsp/monthly_listing.htm. The major work stoppages historical data file includes the 
organization involved, location, beginning and ending work stoppage dates, the number of workers, and 
total days idle.

       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.
