                                   MAJOR WORK STOPPAGES IN 2010

     In 2010, there were 11 major strikes and lockouts involving 1,000 or more workers and lasting
at least one shift, the second lowest annual total since the major work stoppages series began in
1947, the U.S. Bureau of Labor Statistics reported today.  The series low for major work stoppages
beginning in a calendar year was 5 in 2009.  The 11 major work stoppages in 2010 idled 45,000
workers for 302,000 lost workdays, a large increase compared to 2009 record lows, with 5 stoppages
idling 13,000 workers for 124,000 lost workdays.

     Average annual major work stoppages have continued to decline by decade.  From 2001-2010,
there were approximately 17 major work stoppages on average per year, compared with 34 per year
from 1991-2000, 69 from 1981-1990, and 269 from 1971-1980.  (See chart 1.)  Total days idle from
major work stoppages from 2001-2010 have also declined over 90 percent from 1971-1980.  (See
chart 2.)

     The longest work stoppage beginning in 2010 was between Temple University Hospital and the
Pennsylvania Association of Staff Nurses & Allied Professionals, lasting 21 workdays with 1,500
workers accounting for 31,500 lost workdays.  The largest work stoppage in 2010 in terms of number
of workers and total workdays idle was the Chicago area construction strike between the Mid-America
Regional Bargaining Association and the Laborers International Union of North America District
Council of Chicago, International Union of Operating Engineers, and Chicago Regional Council of
Carpenters, with 15,000 workers accounting for 180,000 lost workdays.  (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 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.
