Work Stoppages

Work Stoppages: 2010-2019

The Work Stoppages Program publishes monthly and annual data on major work stoppages in the United States. Major work stoppages are defined as any stoppage that involves 1,000 or more workers and lasts for at least one full work shift.

Number of work stoppages

The Work Stoppages Program tracks the number of stoppages that occur each month and year using two different metrics. The first metric is a count of the number of work stoppages that began in the given month or year. This tracks how many new stoppages began within the month or year being considered. The other metric used for the number of stoppages is the number in effect. This is a count of any stoppage observed in a particular month or year. Specifically, this includes stoppages that began in a previous month or year and continued into the time period being considered. The following chart displays the total number of work stoppages beginning and in effect each year from 2010–2019.

Ownership breakdown

One of the metrics published by the work stoppages program is a cumulative “days idle” for each work stoppage. This metric represents the number of workers involved in a stoppage multiplied by the number of workdays a stoppage lasted. The result is a total number of workdays that were missed as a result of the work stoppage. In the following chart, the 2010-2019 days idle from work stoppages have been broken down by ownership group to show what percentage of days idle was from stoppages in the private industry, state government, and local government ownership groups.

Industry sector breakdown

The Work Stoppages Program specifies the industry sector for each published work stoppage in the database. In terms of the number of work stoppages that began between 2010-2019, educational services, as well as healthcare and social assistance, saw far more activity than other sectors in this timeframe. Although the healthcare and social assistance sector saw more work stoppages beginning than educational services, educational services included many large stoppages which make it particularly interesting to consider in this timeframe. The chart below shows the number of work stoppages beginning between 2010-2019 broken down by industry group.

From 2000-2009, educational services sector stoppages accounted for 12.4% of all stoppages beginning in the timeframe, compared to the 2010-2019 timeframe where educational services stoppages accounted for 24.7%, almost twice as much. Looking specifically at the two years where educational services work stoppages spiked, 46.7% of all stoppages beginning in those years were in the educational services sector. From 1993-2019, there was an average of 3.4 educational services sector work stoppages that began each year.
