Where does this data come from?
This data comes from the Bureau of Labor Statistics work stoppage database. The agency notes that the data is “gathered from public news sources, such as newspapers and the Internet.” The data does not distinguish between strikes, which are usually initiated by workers, and lock-outs, which are typically initiated by management.
