n. (alternative form of big labor English)
Wikipedia
Big labor or big labour is a pejorative term for large, organized labour unions, particularly in the United States. Union supporters typically avoid using the term, preferring instead "organized labour". Related terms include big oil, big tobacco, and big government.
The term "big labour" in the US is applied particularly to the American Federation of Labor and Congress of Industrial Organizations and its constituent unions; smaller, independent unions are less likely to be categorized by their opponents and critics as being representative of "big labour", but they are far from immune. The term " neo-corporatism" has been used to describe three-way bargaining between government, labour unions and big business.
