Labor law is the body of law which address the legal relationship between trade unions, employees, and employers -- including collective bargaining, union organization activities, and the negotiation of strikes and lockouts. Labor law arose due to the demands for workers for better conditions, the right to organize, and the simultaneous demands of employers to keep labor costs low. Labor law attorneys may represent their clients in matters before the National Labor Relations Board (NLRB), which hears disputes between employers and unionized employees.
Charleroi is a borough in Washington County, Pennsylvania, along the Monongahela River, 25 miles south of Pittsburgh. Charleroi was settled in 1890 and incorporated in 1891. The population in 1900 stood at 5,930; in 1910, 9,615; in 1920, 11,516, and in 1940, 10,784. The population was 4,871 at the 2000 census. There has been a large-scale cessation of industrial activities in the region. The decrease in the population is associated with the decline of the steel-making industry in the "Mon Valley" which extends from Charleroi to the mouth of the Monongahela at Pittsburgh.
