The document summarizes the context surrounding Billy Elliot, including:
1) By the 1980s, demand for coal had dropped significantly in the UK due to availability of cheaper oil and gas, requiring closure of unprofitable coal mines and restructuring of the industry. This threatened miners' jobs and local communities.
2) Trade unions organized workers to negotiate wages and conditions, using tactics like strikes and picket lines. However, Thatcher's government prepared for potential strikes by stockpiling coal.
3) Billy's father and brother work in the struggling mining community of Durham. The film explores definitions of masculinity in this setting and how characters conform or challenge the stereotypes.
