How did workers' unions turn workers' individual difficulties into social questions?

Correct answer: They gave organized and public form to the demands of many workers

The direct answer is A. A worker may first experience low wages, unsafe conditions or excessive hours as a personal problem. When many workers discover that they face the same problem, a union can collect their complaints, discuss common demands and present them publicly to an employer or government. A union can negotiate, organise a strike and demand rules applying to all workers. In this way, a private difficulty becomes a social question about justice, wages, working time and rights. Option A is correct because it explains organisation and public expression of collective demands. Option B is wrong because isolated complaints do not create strong collective power. Option C is wrong because hiding owners’ profit does not represent workers’ demands or solve their conditions. Option D is wrong because increasing feudal dues is unrelated to industrial workers’ organisation and would worsen burdens. Remember: one worker’s complaint is personal; many workers’ organised demand becomes a labour issue and a political question.
