Step-by-step explanation:
In the era of industrialization, there were significant issues with working conditions. Workers had to toil for long hours in dangerous and often unsafe environments. They were subjected to low wages, lack of job security, and limited control over their working conditions. The extreme poverty of many workers made it difficult to consider them truly free, despite not being bought or sold by their employers. Workers' rights, wage protection, and safe work environments became important concerns during this time.
