People who worked in factories in the late 1800s usually faced unsafe conditions. short hours. complex tasks. difficult training.

Unsafe conditions

Explanation:

Working conditions at that time were very poor, there was no rational delimitation of work hours, with workloads reaching up to 16 hours a day, there were not enough labor rights and minimum guarantees of working conditions,  there were numerous accidents due to the lack of safety in the work environment and there was much exploitation even of child labor.

On account of this, the proletariat organized itself politically in search of the creation of its rights, as well as the respect for its dignity, a fairer division of the fruits of labor and the guarantee of security at work, a fact that promoted socialism in Europe in the century XIX, initiating an ideological dispute that defined Europe and, consequently, all western world, being relevant until the present day.

- "the civil rights movements"

- "following the american civil war and abolition of slavery, the united states entered a period known as reconstruction, during which black americans continued to suffer from disenfranchisement, racial segregation, and economic oppression. beginning in the early 1950's, black americans launched a series of major campaigns of civil resistance, emphasizing the need for nonviolent protests and civil disobedience."

"such as the montgomery bus boycott of 1955-56, a campaign launched by rosa parks against the policy of racial segregation of the public transit system in alabama. “sit-ins” became popular across the american south, particularly in greensboro, north carolina, increase national sentiment."

- "the counterculture movement"

- "counterculture began to develop in the united states following the rise of conformity in american culture during the 1950s. by 1963, youth, particularly those of the white middle class, began rejecting the cultural standards and normality of their parents, opting for progressive attitudes instead. the movement gained momentum as the civil rights movement became increasingly successful and as the u.s. military intervention of vietnam began to take a negative turn."

"hippie counterculture moved further into popular culture following the summer of love in 1967 when thousands of people came together in the haight-ashbury neighborhood of san francisco. along with greenwich village in new york city, haight-ashbury became a hub for the counterculture movement."
