Read this excerpt from a passage.
Mechanization took another leap during the 1930s, when machines were introduced into many workplaces in order to increase productivity. Instead of hiring workers to perform tasks on an assembly line, factory owners used automated machines that could do the work of several people. Then, in 1954, George Devol created the Unimate, a robotic arm. The Unimate began working on the assembly line at General Motors in 1961, taking on unpleasant, dangerous, and repetitive tasks. This robotic worker had many advantages over human workers. The Unimate did not require a salary, followed company rules, and never called in sick (although it did require the occasional repair). In addition, the Unimate could work twenty-four hours a day, seven days a week. Manufacturers that used the Unimate and other industrial robots saw a marked increase in productivity and a decrease in labor costs. With the rise of industrial robots, many unskilled laborers lost their jobs. A single robotic "arm" or "hand" could do the work of several humans. Robots could work faster and more accurately. They did not get tired or lose concentration.
What was an effect of mechanization being used in the workplace?
Companies that used mechanized robots saw a decrease in productivity and increase in costs.
The Unimate worked 27/7 without downtime or need of repair.
Manufacturers used industrial robots in place of people, causing many unskilled workers to lose their jobs.
Assembly lines in manufacturing companies became a thing of the past.
