The textile factories of early America weren’t exactly packed with desirable jobs, and became notorious for child labor. One of the most prominent examples: doffers, who were tasked with changing out bobbins full of spun fabric as quickly as possible.
The position often went to boys because they were nimble enough to climb up onto the machines and accepted the low wages, often just a few dimes a day. Similarly, girls were often employed as spinners who watched spinning bobbins for broken threads. Child labor laws ended these practices in the 20th century, and machines took over shortly after.
