When someone avoids or neglects their duties or responsibilities, they can be referred to as shirkers. However, there are several other synonyms that can be used to describe someone who shirks, including procrastinators, slouches, loafers, idlers, dodgers, shunners, and evaders. Procrastinators delay tasks, while slouchers and loafers lack motivation. Idlers are lazy individuals who don't like to work, while dodgers and shunners are people who try to avoid tasks. Evaders are those who run away or hide from their duties. While each word has its own subtle connotations, they all share the common meaning of not fulfilling responsibilities.
