Freelancers are self-employed individuals who are not contractually bound to one specific employer. Freelancers can work in virtually any sector, though most work in marketing and communications, creative arts, and information technology. Essentially, a freelance job is one where a person works for themselves, rather than for a company. While freelancers do take on contract work for companies and organizations, they are ultimately self-employed.
Freelancers are responsible for all sorts of things that traditional employees are not, such as setting their work hours, keeping track of time spent on different projects, billing clients, and paying their own employment and business taxes. Freelancers are not considered “employees” by the companies they work for, but rather “contractors.”
