About 1 in 4 worked part time in 2014. Some writers keep regular office hours, either to stay in contact with sources and editors or to set up a writing routine, but many writers set their own hours. Freelance writers are paid per assignment; therefore, they work any number of hours necessary to meet a deadline. As a result, writers must be willing to work evenings and weekends to produce something that is acceptable to an editor or client. Although many freelance writers enjoy running their own business and working flexible hours, most routinely face the pressures of juggling multiple projects or continually looking for new work.
