Abstract:

Because I am working at this job through a contract, rather than as a regular employee, there are some situations unique to my position. In the technical writing industry, many writers work on a contract basis through an agency. This type of employment is called contracting, although you may also hear it called consulting. I prefer the term contracting because I associate consultants with people whose job is to advise a company on one issue or another. That may or may not describe a particular technical writing assignment.
