Answer:
An independent Contractor
Explanation:
Some times a firm will opt to complete a work using workers that do not work for them. An independent contractor is a person who legally works with people without having to adhere to all the norms and rules of the firm. An independent contractor works on his own with no organizational attachment.
For example, Google has a large number of employees, and they contract a project to Mr. Smith, who is a non-google Employee that works for himself. Mr. Smith is an Independent Contractor.
Therefore the person is an independent contractor.
