Answer:
Independent contractors.
Step-by-step explanation:
An independent contractor is a person that provides goods or services under a contract with a company. Contractors do not work on a regular basis but as required by the employer. Contractors are subject to the law of agency and are regarded as agents representing the interests of the company.
There is uncertainty associated with persons that are independent contractors as they do not have a binding relationship with the employer. They can easily be disengaged.
