Answer:
on a contract
Explanation:
An employee can be defined as an individual who is employed by an employer of labor to perform specific tasks, duties or functions in an organization.
Basically, an employee is saddled with the responsibility of providing specific services to the organization or company where he is currently employed while being paid a certain amount of money hourly, daily, weekly, or monthly depending on the contractual agreement between the two parties (employer and employee).
Any employee working for companies on a contract simply means or implies that, he or she work on a project-by-project basis rather than as a full-time employee.
For instance, a freelancer is someone who offers or provides his or her service to other employer of labor (business organization) without entering into a long-term contractual agreement.
