Who is defined as the individual hired to perform work and bound by the manner in which it is executed?

The individual hired to perform work and bound by the manner in which it is executed is known as an employee. Employees typically enter into a contractual relationship with an employer, wherein they agree to fulfill certain tasks and responsibilities as designated by that employer. This relationship often emphasizes the employer's right to dictate how and when the work is done, which is a defining characteristic of employment. In such arrangements, the employee may have specific duties, but the employer generally has control over the processes and methods used to accomplish those tasks.

In contrast, an employer is the entity or individual that hires and supervises employees, while the terms endorser and endorsee relate to different contexts, specifically in agreements involving endorsements or sponsorships, where one party promotes or supports the work of another. These distinctions clarify why the term "employee" is the appropriate answer in this scenario.
