Answer:
Theory Y
Step-by-step explanation:
Theory X and Theory Y were developped in the late 1950's, by Douglas Mc'Gregor a mangement theorist and professor.
Theory X says that employees need close supervision and a system of external rewards and penalties, since they're not (or little) commited to their work and tend to avoid reposibility. The application of this theory tends to be beneficial for employees involved in a sigle-focused and repetetive task (like in an assambly line type-of-job).
Theory Y holds quite the opposite. It's based upon the assumption that employees are internally motivated and are committed to work by themselves, therefore, they don't need direct supervision. This theory works better for workplaces where creativity is key for goal-completion, (like for a content creator or a web site designer).
