Which of the following best describes an employee's commitment to the business?

The best choice for describing an employee's commitment to the business is integration in the business operations. This term reflects how well an employee is woven into the day-to-day functioning and culture of an organization. When an employee is integrated into business operations, it usually indicates that they feel a sense of belonging, are engaged with their work, and are committed to the success of the organization. This can manifest through collaboration with colleagues, participation in team projects, and alignment with the company's goals.

Other options like profit-distribution rights, high variability in tasks, and independent work arrangements do not directly relate to an employee's commitment to the organization. Profit-distribution rights pertain more to ownership and profit-sharing within a company rather than an individual's commitment. High variability in tasks may suggest a dynamic work environment but could also lead to disengagement if an employee does not feel connected. Independent work arrangements can indicate flexibility but may sometimes lead to isolation from the team, potentially weakening an employee's commitment to the organization's collective goals. Thus, integration in the business operations stands out as the most effective descriptor of an employee's commitment.
