Tunde Adeyemi manages a team of 12 software engineers at SystemSpecs Limited in Lagos. He believes his engineers are inherently self-motivated, creative, and capable of self-direction when committed to organisational objectives. He therefore adopts a participative management style. Tunde's assumptions about his employees are consistent with which management theory?

McGregor's Theory Y assumes that employees are inherently motivated, enjoy work, seek responsibility, exercise self-direction, and are capable of creativity when committed to organisational goals. This contrasts with Theory X, which assumes employees are lazy, dislike work, and must be coerced. Theory Z (Ouchi) focuses on long-term employment and collective decision-making, while Taylor's Scientific Management emphasises time-and-motion studies and financial incentives.
