Consider the following propositions about McGregor's Theory X and Theory Y:
I.   Theory X assumes employees are inherently passive, avoid responsibility, and require close supervision and coercive management to achieve organisational goals.
II.  Theory Y assumes employees can exercise self-direction and self-control, and that the capacity for creativity and problem-solving is widely distributed — not confined to management.
III. McGregor advocated that Theory X assumptions are empirically more accurate for the majority of the modern workforce, making autocratic management styles necessary for most organisations. Which of the above is/are correct?
