It would be difficult to state which 'posts' come under what. Normally, the job profile is the consideration for Junior/Senior Management. The profile with the least amount of decision-making would be a Junior Management Position. Executives/Assistant Managers are normally in this category. The profile with a moderate level of decision-making would be a Middle Management Position. Managers/Senior Managers are normally in this category. The profile with a high level of strategic decision-making would be a Senior Management Position. General Managers/VP/CEO fall under this category. But still, to define, the job profile is the most important factor.
