I may be rude or mean at times but i've never been that low to tell someone to kill themselves.

The three main organizational levels are: strategic, managerial and operational.

Explanation:

At the strategic level, upper management is in charge of developing the overall strategy of the organization and setting the goals and objectives. Managers must apply sophisticated analysis techniques to monitor the strategic performance of the organization.

At the managerial level, middle management must evaluate how the company is operating in order to identify and adapt changes. Managers must analyze large amounts of information to ensure that the short and medium range plans and budgets are being followed, as well as the organization's policies, procedures and business objectives.  

At the operational level, lower management is in charge of controlling, developing and maintaining the organization's core activities which are the ones that really make the whole organization function. Many times, managers must make quick decisions to correct any deviation from the normal structured activities. Most of the decisions made are usually repetitive and structured also.
