In this theory, management assumes employees are inherently lazy and will avoid work if they can and that they inherently dislike work. As a result of this, management believes that workers need to be closely supervised and comprehensive systems of controls developed. A hierarchical structure is needed with narrow span of control at each and every level. According to this theory, employees will show little ambition without an enticing incentive program and will avoid responsibility whenever they can. According to Michael J. Papa, if the organizational goals are to be met, Theory X managers rely heavily on threat and coercion to gain their employees' compliance. Beliefs of this theory lead to mistrust, highly restrictive supervision, and a punitive atmosphere. The Theory X manager tends to believe that everything must end in blaming someone. He or she thinks all prospective employees are only out for themselves. Usually these managers feel the sole purpose of the employee's interest in the job is money. They will blame the person first in most situations, without questioning whether it may be the system, policy, or lack of training that deserves the blame. A Theory X manager believes that his or her employees do not really want to work, that they would rather avoid responsibility and that it is the manager's job to structure the work and energize the employee. One major flaw of this management style is it is much more likely to cause diseconomies of scale in large picture.
