1.1       Background of the Study

Leadership is an important area in management that occupies of central position in our everyday life.  It involves the still of leading and dealing with people.  One thing among human group is that there is always a leader otherwise the group cannot live to achieve its purpose.

The success in leading a group is contingent upon both leaders ability to held power effectively and the existence of an opportunistic situation.  The problems which result within organizational members disagree on both the nature of the goals of which people aspire, and the art of leadership.  Leadership according to Olusoji (2012) refers to behaviour undertaken within the context of an organization that influence the ways in which other organizational members behave.  It could be observed that leadership and management envisages deeply into what the organization can achieve if the quality of recognition is accorded to them.  Leadership has been propounded to include the source of influence that are built into position in an organizational hierarchy.  These include organizational sanctioned rewards and punishment authority and also export power.  It could be seen however that subordinates within the organization, though not all seen to enjoy the influence that exist all over the above organizational hierarchy provided by them in the organization.

Leadership is very essential in organization because achievements and results occur vis-à-vis the tracts being projected by leader.  Leadership includes the ultimate source of power but has the positive ability in persuading other individual and to be innovative in decision making.  Problems are sound to occur within every noted organization.  Decision making is found to generate conflicts in whatever they are doing to achieve organizational goal.  In the light, the notions of leadership act are these which help a given organization in meeting those stated objectives (Barelas, 2010).

Dennis (2008) opines that in the society today, not only the presence of reward (positive and negative) or the incentive appraisal could induce productivity but the feeling of belongingness.  Further expressions like, is it my father’s work?  “They can dismiss me, I don’t care”, “why should I kill myself for them”?  There are some of the uncountable expressions often used by Nigeria workers to show that attitude to work.  Whenever any of these expression are heard, one will readily know that something is wrong somewhere in the entire system, so meaningful economics development, growth and self reliance would not be obtained where unsuitable leadership style is in place, therefore, how far an organization succeeds in achieving its goals depends to a large extent on how the management and workers relationship are handled in the organization, and this effect workers psychological expectation.

In the light of the foregoing, this study aim is to look at the leadership style, the organization should adopt to attain better performance.  The research will also try to examine the philosophy of leadership and its functional relationship with employees performance in an organization.  Therefore, to discover more means of finding a lasting solution to the numerous problems facing leadership styles on employees performance.  The increasing force of competition have awakened the minds of organizational management to develop and acquire new technique and mechanism to increase the level of organizational efficiency and effectiveness.  This task requires resources of the organization involved in production namely – money, material and labour which need to be confirmed appropriately for effective performance.

1.10    Historical Background of 7UP Bottling Company

The Seven-Up bottling company Plc is one of the largest independent manufacturer and distributor of the well-known and widely consumed brands of soft drinks in Nigeria. Our brands are Pepsi, 7UP, Mirinda, Teem and Mountain Dew, which we produce and market in all our present 9 manufacturing plants. We also market our products through our over 200 distribution centres that we also call depots spread over the nooks and crane of Nigeria. Our workforce is currently in the neighbourhood of 3500 employees.

A Lebanese Mohammed El-khalil who came to Nigeria for the very first time in 1926 founded the company. Mohammed is the father of the company’s current chairman Faysal El-Khalil. The company metamorphosed from a very successful transport business [El-Khalil Transport] in a bid to diversify the then largest transport company in the entire West of Africa. On October 1st 1960, the exact day our great country Nigeria won her independents, Nigerians also experienced the birth of a soft drink giant as the first bottle of 7Up rolled out from our factory located in Ijora. Since then, our company continued to grow in the leap and the bound. In the late 80s, we established two more plants in Ibadan and Ikeja. In the early 1990s when Pepsi International took over 7Up international, we again got great opportunities to introduce the Pepsi brand to the Nigeria people. As at today, the company has its Headquarters in Beirut and operational base in three African countries; Nigeria, Tanzania and Ghana.
