Bachelor Thesis from the year 2006 in the subject Psychology - Work, Business, Organisation, grade: B+, Cardiff University, language: English, abstract: Introduction We always do what we MOST WANT to do, whether or not we like what we are doing at each instant of our lives. Wanting and liking many times are not the same thing. Many people have done what they say they didnt want to do at a particular moment. And that may be true until one looks deeper into the motivation behind the doing. What they are really saying is the price they will have to pay or the consequences they will have to endure, for not doing that something may be too high or onerous for them not to do it. Such as going to work. Many people say they dont want to go to work and yet they do. Which means they dont want to risk losing their jobs and the negative hurting emotions associated with not having a job. It has been estimated about 90% to 95% of all people work at jobs which are unfulfilling and which they dislike and would leave in a minute if they only knew what they really wanted to do. Sidney Madwed (http://www.quotationspage.com/search.php3?homesearch=motivation accessed on 15.02.2006) The quotation defines that nowadays motivation should be an indispensable part of every company. It is a complex and difficult topic and therefore management also has to take historical theories into account. Furthermore, it has to be figured out what employees designate as attractive for defining an effective motivation programme within the organisation. This dissertation will critically evaluate what motivation is and illustrate the different kinds of motivation theories of Abraham Maslow, Frederick Herzberg and Clayton P. Alderfer by explaining the key concepts for managing and motivating people. Due to the fact that motivation, especially employee motivation, is such a broad topic the dissertation will put a specific focus on the similarities and differences between the classical motivation theories.
