Organisations are constantly trying to change and develop themselves so that they are better equipped to face challenges that exist within the greater macro environment. These changes affect all facets of the organisation and often have a life altering impact on the employees involved. One such impact that this fluctuating corporate environment has had on employees is that they are required to develop themselves to safeguard against unexpected changes that may jeopardise their job security. Employees are constantly trying to improve themselves and their marketability so that they may progress in their careers. The major shift from previous decades is that employees are currently more committed to their careers than to their organisation (Cavanaugh & Noe, 1999). Moving up the organisational hierarchy is one way to achieve career development (Garavan, Collahan, 1996) and may be regarded as reward for the self-development that one has worked so hard for. If employees do not see an opportunity to further themselves and their careers, a possible response would be to leave the organisation and look for other avenues to achieve this development. The present study aimed to explore this by determining how a personality construct effects ones perceptions of intraorganisational mobility and the reactions that these perceptions generate. A large South African banking institution was used to sample employees for the study and being a service firm, all indications are that it is an extremely underresearched organisational form (Malos, Campion, 2000). The key strategic focus of the group is said to include among others, to focus on customer service, to improve transparency and to meet transformation goals in line with the financial sector charter. This is in response to numerous restructuring and change efforts that have taken place within the last two years. The organisation serves as an illustration of corporate life within South Africa. The company is continually trying to change and develop to meet the challenges of the greater macro environment. In doing so, the employees are required to respond proactively to the changes that take place and develop themselves accordingly. In light of this, the organisation provided a useful backdrop from which to analyse the relationship between locus of control, perceptions of intra-organisational mobility, satisfaction with promotion opportunities and future career planning.
