Orientation: Reward has links to employee attraction and retention and as such has a role to play in managing talent. However, despite a range of research, there is still lack of clarity on employee preferences relating to reward.Research purpose: The purpose of the research was to recommend and appraise a theoretical model of the relationship between occupational culture dimensions and reward preferences of specific occupational groups in the South African context.Motivation for the study: The motivation for this study was to address the gap that exists with reward preferences and occupational culture with a view to identifying and gaining insight into individual preferences.Research design, approach and method: A structural equation modelling approach was adopted in exploring the proposed relationships. A South African Information, Communication, and Technology (ICT) organisation served as the population, and a web-based survey assisted in gathering study data (n = 1362).Main findings: The findings provided support for the relationship between occupational culture dimensions and certain reward preferences. In particular, statistically significant results were obtained with the inclusion of the Environment, Team, and Time occupational culture dimensions as independent variables.Practical implications and value-add: The study provides workable input to organisations and reward professionals in the design of their reward strategies and programmes.Keywords: compensation; employee preferences; occupational culture; remuneration; reward preferences

Abstract At present, the lack of UAV regulations and standards precludes UAVs from being certified to operate commercially in un-segregated civilian airspace. Because of strategic, economical and security requirements, it is necessary to devise a method to operate UAVs in South African airspace within existing regulatory arrangements. This paper suggests specific UAV missions, viz; maritime patrol/boarder control, search and rescue, and cargo transport, together with design considerations and possible concepts of UAV; operations, maintenance and training, that will enable UAVs to satisfy the immediate South African strategic requirements whilst further UAV standards and regulations are being developed.

Modelling Approach

By putting in place a performance appraisal scheme, employees who improve their work efficiency can then be rewarded, whereas corrective action can be taken against those who don’t. The aim of this paper is to develop a technique that helps to measure the subjective effect that a given rater’s assessment will have on the performance appraisal of a given employee, assuming that an assessment of one’s work performance will have to be undertaken by a rater and that this rating is essentially a subjective one. In particular, a linear mixed modelling approach will be applied to data that comes from a South African company which has 214 employees and where an annual performance evaluation has been run. One of the main conclusions that will be drawn from this study, is that there is a very significant rater’s effect that needs to be properly accounted for when rewarding employees. Without this adjustment being done, any incentive scheme, whether its motive  is reward based or penalty based, will ultimately fail in its intended purpose of improving employees’  overall performance.
