Abstract:

This research aims to evaluate the influence of fixed and variable compensation on autonomous motivation at work. The research mobilizes the self-determination theory. It consists of two separate studies based on two samples of 147 and 137 employees of the same wine cooperative. The aim of the first study is to test a research model that attempts to explain the effects of the fixed compensation level on autonomous motivation and job satisfaction, as well as on a set of related behaviors. The results support the hypothesis that perceived organizational support fully mediates the relationship between fixed compensation and autonomous motivation. This study also supports the hypothesis that autonomous motivation fully mediates the relationship between perceived organizational support and engagement, and that engagement fully mediates the relationship between autonomous motivation and job satisfaction. The aim of the second study is to test a research model that attempts to explain the moderating effects of variable compensation on the relationship between autonomous motivation and performance at work. The moderating effects of individual and collective compensation are studied in a differentiated way. Similarly, task, contextual and adaptive performance is examined in a differentiated way. The results of the study support the hypothesis that autonomous motivation is positively related to, task, contextual and adaptive performance. This study also supports the hypothesis that individual compensation positively moderates the relationship between autonomous motivation and the different facets of performance.
