Bad psychological working environment means high costs for the employees envolved, the workplace, the public sector and for the Danish society in general. The psycological working environment is important for the performance of public workplaces and has to be prioritized for both financial and social reasons. Moreover, managers can make a difference by using their skills and personal competences.
However, the public organizations’ initiatives towards improving psychological working environment are seldom evaluated. Furthermore existing research often have an individual orientation at the expense of an organization approach. Return On Investment (ROI) is a relative new and mathematical method to evaluate the efficiency of an investment or to compare the efficiency of a number of different investments. ROI measures the amount of return relative to the investments cost while symbolic and other strategic effects are not taken into account. Moreover, ROI is developed in the private sector and does not include the characteristics of public organizations. This paper presents first draft of a model to evaluate the effects of initiatives towards the psychological working environment in public organizations. Evidence from the literature and data from Danish municipalities are used to create pro and cons argument towards the evaluation model. Finally the paper will reflect on the possibilities of using traditional effect evaluation models to evaluate the effects of initiatives towards the psychological working environment.
