The goal of this article is to raise interest to the problem of identifying the reasons for unwillingness to work in project-type organizations. The article addresses the following issues: whether there are employees in projects, program and portfolio who do not want to work in such type of the organizations initially (before being involved in the project), or perhaps unwillingness to participate/work in some projects has appeared during execution of some project processes. Reasons, or the vital necessity due to which such kind of category of personnel is in the temporary project organization are considered, for example: availability, or lack of project management standards, financial needs, there is no other work for this period, etc. Also, in this article we make an attempt to determine what is the percentage of employees in projects who has the necessity to work in projects for any reasons; does this part of employees negatively impact the success of projects and, as a consequence, on the programs and portfolios. So, the main focus of this work is directed to those category of employees who do not want to participate in project sphere and the impact of the personnel group on processes, elements and results of any project.
