Especially now-a-days, the issue of career development is a basic concern for the most, if not all, employees, who are trying to develop through their work, in order to reach a higher level of employment and economic power. However, this development isn't an easy process, especially for new employees in the labor market. A new and highly efficient solution is an advisory process, widely known as mentoring. In mentoring, each employee develops a counseling relationship with a mentor, who usually has more experience than the employee and therefore undertakes to guide him in his professional career. This paper investigates career development issues through mentoring in the case of non-dependent work relation for the company LR Health & Beauty Systems. The purpose of this research is to explore whether mentoring contributes to employee's career development who are working on the network company LR Health & Beauty Systems. The research part of this study is based on a questionnaire, which was distributed to company's employees and is related to mentoring issues.
