Works councillors are elected representatives of employees in German companies. It is their job to protect and bargain the interests of the employees with the company. We investigated the impact of 558 works councillors' individual political skill on their career success, where career ascendancy is based on success in upward elections and not on appointments by supervisors. The participants were from core German industries mostly working in large companies. We found that the stronger works councillors' political skill the more successful they were in their career still after controlling for sex, age, and union membership. Implications and limitations of the study and consequences for future research are discussed. (Contains 2 tables.)
