  Workplace learning is used to train employees systematically, e.g., via
e-learning or in 1:1 training. However, this is often deemed ineffective and
costly. Whereas pure e-learning lacks the possibility of conversational
exercise and personal contact, 1:1 training with human instructors involves a
high level of personnel and organizational costs. Hence, pedagogical
conversational agents (PCAs), based on generative AI, seem to compensate for
the disadvantages of both forms. Following Action Design Research, this paper
describes an organizational communication training with a Generative PCA
(GenPCA). The evaluation shows promising results: the agent was perceived
positively among employees and contributed to an improvement in self-determined
learning. However, the integration of such agent comes not without limitations.
We conclude with suggestions concerning the didactical methods, which are
supported by a GenPCA, and possible improvements of such an agent for workplace
learning.
