Human capital is a pertinent driver for business success and sustainability. Employee outcomes are positively related to the effective execution of HRM practices. Paying attention to how HR procedures are carried out is crucial for the effectiveness of HRM.  Therefore, a workshop “HR for non-HR" was delivered to facilitate six HR functions practically to non-HR employees.  The evaluation of the workshop's effectiveness is the main aim of this study using the first two levels of the Kirkpatrick model: reaction and learning in a quasi-experimental design. The objectives of this study are to (1) examine whether HRM workshop sessions would improve participants' learning of HRM and its practices using pre- and post-workshop structured tests. (2) evaluate participants' reactions toward the conducted workshop using a structured survey.  (3) collect in-person feedback from the participants. The results indicated a significant change in the learning level of the overall HRM and all six HR practices except the performance management system and positive reactions of the participants toward the workshop. The correlation analysis emphasized the importance of the training content and the training planning and administration. Most of the participants agreed on the outstanding performance of the facilitators despite being students. Studying the effectiveness of such a workshop on a large scale of participants is highly recommended for future studies.
