Training is an essential element to consider when boosting line managers skills. However, some abilities demanded by line managers, such as evaluating the performance of their employees, may not be given through training. Thus, it is unreasonable to require such skill if line managers are not be trained to accomplish it precisely. Hence, this study primarily aims to determine whether line managers are being trained to appraise the performance of employees in Ireland and Brazil. It was utilised a quantitative cross-sectional design and an appropriate sampling to collect information from line managers working in Ireland and Brazil. An online questionnaire was applied for the procedure of data collection. The gathered data was examined through a descriptive method, which was demonstrated by frequencies and percentages via tables and charts. A total number of 103 line managers, 45 working in Ireland and 58 in Brazil cooperated in this study. This study demonstrated that most of the line managers respondents, both working in Ireland and Brazil, had not received training to appraise the performance of their employees. Nevertheless, there is a piece of evidence by some that they were trained in this matter. The analyses also showed that LMs working in Brazil responded that lack of feedback culture is the most challenging element when dealing with evaluations of their employees’ performance. By contrast, in Ireland, most respondents reported lack of HR skills as well as lack of time.
