In the mining company case study, the volume of mining was increasing and the workload of laboratory and sample house employees was also increasing. It is important to investigate the physical workload after production increasing. The purpose of this study is to analyze and evaluate the physical workload for laboratory and sample house (LSH) departments. Full-Time Equivalent (FTE) is used to determine the level of the physical workload. The job description and the competences of employees will be used to understand, calculate, and evenly distribute the physical workload. Furthermore, data is collected through several methods such as discussions, interviews, questionnaires, and observation. The result of the study can provide the best strategy for reducing the unbalance of the physical workload at LSH and this study can be used to determine the cost and impact of recruiting employees based on an analysis of workforce planning as well as for workers, workers can avoid mistakes and can work safely.
