This study aims to examine religious discrimination against Muslim workers. There are three objectives in this study, namely to identify the level of discrimination against Islam, to identify differences in the level of discrimination against Islam between the sexes, and to identify differences in the level of discrimination against Islam between employers of different religions. Purposive sampling and snowball sampling methods were used to select a sample consisting of Muslim workers working as salesmen. A total of 132 questionnaires were analyzed from four different shopping complexes in Johor Bahru, Johor. The results of the study found that the level of religious discrimination is at a low level. In addition, researchers also found that male workers were more likely to experience religious discrimination than female workers. In terms of the religion of employers, non-Muslim employers are more likely to discriminate against religion than Muslim employers. In conclusion, in the context of this study, religious discrimination against Muslim workers is at a low level.
