*Limitations and Strengths*

There were some flaws in how the study was conducted that need to be pointed out. It is important to consider the limitations of our study including the sample size and specific geographic location. Further research with a larger sample size and diverse location is needed to further understand the effectiveness of RTW programs for disabled workers during the COVID-19 pandemic. The data collection was conducted using a purposive sample, which refers to situations during the pandemic that allowed researchers to approach the subjects through indirect encounters or online, which profoundly affected the willingness of participants to continue with the study, resulting in possible biases. There are, nevertheless, certain advantages to consider. We demonstrated the importance of contextual factors in implementing RTW, especially when examining the program's outcomes in measuring the functional ability and quality of life of workers with disabilities. This was carried out by using various data from very different social and cultural backgrounds and a wide variety of social assistance background frameworks.
