Supermarkets are one of the important places in the commercial area because people can find their necessities and luxuries here. Thus, there are a lot of people who tend to go to this place. Due to the pandemic era, people can easily spread the virus if social distancing is not maintained. There is a possibility that the virus can easily spread in supermarkets especially in paying on counters and waiting in counter lanes. Some of the supermarkets are not maintaining social distancing protocols based on the result of this study. The researchers also observe that some of the devices used in the supermarket counter are not appropriate in the body dimensions of the cashiers. With the help of the Ovako Working Posture Analysis System and Rapid Entire Body Assessment, the researchers determine the working postures of the cashier. The findings of this study show that the current check-out counter design is not applicable in new normal and can also produce musculoskeletal disorders to the cashiers. Considering the findings of the research, social distancing should maintain, and the proper ergonomic dimension of the check-out counter is needed. To attain this, the researchers develop a new design of the check-out counter.
