Abstract
The “tingi” or retail concept has been a part of the Philippine culture. Filipinos embrace the concept since it allows them to buy conveniently at a lower cost and without the pressure of buying in bulk. In addition, due to the rapid growth rate of Retail Industry in the Philippines, retail companies are aggressively expanding its market security by putting up more stores. Given this aggressive expansion, manpower working in convenience stores will also increases and which may result to increase number of employees experiencing muscle fatigue. This study aims to determine the associated possible factors affecting the severity of muscle fatigue experienced by convenience store employees. A survey questionnaire was distributed to one hundred thirty seven (137) respondents. Twelve (12) factors were considered and analyzed using ordinal logistic regression. Results showed that six (6) factors namely, age, length of stay, working hours, type of work (selling area and security) and customer count were significantly contributors to the occurrence and severity of muscle fatigue.
