The COVID-19 pandemic has had a significant impact on the nutrition, health, and work-life balance of employees, particularly teachers who have switched to blended work setup. This led the researcher to come up with a study about the dietary diversity of Public and Private High School Teachers in Batangas City in a blended work environment during the pandemic with an aim of describing the sociodemographic characteristics, determining the dietary diversity scores and nutritional status of the teachers, and relating these variables to one another. Through a descriptive-survey design and convenience sampling, the researcher gathered 60 Public and Private High School Teachers. Overall, the study found that most of the teachers (56.67%) have medium dietary diversity and a majority also has a normal nutritional status (83.33%). Further, on the average, the teachers spent 3 to 5 days working from school. Results also show that there is a significant relationship (p=0.029) between the average monthly income of the teachers and their dietary diversity scores. However, the dietary diversity scores of the teachers do not have a significant relationship with their nutritional status (p=0.905). From the results of the study, the researcher suggests that there be a promotion of nutritional wellness programs and improvement in food environments for both home and workplace setup to maintain and improve the nutrition of the teachers.
