The study's principal purpose was to discover the mediating effect of technological developments on the relationship between work-life balance and hotel front-line employee engagement in the hospitality industry. Using the statistical tools mean, Pearson r and regression, an adaptive questionnaire measured the level of technological innovations, work-life balance, and employee engagement of hotel front-liners. A quantitative method was employed to select 274 employees through simple random sampling of various hotel employees in the Davao Region. Furthermore, technological innovation is significantly related to and positively affects employee engagement, implying that as technological innovation rises, so does employee engagement. Still, it found a negative correlation, implying that increased work-life balance leads to decreased employee engagement. Lastly, the Sobel test yielded a zvalue of -.583 with a p-value of 0.01, significant at 0.05 level. The original direct impact of work-life balance on employee engagement improved upon the addition of technological innovations
