Effective quality service hinges on managing employee behavior. This study examinedthe influence of emotional labor on employee quality service delivery among tertiary healthcareproviders in Sub-Saharan Africa, specifically Bayelsa State, Nigeria. Adopting a positivistphilosophical paradigm and a cross-sectional survey design, the study sampled 319 senior cadreemployees using Taro Yamene's formula and stratified sampling technique. Data were collectedthrough self-administered questionnaires, with 291 usable for analysis. The Spearman RankedOrder Correlation Coefficient statistical tool was employed. Findings revealed that emotionaldissonance led to emotional exhaustion, burnout, depression, and job dissatisfaction. Conversely,emotional frequency fostered service confidence, enabling service personnel to better understandpatients' true medical situations. The paper concluded that emotional labor, in the form of bothemotional frequency and dissonance, enhances service personnel's work performance. The timespent with patients creates an atmosphere of trust, likeness, and respect between personnel andtheir patients. Tertiary healthcare facilities are urged to consistently monitor service personnelbehavior to identify those who may be psychologically derailed by strenuous working conditions.Such monitoring can help these facilities better address the demanding nature of healthcare jobsand improve the quality of service offered to patients, ultimately reducing medical tourism.
