Preschool teachers’ emotional labor influences their Psychological capitalPsychological capital is the positive energy in a preschool teacher’s personal traits. Kahn (1990) believed that job involvement is mainly influenced by psychological conditions such as psychological meaningfulness, safety, and availability. Psychological meaningfulness is the value gained from a work goal or purpose and is judged in relation to a person's ideals or standards. Psychological safety is the experience of being able to act in a manner that is natural to that person and being able to use and employ all skills and knowledge in a role without fear of being ridiculed or of experiencing negative consequences. Psychological availability is the capability to engage as a result of having cognitive, emotional and physical resources. Previous studies on psychological labor have emphasized that its individual elements can facilitate an employee's job satisfaction, organizational commitment, sales performance, leadership effectiveness, and work effectiveness whilst reducing personal work pressure and demission rates and increasing organizational drive, transformation, and productivity (Avey, Patera & West, 2006; Peterson, Luthans, Avolio, Walumbwa, Zhang, 2011).
