Based on the Conservation of Resources Theory, this research aims to examine the relationship between seasonal employee leadership (SEL) and turnover intention (TI). The data was obtained by administering a survey to 450 seasonal employees working in 15 five‐star hotels in Antalya. The findings revealed that SEL reduces TI, which is an important problem for the tourism industry. The study results show that SEL was negatively related to workplace ostracism (WO) and work alienation (WA) and TI. Further, the findings show the serial mediating effect of WO and WA between SEL and TI. The study makes useful recommendations to managers to eliminate ostracism, curb the feeling of alienation and decrease TI.
