In the modern world, businesses operate in a very competitive and constantly changing environment. Therefore, organisations need to have highly skilled and dedicated personnel. Therefore, any company must address the demands that foster employee dedication. Organisational commitment refers to the psychological attachment that employees form with their organisation. Given the paucity of research on the organisational commitment of employees in the telecom sector, the present study focused on filling that gap. The study aimed to explore the levels of organisational commitment of telecom sector employees in Kerala. It also aimed to investigate the association of age and work experience with organisational commitment in the telecom sector. The study was conducted based on primary data collected from the employees working in Jio and BSNL using the structured questionnaire. The study found that employees have moderate levels of affective commitment and lower levels of normative and continuance commitment. Employees’ overall organizational commitment is recorded at a moderate level. The study also noted significant differences in organisational commitment among employees in different age groups and employees with different years of work experience. Commitment increases as age increases and experience increases. The study has implications for recruiting employees and formulating practices for service excellence.
