Nowadays, Human Resource (HR) practices can motivate employees to stay committed. The purpose of this paper is to provide insights into utilizing the capabilities of the workforce in the telecommunication sector to ensure an effective and committed workforce in the future. For the purpose of collecting the data, a survey was conducted among employees in one of the telecom companies. The study was conducted in the Delhi NCR region of India. There were 125 valid responses to the questionnaire from the sample size of 220 employees at Bharti Airtel. In order to analyze the data, a multiple regression technique was used.
