Dear Karthikeyan, Every company has Industrial Standing Orders approved by the labor department. In the standing orders, misconducts are well defined. Please check the standing orders and find out whether downloading a third-party app is considered misconduct. If yes, then the company is empowered to take action against the defaulting employee.
Definition of Misconduct and Domestic Enquiry
Apart from defining misconduct, the company must conduct a domestic enquiry. The enquiry must be conducted as per the procedure, and if the blameworthiness of the employee is established, then only can the company award a suitable punishment, which could include termination from employment.
In your case, did the company conduct a domestic enquiry?
Thanks,
Regards, Dinesh Divekar
