Termination because of use of generating leads through social media

Can a company terminate his employee on the ground of the employee using different brand names for generating leads on solar media such as Facebook?

Depends on the service conditions / code of conduct (ethics) governing all employees.

Please rephrase the question to understand it better.

Please give sufficient information.
Who was terminated, when he/ she was terminated, why he/ she was terminated, what are the service rules that give information about termination, whether employee was given any show cause before termination, whether any domestic enquiry was conducted before termination, designation of the employee and so on.
Unless we know the complete facts of the case, no further suggestions can be given.

I think that the question is put up on behalf of the management. Even otherwise the answer remains the same as given by the above learned members.
