Hi,

Even if the employee had created fake email id you are not supposed to terminate the employee directly and was supposed to follow proper disciplinary process right from issue of show cause notice followed by domestic enquiry. It looks like your employee created email id using gmail only. What was the intention of the employee and in what way it is against the policy of the Company.

You haven't heard the explanation of the employee and opportunity was not provided to the employee to defend his case. In the absence of proper disciplinary process employee has the right to demand his salary.

In continuation to what Mr Lakshmi Narayan has rightly said, I would say that it is fine if you close the matter by paying him the salary due to him for the days he worked. When you wish to lodge a case against him now, you should have done it before you dismissed him. Therefore, pay him whatever is due to him, deducting whatever statutory deductions are to be made like PF, TDS etc so that it could be an evidence that he had a very short period with you and it could also help you when a background verification is made by his prospective employer.
