Do you have a separate department to which all employees who do not follow the company policies and who are problematic can be transferred???? Do you think that in the new department he will perform well? No. This is a wrong selection. It should be rectified immediately,otherwise, you will not have a pleasant sleep. How to correct the mistake in selection. Here is the significance of Probation period and the wording in that. Probation is a period during which an employee can be evaluated as to his fitness to the culture of the organisation and if he is not fit terminate him without showing any reason and without giving any notice. If there is any notice required,you can give, but you need not explain why is he terminated. If you say something or some reason for termination, he should be given an opportunity to defend the charges, otherwise, the termination will cause stigma. Therefore, you can quote the clause in the appointment order and send him out at the earliest.
