You can of course terminate the service of a staff by giving the necessary notice or payment of indemnity in lieu of notice. But you must a valid reasons to terminate a staff even under probation. The staff has the right to complain if the termination is unfair.

 Dear Administrator,

Thank you for the reply.

A few question :

1. Should we mention the reason to terminate in the letter?

2. Should we place the calculation of indemnity in lieu? Is the staff under probation entitled for the termination benefits?

3. The termination is due to the misconduct, may we proceed with termination without giving the warning or show cause letter?

In all such cases, I think it would be better to give a chance for the employee to explain themselves. In this regard, hold a domestic inquiry and then decide what to do with him. Read up section 14 of the Employment Act on holding inquiry and the Employment(Termination and Layoff Benefits)Regulations about payment of termination benefits.
