Hi,
I, second, Saji would request you to share more details about it
And I feel you need to know more about Termination and its procedure which can help you in getting the answer of your own question.
Second, if you want to discuss about "Separation" so I would like to say that there are many things which come under "Separation" including Termination, Retrenchment, Absconding and Resignations but with TERMINATION only , there are a procedure where employer has to take direct and immediate action against the employee based on a specific or defined terms and conditions of employment when employee found guilty or I would say "because of some wrongful actions of employee, forced employer to adopt this procedure" means the employee been "discharged", "dismissed", "fired" or "permanently laid off"
The employee who's gonna terminate based on valid reasons and after completing procedure and formalities deserves the action and set an example for other employee too, so I dont think professionally we need to think or care about the effects of termination to other employees or about the employee who found guilty in that case.
-RETRENCHMENTS/LAYOFF which hurts employees is an unavoidable/ unwanted situation and neither employee nor employer wants this actually.
-RESIGNATION where employee leave company/organisation with a mutual agreement by following terms and conditions of employment
-and because of ABSCONDING where an employee leaves his job without resigning and informing employer which hurts employer as its increase the attrition (Attrition refers to the loss of employees) comes separation including termination as stated above.
