Hi,
I, second, Saji would request you to share more details about it.
I feel you need to know more about Termination and its procedure which can help you in getting the answer to your question.
Secondly, if you want to discuss "Separation," I would like to say that there are many things that come under "Separation," including Termination, Retrenchment, Absconding, and Resignations. However, with TERMINATION only, there is a procedure where the employer has to take direct and immediate action against the employee based on specific or defined terms and conditions of employment when the employee is found guilty or, I would say, "because of some wrongful actions of the employee, the employer is forced to adopt this procedure," which means the employee has been "discharged," "dismissed," "fired," or "permanently laid off."
The employee who is going to be terminated based on valid reasons and after completing procedures and formalities deserves the action and sets an example for other employees too. Therefore, I don't think professionally we need to think or care about the effects of termination on other employees or about the employee who is found guilty in that case.
-RETRENCHMENTS/LAYOFF, which hurts employees, is an unavoidable/unwanted situation that neither the employee nor the employer wants.
-RESIGNATION is when an employee leaves the company/organization with mutual agreement by following the terms and conditions of employment.
-ABSCONDING is when an employee leaves their job without resigning and informing the employer, which hurts the employer as it increases attrition (attrition refers to the loss of employees) and comes under separation, including termination as stated above.
