Dear Lakshmi,
First of all, please learn the scope, definition, and applicability of terms like termination and suspension under the ambit of statutory laws applicable in your area.
Secondly, termination is a negative and adverse event in anyone's career, which is seldom used even in large and reputed industries. This should be applied with a lot of process and procedures that come only with years of experience and instances accumulated over time. Are you armed with this?
What is your authority in dealing with situations like this? Is it assumed or clearly written down in your functions and responsibilities? There are many senior and competent managers, workers, and staff well past 65 years working across various industries with better contributions, for example, ex-defense employees.
You need to have the top management's active role and contribution when dealing with senior employees based on age, authority, and competency. Otherwise, you will land in trouble and put the company in difficulties that are hard to resolve later. Take a smart, cautious, and, more importantly, sensible step. At best, consider the contribution, physical and mental strength, and how they overshadow their age; you need not worry at all. What support do you get from management in this case?
