I still consider myself a learner and young, even though I find that I have far more and longer experience than your 23 years in a Maharatna PSU with more employees than you quoted. Each unit of the organization has city-sized townships attached to its plants and more unions than you mentioned. I hope, being an experienced person, you can guess and comprehend the complete picture.
However, let this not be taken into consideration, and I seldom mention this, for I do not wish to be known as "old," with rigid ideas and unable to see the other side of any argument or concept. Anyway, I have put forth my opinion, and I do not wish to "personalize" this issue. There are several sayings, full of wisdom, against arguing with others, and I subscribe to those pearls of wisdom.
In any case, I agree with whatever you say, as it may be in the terms and conditions of your company. I also know for a fact that many small family-run outfits, registered as companies, routinely engage in such exploitative practices to save money. They also indulge in bifurcating the minimum wages to reduce their contribution to P.F. They do not give gratuity if an employee does not complete more than 5 calendar years in service; they club all the weekly offs or holidays during, before, or after the leave period, thus depleting the employee's leave balance, etc.
However, what we are discussing here are the best practices, which are "not bad" in the eyes of the law and natural justice and can stand the scrutiny of a court of law as being fair to the employee and impartial.
I shall once again quote from you to convey what I intend to:
"By virtue of the clause in the offer of appointment (three months' notice by either party or salary in lieu thereof), any party willing to terminate the contract is legally responsible/bound to give three months' advance notice (or salary in place of notice period). In other words, the other party has a legal right to receive either notice or salary in lieu thereof."
Likewise, when an employment contract is intended to be terminated by the employer, it is his legal responsibility, necessary and essential condition (by virtue of the termination clause in the agreement) to give three months' notice or salary in lieu of notice. In this case, it is the legal right of the employee to get such notice or salary in lieu thereof, whatever the employer is willing to offer. The employer cannot remove an employee unless either he gives three months' notice (allows the employee to serve for three months) or pays salary for the notice period.
Please understand that the moment the employer decides to remove an employee (earlier than the agreed-upon notice period of 3 months), on its own, suo moto, without the willing consent of the employee, your paragraph becomes effective -
The employer cannot remove an employee unless either he gives three months' notice (allows the employee to serve for three months) or pays salary for the notice period.
This is what I intended to convey! The employer can send him packing the next day, but in that case, it also becomes his liability to pay the notice pay.
Warm regards.
