Dear Hema,
The term "resignation" in an employment context refers to the voluntary relinquishment of his/her post in an organization by an employee for some personal reasons. Therefore, the employer has naturally no role in that except accepting it or rejecting it based on certain reasons permitted in law.
On the contrary, when the employer compels an employee to exercise this option against his willingness and he does so, later, if agitated and proved in a Court of Law, it would be treated as an unfair labor practice and end up in reinstatement of the employee with attendant benefits or in an award of heavy damages. Yet there cannot be any denial that in exceptional circumstances, such a practice is followed by employers. But they are few and far between.
When matters like trust and confidence or authority or gradual decline in performance of the employee from the employer's perspective become contentious issues between them, resignation by the employee becomes a truce by consensus to avoid the likely mutual damages. The deliberations prior to such resignation go unrecorded only as observed by Mr. Dinesh. Therefore, avoid communication, if any necessary in this regard, in writing.
