Consequences of Abscondence from Employment
I think that you missed evaluating the consequences of abscondence from employment. Abscondence from employment is not only a breach of the contract of employment on the part of the employee but also a grave misconduct warranting severe punishment like dismissal.
Every establishment hiring people is basically a venture to achieve its goals through the cooperative endeavor of the people so hired, marked with discipline and sincerity. Discipline includes proper adherence to the rules and regulations of employment too. Of course, no employee can be compelled to continue their services in an establishment against their wishes. They have the freedom to exercise the option according to their convenience. But it is not absolute. The rules of notice for resignation are reasonable restrictions in this regard, and the employee has to abide by them. Payment in lieu of notice cannot be equated to a bribe for wanton transgression.
As mentioned earlier, an absconder cannot take shelter under the notice clause by being prepared to pay off the notice salary to convert their separation into a smooth and lawful process. Still, the employer can reject it and terminate your services as per the legal procedure. In such a situation, it would certainly adversely affect your future employment elsewhere. Entry into and exit out of employment should always be through the proper doors. Think twice before accepting an offer of employment and then joining. In case you find your decision to be wrong later, go out by following the rules of resignation.
