Dear Indu,
Yours is a very pertinent question focusing on the genuine difficulties experienced by employers at times due to the job-hopping done by certain indecisive employees. Therefore, there can be no generalization putting the blame entirely either on the employer or on the employee concerned. A situational perspective, coupled with the aspects of legal compliance and feasibility of performance, has to be adopted on a case-by-case basis. In fact, the various case laws in India so far on the subject matter of employment agreements requiring employees to serve a certain predetermined number of years in the establishment after induction, failing which to pay liquidated damages to the affected employer, are based on this principle.
Employment is always at will only.
One of the reasons for fixing the period of probation in the contract of employment emanates from this universally accepted concept, notwithstanding the nature of parameters associated with it. If the employee falls short of the expectations and assessment of the employer in terms of behavior and performance during the probation period, the employer can terminate his services without assigning any reason, with or without notice, as per the unilateral exit clause which is called "discharge simpliciter," that is devoid of any stigma. Such an equal right is given to the probationer too if he is not satisfied with the work culture of the organization, or career prospects, or even the later availability of a far better offer from elsewhere, or any other compelling personal reasons.
The objective of an employment agreement imposing a compulsory service period
The objective of an employment agreement imposing a compulsory service period after confirmation and the levy of a penalty in case of breach by the employee is only to discourage the tendency to switch jobs after acquiring sufficient experience. However, the quantum of damages should be reasonable, i.e., commensurate with the cost of recruitment and the cost of time, energy, and money spent on imparting training to the employee. That's why such employment agreements are held to be enforceable, subject to the reasonableness of the terms and conditions, as there can be no lifetime contracts of employment.
At the same time, Indu, you will agree with me that if the recruitment process is effective, one will get the right employee who will stay long. If the intent is employee retention for a considerably longer duration, the employer should devise his employee retention policy in such a way that trained employees do not leave their jobs for the sake of temporary monetary benefits.
Since Dr. Sivakumar has explained the unfair tactics actually adopted by both some employers and employees in this matter, I avoid going further in this regard.
If the reasons for exit are genuine, both the employer and the employee should be prepared to fulfill the exit conditions and strive to make the separation formal, friendly, and peaceful by making mutual adjustments. What's the guarantee - the same employee may come back to you in the future, or you may require his services once again for a higher position.
