Basically employment is a contractual relationship between the employer and the employee and as such the mutual rights and obligations of them arise only from the terms of the contract of employment. Thus any breach by anyone of the parties to the contract is a subject matter of the Indian Contract Act,1872 and as such the forum for redressal is the Civil Court. But, Industrial Disputes Act,1947 is a special enactment for the purpose of investigation and settlement of industrial disputes.Therefore, despite being the off-shoot of the Law of Contract, the ID Act,1947 is designed in such a way to modify the existing contract between the persons covered under the Act viz the employer and the workmen so as to ensure industrial peace and amity.If you analyse the definition of the term "workman" u/s 2(s) of the ID Act,1947, you will find that any person employed mainly in managerial or administrative capacity is not a workman. Thus it is the intention of the Legislature to keep off those who escape the ambit of the definition of workman from the application of the Act. Once any employed person is not a workman as defined under the ID Act,1947, he cannot have recourse under the ID Act against his/her alleged illegal termination and if any claim is filed in this regard under the Act, s/he has to prove that s/he falls within the seven inclusive positions of the definition clause else the claim would just be dismissed in limine. The special power of the Tribunal under the Act is that it can not only set aside the order of termination but also order reinstatement with back wages and other attendant benefits whereas the Civil Court can set aside the orders of termination and award damages only.
Moreover, one can not expect judicial precedents for every aspect of employment and therefore, in case of a person not being a workman under the Act, he has to just work out the remedy for his employment grievances by his/her common understanding only.
