Employment Contracts and the Contract Act 1872
Employment too is a contract and is subject to the provisions of the Contract Act 1872. A contract is binding on the parties if the terms are accepted by them without any coercion. So, the question is whether an employment contract that stipulates a clause more favorable to the employer is enforceable? I do not envisage any problem with this if the said clause is accepted by the employee of his own free will.
Termination Clauses and HR Norms
Your statement that you want a favorable clause on termination but don't want to do anything against HR norms made me stretch the discussion beyond the sphere of the contract. I examined whether there is any employment law governing the same issue and, if so, whether it impacts such a clause.
Shops and Establishments Act
Normally, the Shops and Establishments Act of the States contains a clause on termination which requires an employer to give notice of a certain time (usually 30 days) to an employee in case of terminating his services. It is prudent to keep the termination clauses in tune with that in the Shops and Establishments Act to avoid any conflict. So, please check the Shops Act of your State if your establishment is covered by the said Act.
