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