Mr Jeeva is correct, the structure & break up any wages should not be less than the specified minimum wages of the employment (state/center govt).
Salary breakup is being made just to reduce certain liabilities towards (PF, Bonus, PL encashment, Gratuity etc.), moreover it increase cash in hand salary of the individual.
But as per Supreme court decision wages must be as per applicable minimum wages structure.
Even, in some state like TN, minimum wages defined by State Govt differs industry to industry.
@Redak, just asked a breakup and I gave. It is his/her duty to check the minimum wages his/her company follows, before implementing....
