Pf on less then 15000 - when the salary is so low than how can they split into Basic & other heads?

My wife is working in one of the english school since 22 years and she is getting only 6700 rs, salary pm. The EPF was deducted on the Gross salary (appx. 700/) Rs. But now management has change and they have split the gross salary (6700) in to basic and other allowances. Now the EPF is deducting of Rs. 380/- Rs. only. Is it possible to reduce the EPF.
when the salary is so low than how can they split into Basic & other heads?? so what to do?? Actually what should be the EPF on the above salary structurre??
Sanjiv

split of salary/ increment / change of structure is done only after proper discussion between employees and management and HR, and the final draft is done after majority acceptance, if the incident is happening, then it is not with the single person, but for all employees, if they all are dissatisfied, then they can move to labor commissioner and EPFO jointly against the management decision, but as far as our knowledge go, employees are well informed in advance before any change in salary structure,

Dear Sanjiv
As per notification by EPFO followed by courts decision in a well known litigation of G4S vs Regional commissioner of EPFO it has been made clear that the wage structure should be such that the Basic should not be less than the prevailing minimum wages, so in this case the school authorities shall deduct on the Rs. 6700/--.
Please find attached the notification.

Thanks friends for guidance,
Can you provide me the PF/Labour Department notification with clear amount for minimum wages and for PF as well even they are spitting the structure ??

dear @annonymous
minimum wages is state subject and it differs state to state
there are also many category of trades and zones for fixing minimum wages
you can visit your state labor department site for minimum wages scale

Thanks,
But what should be the minimum wages for Fixed salaries teachers working since more than 15 year in the same school??

there are so many court orders on teaching faculty / staff, as their wages days and working hours are not similar to other industry, so their pay-scale is determined by the recognizing board, not the labor commissioer

I have need the circular for non PF Employee
