I think, the employers do not have the right to with hold PF amount. It is true that they do not process PF until and unless you do not give a proper notice period or break a bond.
But this is absolutely wrong. My PF is not yet transferred from mm previous employer and its almost 3 years now. PF control should not be in the hands of the employers.
There should be a unique PF account per individual and all contributions should be made to that particular account.
If you switch, you only need to give your Permanent PF account no. like (PAN) and money should get deposited there.
No HR or companies dependency ......
Can't understand why everytime a new PF account is created for new employers.
