Buddy,
Provident Fund (PF) is common for employees. Whether he/she earns 1000 or in Lacs PF has to be deducted. It is a LAW.
PF is not calculated according to greater or lesser Basic pay. But, 12% (standard rate) is deducted from Basic+DA (Dearness Allowance).
"Bonus" is under the discretion of the management to give or not and it is not compulsory as per law.
Then I do not understand what do you mean by "Employee Share".
PF is compulsory and no one can avoid it. Even if he/she is a contract or full time employee, why even Chairman of a company, PF has to be deducted from their salary. Whether your family member is interested or not PF has to be deducted.
