Hi Nina
I'll divide yr query in to two parts,
(one) deduction of employees share is legal?
Yes, according to EPF Act employer has to deduct EMPLOYEE'S share from pay.
(Second) Can employer deduct employer's contribution from pay?
No, employer cannot deduct EMPLOYER'S CONTRIBUTION from pay whether employee is on probation or Temp. basis or Permanant. It is the violation of the Act. Pl refer Section 31 of EPF Scheme 1952
Hope this will be clear your confusion
Regrds,
