I agree that if an employee is a member of the Fund, then he/she should continue to remain a member until he/she withdraws the money in his/her name from the Fund or is excluded from the Scheme. As you have mentioned that the employer-employee relationship is not extinguished on suspension, I do not agree with you on this point. There is an order of APFC-EPFO in which it is clearly mentioned that "during the suspension period, the concerned workers are not on duty, and the employer-employee relationship is suspended."
Subsistence Allowance and Provident Fund
Subsistence allowance is paid for the survival of the suspended workers, and during the suspension period, the concerned workers are not on duty, and the employer-employee relationship is suspended, since the decision does not arise from the inquiry. Hence, subsistence allowances paid to the suspended employees do not constitute wages and are not liable for deduction of Provident Fund.
For your ready reference, here I am attaching The Order dated 17-11-2009 passed by APFC, RO-Mumbai.
