I think most of the employers process the papers atleast 1-3 months in advance before the superannuation date. However the actual payment would be dated either the last working day or the next date after superannuation. In fact state & central govt./PSU offices issued strict instructions to process F&F atleast 3 months in adv. Hence pvt.firms also should act like this, if they are not doing like this so far. Of course you might have doubt about their attendance/leave a/c etc. This should be computed on assumed attendance and tackled/reworked, if necessary, as per data on the last day in service. In your case, either vice-chairman or any one authorised officer should be asked to approve on the last date, if he/she is not handing over charge before the last day, after proper scrutiny as per laid down procedures/rules applicable.
