If there is no late coming policy for the organization, please frame the same or if there is certified standing orders- there may be clause for late coming. Usually most of the organizations have system of 10 minutes late is allowed. If there is more than 10 minutes late then it may be one day leave adjustment against 3 days late coming or deduct salary for the minutes of late coming. Maximum 3 to 5 days late coming in a month is allowed and beyond that the employee should not be allowed to join for duty.
Please immediately issue one strong warning letter stating regular late coming and the rule for late coming. Even after all these if the employee has not been corrected, then issue show cause / charge sheet. After enquiry findings provide him punishment proportionate to the gravity of misconduct ( may be 4 days suspension without pay ). Hope the employee will correct himself by this time and if not issue 2nd show cause or chargesheet, conduct DE and follow all PNJ and then terminate his job.
