There is no regulation about the transportation subsidy. There is no compensation of transportation fee to IDL, no matter what working time.Shuttle bus operation is for operators(DL). But, current we are only few operators using shuttle bus So IDL can use shuttle bus . The taxi fee subsidy to operators is because of different of salary structure with IDL.
If team manager has difficult to arrange OT due to transportation problem, he must highlight it to GM in advance to find out the solutions.
