It is a tradition to outsource the maintenance work that involves the cleaning of the workplace and other dirty jobs. That also applies to the messengers. The reason for outsourcing those job positions is the lack of progress. There is no promotion in sight and a maintenance person who mops the floor remains in his job for a long time unless he makes some improvement on himself like going to school again. This kind of outsourcing still persists and the government seems to be at a loss on what to do.
