agree with kh.
example i quote.
rubbish clearing in hdb was done in buddy buddy system
they introduce a mini dump truck )
now become 1 man job
the one that gets the job had a increament of 2x his salary not because his performance, but because it has become 1 mans job flashed all over the news
1) now, what about the 1 who are no so lucky?
2) if the machine is so useful and can replace the buddy, that means the job load of the lucky one shouldnt increase, than why double his pay?
3) instead of paying the other worker, the company now pay maintainence to run a machine, is it cheaper?
4) buddy buddy system, they can carry / clear away odd object left in the viod deck that the machine cant handle.
