If I rememebr correctly, the minister is referring to reorganising cleaners job. He said, in the old days, when 3 workers are need at $500, after restructuring the job, 1 worker can do 3 workers job, and the worker will get $1500.
If only all employer thinks like him! Long ago, I was complaining about my job scope does not give me room to progress but heavy work load, the boss said there is another portfolio he wants me to take on as well, i.e double portfolio, WITHOUT any pay increase. And at that time, my pay was even lower then the new portfolio's starting pay! I told him to do it himself and resign.
