How is the maintenance treatment of Air Macau?

At Macau Airport, there are basically only Qantas and Mintel ground crew, mostly mainlanders and Filipinos, and only a few locals. As far as I know, the driver's salary is about 14000 yuan, ten days paid vacation, five days paid sick leave, one or two days off, free medical treatment (minor illness), 24-hour shift, and the housing subsidy is similar to Qantas. You can't get residency.
