well i think that if they want to stay working casual thats a choice for them. MAM is just a labour hire company, they dont get 6 weeks annual leave, they dont get 15 days sick leave, they dont get cash meal allowances or qantas staff travel benefits.
To earn the money that they get i understand many are only getting 5-6 days off a month and working 140 to 160 hours a month to make a good income. They are only guaranteed 80 hours a month which is not enough for many to live on i understand.
If they want a full time job with a future and promotion they will at least be able to do it in Australia now
