I'm not sure what you're asking here mate?
Clearly a contract of this type is not aimed at you: It's aimed at minimum wage workers in cities, who will do pretty much anything at the lower end of the wage scale. Company A needs 10 people for a shift at Generic Fast Food Restaurant, they call 20 people the day before telling them to come in, 5 don't bother showing up but 15 do. They employ the first 10 to arrive, the other 5 get sent home.
In that case why has every media made it such a Major Election issue.
