depends
casual for casual you will get the most I highly recommend this form of employment contract as you will get paid the most!!!
Unless your a fucking total drop out failure who has wasted your parents money and time you should then fucking just quit life.
Or you could go full time max you can get at maccers at 18 is barely $15 they will fucking pay you minimum wage and treat you like shit you wont be taken seriously and get laughed at by all your friends cause your 18 and you work at mcdonalds
Anyway I think they will not even consider employing you as 18 is pretty old they might as well pay some 14 year old $5 for the same input.
So basically your screwed why didnt you pay attention when you were at school? or befriend that fatkid and ask for his notes
its too late now badboy
herp a derp
