My sister who also goes to uni, works at a call centre. It's a 2 minute walk from central station. She gets paid $17.81 per hour I think but you have to work a minimum of 20hours per week and you get paid fortnightly. All you have to do is call people and ask them if they'd like to donate money to various organisations/charities. It is simple, but from what my sister says, the environment is extremely depressing.
