All People in All Surveys (Australia)

i was hired as a sous chef to help run a restaurant! i took the job at a peliminary rate of 38000.... i do all that is done of me and more i'm always early and i make sure that i am doing the company proud.... i work an extra 6hrs per week for no extra cash.... the bias in my workplace is that they are now hiring people with less experience and they're getting paid more than me!! it makes no sense.... i think i should be geting paid more than people who are suposed to be the people i'm training for this buisness.... not good enough people

When I started this job it was a position consisting only of assisting in the kitchen, washing dishes, food prep and things a like. Since a week ago the chef has left the job resulting in myself taking up the position and still continuing my original duties. There is not one day I leave on my rostered hours, its always at least 2-3 hours over and no overtime. I dont know what to do my manager just dont want to talk to me about it, she just says "you will get quicker."
