My wife works as a casual and has been working a minimum 45hrs a week for the last 6 months. Is it right to say that after 37.5hrs worked, you should be paid at overtime rates.

I think you will find this may depend upon the state you are in and whether she signed an employee enterprise contract/agreement or if she is a union member under a collective bargaining agreement.

I suggest she contact her union, state govt labour department or ministry of fair trading who may be able to help further. In my experience casuals get paid a higher rate than fulltime employees but don't qualify for holiday or sick pay. Good luck.

Have a read of this www.wageline.qld.gov.au/casuals/index.html

If you have any further questions, contact DEIR staff.....

It will be in her contract if she has to be.
