Hi Nyrie,
My name is Ann-Marie and I am the Online Community Coordinator at BCNA.
You may wish to contact the Cancer Council's Information and Support line on 13 11 20. The Cancer Council can provide support and advice about issues relating to employment, including workplace and legal issues.
There is also quite a lot of information about work, including your rights at work, on the Cancer Council NSW's website. You can find the information here. They also have a booklet called Cancer, Work & You, which might be useful.
