Hi there, I have been employed at my current workplace since July 2015. In my employment contract, I agreed to 4 weeks notice. I signed the contract when I started work. About 4 months into the role, the GM came to my desk and got me to sign an amended document changing the terms to 12 weeks. I was not given the option to take the document away and I felt pressured to sign on the spot, which I did. I was not given a copy of the amended terms. Today, I have resigned from the position and have offered to give 6 weeks leave. My employer has refused to ask me to work the full term. Can I get out of the 12 weeks? What will happen if I only work the 6 weeks? I have only 1 or 2 leave days owing which I am more than happy to forfeit. Can I be sued based on the amended contract under Contract Law? Any help would be greatly appreciated before I fight the notice period. Thank you!
