I was terminated without cause and no notice due to break down in communication so my boss claims. But he chose to stop speaking to me several months ago

We are sorry that you lost your job especially since the circumstances were so unfair. The employer owes you pay in lieu of notice based on a number of factors, including your age, length of service and the type of job you were doing so please give us a call to discuss the value of your entitlements and the best way to recover them.
