My question involves employment and labor law for the state of: CA:

Terminated beginning of April 2009. Contract signed with major client for development work in June 2008. Final commission paid upon successful development which occurred around the time I was terminated. Client pays every 15th of the month and they knew they were getting paid the rest of the monies due on May 15th, 2009. From what I have learned under CA labor laws that money is payable and due upon receipt and final payment from client so now they can be penalized for not paying me. In addition, no where does it state in the commission plan that I needed to be employed to get this commission. I am thinking of filing a claim and getting my money back. So far they have not responded to my letters claiming they owe me.

Any advice? I have the sales commission document as well as the document from the client stating they have paid my company to date.

Thanks..
