I think that is your problem. I don't stay in companies where I don't feel valued. And anyway you are receiving a salary every month for your work. If you think you should get more, ask for more or move to another place.

For some people security is more important, for it is not. Because I believe that in the current society the companies can fall in few years (Nokia, Canon, ...). My security lies in my knowledge and my skills, and that is something I take with me whereever I am. I recall something I read, it was like this: "A bird is not scared of a branch to break, because it lies his confidence in his skills to fly".
