Re: Wage negotiation
Never hurts to ask for a raise. Given your contribution to the company it seems like that would be fair. The royalties is another issue. Did you create the artwork at the request of the boss? If it was done on company time they own it, but if you can try to negotiate royalties and see if the boss will be amenable to that, but that is kind of unusual in this situation. I have designed and built a lot of machines, made major productivity increases, and designed new products for a few places I have worked, but that was my job, I didn't expect anything but a reasonable raise at some point and maybe a bonus if it was profitable. There is a reason I have been self employed for a lot of years.
