Did you have a contract? I don't know about every designer but any design work I have done as an employee for a company I had a contract that outlined what would happen. It usually was outlined in the termination clause or something similar.
That being said, no contract then the two above posters are correct, that work is technically not yours and they will ensure you don't take it with you (if they are smart).
I agree. I think the only way a contract helps you is if it explicitly says that you will have ownership (or license) to the work after termination. As an employer this is not something I would be eager to do.
Corporations not only output "product" (be it art, software, hardware, etc.) but they also build, collect, and maintain large amounts of intellectual property. Generally anything devised under their roof (ie, when they are paying you) is their IP.
It's important to recognize that the company
consistently pays you some amount of money for some number of hours per week regardless of what your output is (clearly this may not be sustainable). But, you can count on it.
Some options going forward:
- You may be able to negotiate with the company on your way out to keep the right to some of the content though it is unlikely. It would have to be something that they do not value or is not part of their core business in which case I would question why it was being worked on in the first place. In any case, this type of thing does happen. As a matter of fact, many new companies are spun out of bigger companies with some IP that the founders (hopefully legally) took with them.
- At your next job you might try negotiating ownership going in but be aware that, as an employer, I would be highly skeptical of the motivation. If you are the #1 (insert position here) in your field and are highly sought after the probability goes up.
- Take the work as a freelance. In this case you [likely] will not get paid for the hourly work but will sell the end product. And, depending on the type of license you grant, you may be able to sell this to multiple end customers. This is truly betting on yourself and the swings in your income will be much more variable (hopefully positive!).
Good luck - let us know how it ends up.
