I have been with a company for over 3 years, and I have always put the work I do for them in my portfolio. Their company is unrelated to programming. They have known about me having the work I do for them in my portfolio. Today they told me that the work I do for them they own and to remove any all their projects and any reference to their company off my site. The projects I had in my portfolio are were entirely made by me (no team) and it is about 90% of my entire portfolio. If I remove them I mine as well remove my whole portfolio. In my portfolio I am clearly just trying to show examples of my work. Right now my portfolio is open to public but if I put a password on my portfolio and only allow access for potential clients to see it, and it is not public.
Where do I stand legally?
