I'm a software-developer, and I've had a list of project ideas that I've had floating in my head for a couple of years now. I also have a co-worker whose work-ethic I respect, as well as their programming ability and ability to learn. Neither of us work full-time for the company.
The projects I have in my head are in no way in competition to a product that our company produces, and I don't think would have any interest in developing in the future-- within any reasonable consideration, anyway. Not like it would be impossible for them too, just seems highly unlikely.
My question is, is it ethical for me to ask for help, or to enlist him on any of these projects seeing as I met him through work, and potentially start a business/service/etc.. on the side?
