I told my boss I had an idea for a program that could improve efficiency across much of the business, and he let me build it on company time. In the long term, he wanted to be able to sell it to other companies. However, the program never got implemented due to personnel mismanagement, and I’d rather be able to post it on my github under a free licence so I can use it as a resume item, and at least someone would have the chance to actually use it. It’s all still in my head, and I could write it again if I wanted. If I do, is it illegal to publish it? What if I write it in a different language? Do I need to change the variable names? I did plenty of research and planning on company time to build it, and it’s not like I can research it again, it’s all still in my head.
IANAL but i’m pretty sure that even without an NDA anything you develop on the job is considered IP of the company. However, as long as it’s not a blatant copy paste(a rewrite), it’s hard to legally enforce that because they have to prove damages. Meaning that if they shelfed the idea/program, even if it’s a blatant copy paste they can’t do anything.
They can sack you.
Basically, they won’t bother sueing you unless you end up making millions off it
But at that point the program will likely not even be reminiscent of its original form
