I work under a contract that says my employer claims a non exclusive right to use anything I invent that could be construed as using company resources. It’s not an unfair contract, and I obviously don’t use company resources for anything I do on my own time, but the funny thing is that if they ever decided I had inadvertently used some company resource for some part of a personal project, it wouldn’t matter. I license my personal projects CC0 aka public domain. Everyone has a non exclusive right to use my work!
