If it has my name on it, it likely belongs to me. The portion that clearly belongs to the company, are the role, the amount, and my initials (maybe an anonymying number would be better?)

They're welcome to do what they want with that, but once it includes the ability to make inferences about me as an individual, more than the company, it becomes my data. I likely have to choose to share it to meet the terms of the emploment contract, but that doesn't change the appropriate ownership.

Try and apply whatever rules you want to IP the company claims to own? Surely the exact details of some trade secret process also belongs to me and I can do whatever I want with it because I need to know it to fulfill the terms of that same contract right? I can sell it to a 3rd party just 'cause right?
