I am considering to quit the company I work for in the coming months.
Through the years of my employment in the subject company, I have gained several diplomas and certifications, such as user/instructor licences on the operation of specific technological products. I refer to diplomas and certifications awarded from outside the company, not internal ones.
Most of these certifications have my name on it (not mentioning the Company) though clearly it was the Company paying/requesting the respective training.
The question is, legally and ethically, should I request/demand the originals of these certifications to use it in the next opportunities? To who they belong; to me whose name is on the diplomas (while not having paid one cent for them), or the company that bought the actual training services that led to the certifications?
P.S. You might ask why would the company want to keep these documents after I leave. Let's just suppose they will and they might just say something silly, such as they don't remember where they keep the files as an excuse.
