My employer is willing to completely pay for an MBA, but it's from a rather unimpressive school. To give you an idea, the program is not accredited (they're working on IACBE), the overall university is ranked something like 11th for regional universities, and it's undergrad admit rate is around 80%. It's not a diploma mill, but it's just a small, private school.
As far as my career goes, I'm in STEM research management and I have no interest in, nor would I be good at, a high-powered job. I'm not going to be making $400k+/yr. My employer is truly giving me the option and there are no repercussions if I do not do this. However, I do not plan on staying with my current employer forever. If you were in this situation, what would you do?
