If this is all a head-on to Marten going back to school, I quite approve. He could use something to do, story-wise.
That said, a lot of this is really pretty at odds with my experience with the world. I know academia can be kind of weird, and maybe this is a case of it, but...
- while there may be certain very specific careers with hard educational requirements (e.g. medical doctors), it's really quite unremarkable in my experience for people to wind up in fields for which they lacked the formal qualifications.
- In my experience, once you're in, you're *in*. People voluntarily leave jobs for all sorts of reasons, but generally are only involuntarily separated for poor performance or budgetary reasons. Someone whose been in a job for years getting let go because a more qualified candidate happened along would seem truly remarkable to me.
- In general, while highest degree completed informs a person's salary since that's just how it works, once one is hired, people stop caring too much about the paper and start caring far more about a professional knowledge, skills and abilities. Admittedly this I can see academia being a bit different about. But using myself as an example, my being a chemist by education (vs mathematician, physicist or engineer) is more "weird trivia" within my workgroup than something that has *any* impact on my work or future employability within my specific field. My 15 years of experience is *vastly* more important that my educational misalignment.
YMMV, and all that jazz. Expect seriously, if anyone ever finds themselves looking for a job, don't be afraid to apply for ones that seem interesting but you lack the paper qualifications for.
