Hmm. I was offered a VP / marketing gig at a tech company once and in the course of negotiations, I put in writing, just as a formality, that I regarded miles & points earned while in the company's employ as mine. I stepped on a real land mine... the CEO became very emotional and defensive and started to raise her voice about how fair, very fair, they were to all their team members, their family, and how could I make an issue out of something as small as that... etc...

Canary in a coal mine, indeed. I didn't take the job. The guy who did lasted 60 days and fled, telling me later that the work culture was completely invasive, emotionalized and insane. The company collapsed.
