I use my doctorate every day in every way. Granted I'm not in the field anymore (but in a very real sense I still am - I'm the resident historian where I work), but the organization skills, the time management, the ability to explain, the ability to teach skills, my capacity to teach myself new stuff, knowing the history of what I'm doing and how that matters, the stuff I learned about administration, record keeping, executive skills stuff, the interpersonal stuff, as well as the ability to do things by myself if I have to, and the understanding of how serious even seemingly trivial stuff can end up being, all that comes into play each and every show.
And, oh yeah, if I have to write up a formal complaint, it's done in one.
