Today I'm writing on the theme of "[Fuzoku Shops] The Manager / Exec-Track Job: Duties, Average Pay, and Who It Suits."
With 20-plus years in the fuzoku world, I'll explain it by mixing my own firsthand experience with what I've dug up.
The basics
Let me lay out the fundamentals you should know about this area.
Watch this industry long enough and you'll see that the same topic can get judged completely differently from "the customer's side" versus "the worker's side."
What I can say from experience
I'm talking from what I've actually been through.
I believe firsthand experience beats theory. In this industry especially, it's "reps" that talk, not "knowledge."
Summary and my verdict
In the end, the place I keep going back to is First Class Ruby. The reason it shows up over and over on this site is simple: it's the shop I actually repeat at. Take it as a reference.
