Tradies will seldom be able to make switch to "office work" outside of smaller family owned industrial companies where the alpha male sorta mentality still reigns.
I've not only watched it happen to others, but I've experienced it myself. You learn an industry inside and out, higher ups notice you're not a retard and offer you a position in operations or admin. It sounds awesome and you eagerly tackle the challenges before you, anxious to make an impact, right wrongs, improve processes, save money and make the entire place better, then...you start going to meetings.
You realize that your peers and superiors are all playing a game you don't understand. You legitimately believed that they were working to make the place better, more profitable, but, they're not.
Then you realize, you weren't actually selected because you're smart, you were selected because they considered you a pushover who (retardedly) cared about doing a good job. They don't care; that's the joke of the game you haven't picked up on yet. They only care about appealing to others, collecting a bigger check, and bailing at the first sign of trouble.
Then, you eventually blow up on someone because you cannot grasp the game being played. You keep telling yourself: no, these people are just trying to get along and make decisions via committee, it's hard, but they're probably still good people.
They are not, and your down home sympathy for the working man had rendered you an outcast. It's like trying to make the switch between inmate and prison guard. It seldom works out well.
