A big reason that I can't really work for the man anymore is that I'm unable to filter information. And by filter information, I mean lie and be fake about things. (If you approach me and ask me if I can keep a secret, I will tell you, "No.") Well, can't isn't really the right word, because I can, that has been proven, but it so deeply bruises my soul (for lack of a better word) that I refuse to play that game any longer.
Being a contract worker where I decide which classes to teach, I'm pretty well insulated from the politics of the corporate milieux and exempt from the hellishness of sales and marketing.
Still, the sticky fingers of the white collar environment somtimes catch me, why just last week, I was reprimanded for having spoken about confidential information. What was that information? That a student dropped my class. Why was that confidential? Because it was the HR Director who had dropped the class. (wouldn't want my bad example to be known by the other employees, better try to muzzle the teacher.)
People I'm super wary of: Salesmen of any kind, Human Resources (anyone in the department), Politicians, lawyers, and even closeted people living double lives.
These kinds of jobs/situations require the candidate to lie about things depending on the audience.
I don't do that. And it's nothing about loyalty or integrity, it's just too stressful. So I won't ever make "the big bucks" because I can't "grow up" and reconcile with the man.
And that's just fine with me.
