Well, yes, there are whiny teachers just like there are whiny folks in any line of work, but I don't think that the teacher who is the subject of this thread is one of them, at least not in the context that we saw.
I don't think that she stood up and complained about teachers having it rough compared to other workers in other jobs; she complained to her board that funding a substantial pay raise for the Superintendent while simultaneously withholding ALL pay raises for district teaching staff (regardless of individual merit) was poor use of limited district personnel funds. I don't know if she was herself eligible for a raise had one been on the table for teachers, but the board crying poverty and claiming that it had no money available for pay increases to teaching staff for an entire 10 yr period was obviously disingenuous, if they could come up with the cash to to give, in one year, a raise to the superintendent that was equivalent to the annual salary of an entry-level teacher.
It really doesn't matter if other professions have difficult working conditions and low pay; what's in question here is whether a teacher in that district had a legitimate complaint to take to the board regarding poor stewardship of public funds. If the financial situation is actually how she described it, then I think that she certainly did, and furthermore, any resident of the district would have had grounds to raise the same point.
Administrative bloat is a real problem in public education at all levels, and I can say that, because it's the profession I'm in. I'm an administrator, and my work is needed for accreditation, but I don't teach. I'm in higher ed, not K-12, but we have the problem on an even greater scale: schools are over-relying on adjunct faculty and claiming that they cannot afford to hire full-time instructors while at the same time hiring more and more full-time staff in administrative positions (though not usually in my field; you see it more in Admissions, Finance, and Development, especially.)
