"I can't ever imagine white collared IT workers joining any union. "
This train of thoughts is - amongst other things - what brought the country that we live in where it is now, which is not a good place.
Automotive engineers' unions. Junior doctors' (as they call them in the UK) unions. A ton of "white collared" folks unionized all over Europe. With real power. In countries whose standard of living often surpasses our own. Is the life perfect over there? Far from it. But let's not be blind to the world that is surrounding us. We might be able to learn something and improve our own existence.
"The salaried, educated, trained, skilled IT and salaried whatever do not worry in the least about being released from the company. "
I'd highly question this line of thinking. Salaries in the IT world have gone down tremendously over the past 10-15 years due to market being somewhat saturated as well as to overall economy being in the toilet allowing companies to blackmail their potential new hires. Not to even touch the entire H1B scam that has gotten so popular over the last few years. There are some people still making serious amounts of money in this game, but nowhere near where it was at Y2K. Not by a long stretch.
