I suppose it boils down to .. for me .. I worked prevailing jobs for over 10 years had benefits, retirement and could stop the clock when I got home.
I drove 2 hours in traffic both ways for an 8 hr. days wage. I really had no tax write offs and had to work many 10 - 12+ days some of which where graveyard shifts, when being a foreman for 2.00 more, I grossed on the take home pay 38.00 hr and the other 30.00 per hour went to benefits which I never really used. I didn't like the fact that I had to jump when told to jump or eat when told to eat, not a rebel just a person with better horizons I suppose. Oh .. and when work ended many times you got a pink slip and told to collect unemployment while waiting for your number, 1 year later I said enough.
As a independent I make about the same if not more, I work hours into the night researching supplies for bids or design, I drive maybe 15 minutes to various projects in my community, I get incredible tax write offs as an Inc. I have a lot of freedom, I can only blame myself for not working.
So I suppose aside from the money aspect, those electricians wondering what's the best route, its really only a decision they should weigh out, the pro's and cons.
I chose Independent, don't like the politics of prevailing wage with their last hired /first fired ways. Besides I'm getting pretty old to compete
with the energy of 25 year olds.
