Fisher Industries Home
One more I forgot to add was anything to do with aggregates like gravel, asphalt, concrete and the machinery that produces this stuff. This is a HUGE growth industry. The link above had a large billboard in front of thier factory looking for welders. Welders seem to be the highest in demand. I assume the competition is so fierce that the pay has to be rising very fast. You don't like where you work, you can quit at 9:00 AM and have a new job by lunch time. I'm not making this up.
Just because they don't list a job on thier web site doesn't mean they are not hiring. Word of mouth is how trades get filled lots of times and they offer cash bonuses if you refer someone and they stay for a certain period of time. Many companies do this.
