"Increased competition with untrained, unsafe, Non Union Scabs"
If they are so untrained and unsafe why do you have a problem with having to compete with them?
And your term Scabs is quite revealing. I once personally witnessed a 20 year old girl who was so excited to find work at 25$/hour (late 80's) during a UAW strike. I was a young newly graduated brilliant engineer making 17.50$/hour (the prevailing wage for a non-union engineer). The union labor started out with not even a high school diploma or any training at 35$/hour and quickly rose to 90$/hour. Unbelievable benefits to boot. Average wage when contracts were bid for the union labor was 60$/hr. And don't get me started on their work habits and job duties!!!
