Remove the incentive to form one. I read once that an employer was asked why his company was union free in an industry full of unions. He said he treated his workers like they had a strong union. If you treat people badly then they are going to think about forming a union to fight back. Intimidation.
What do the colors of the American flag stand for. While the flag's colors did not have a specific meaning at the time, the colors were significant for the Great Seal of 1782. White: Signifies purity and innocence. Red: Signifies valor and bravery. Blue: Signifies Vigilance, perseverance, and justice.
The 50 stars represents the 50 states, the 13 stripes represents the 13 colonies. The white on the flag signifies purity and innocence. The red, for hardiness and courage, and the blue for perseverance and determination. (Some people also say that the red also represents the blood spilled to protect our country and our freedom.)
