Union Busting is a term used by labor organizations, trade unions and others to describe anti-union activities that may be undertaken by employers, their proxies, state and local governments, and in some cases workers, often in response to activities such as picketing, card check, organizing, and/or strike actions.
The colors of the pales (the vertical stripes) are those used in the flag of the United States of America; White signifies purity and innocence, Red, hardiness & valour, and Blue, the color of the Chief (the broad band above the stripes) signifies vigilance, perseverance & justice..
Red represents valor and strength, white represents innocence and purity, and blue represents perseverance and justice. These are the same meanings attributed to the colors of the Great Seal. Other people suggest that the stars symbolize the heavens and the stripes symbolize rays of sunlight.
