The demonization of unions through corporate money and propaganda is a story of the decline of the middle class. When you don't defend each other soon you lose. When you can turn people against each other you control them. An excellent history below for the interested reader.
"With all their faults, trade unions have done more for humanity than any other organization of men that ever existed." Clarence Darrow
"Historian Phillips-Fein traces the hidden history of the Reagan revolution to a coterie of business executives, including General Electric official and Reagan mentor Lemuel Boulware, who saw labor unions, government regulation, high taxes and welfare spending as dire threats to their profits and power. From the 1930s onward, the author argues, they provided the money, organization and fervor for a decades-long war against New Deal liberalism—funding campaigns, think tanks, magazines and lobbying groups, and indoctrinating employees in the virtues of unfettered capitalism."

American unions
Unions are (basically) Evil
"Corporate propaganda directed outwards, that is, to the public at large, has two main objectives: to identify the free enterprise system in popular consciousness with every cherished value, and to identify interventionist governments and strong unions (the only agencies capable of checking a complete domination of society by corporations) with tyranny, oppression and even subversion. The techniques used to achieve these results are variously called 'public relations', 'corporate communications' and 'economic education'." Alex Carey 'Taking the Risk out of Democracy'
