What’s Behind the Decline of Unions in Manufacturing? | Industry Market Trends:
"Union proponents view the hiring of anti-union consultants and similar actions by employers as “union busting” tactics that deprive workers of having a voice at the workplace.
A 2011 study by Cornell’s Bronfenbrenner and Dorian Warren, an assistant professor of political science at Columbia University, found that:
Employers required workers to attend “captive audience meetings” with management in 89 percent of the campaigns started by unions to organize the workforce;
Workers are threatened with plant closings in 57 percent of the union campaigns and with loss of wages and benefits in 47 percent;
In 64 percent of the campaigns, workers are interrogated about how they and other workers intend to vote.
“The data show that employer campaigns against union certification elections begin much earlier than expected and continues all the way up to the election,” the researchers concluded."
