I googled "union vs non-union wages automakers"
Here is one of the articles:
********newsbusters.org/node/7344
According to this Wall Street Journal article reprinted in the Star-Telegram, "on average, GM pays $81.18 an hour in wages and benefits to U.S. hourly workers, including pension and retiree medical costs."
But in his vituperative rant against the Big Three U.S. automakers, Boston Globe columnist Derrick Z. Jackson manages to ignore the huge labor cost advantage enjoyed by non-union Toyota.
How much of an advantage? According to that same article, "Harbour Consulting President Ron Harbour estimates Toyota's total hourly U.S. labor costs, with benefits, at about $35 an hour." That's right, GM's average labor costs are 130% higher than that of the US operations of its Japanese rival. That translates into a $1,000/vehicle average labor-cost advantage enjoyed by Toyota. Thank you, UAW!
