Those of you with long memories may recall when Caterpillar declared war on the UAW, provoking a long, bitter strike in the 1990s (is there any strike that isn’t bitter?). Well, here it comes again, this time seeking the hides of Canadians:

Caterpillar late Sunday locked out about 420 union workers at a train-locomotive plant in London, Ontario, in a sign that the world’s largest maker of construction and mining equipment is still pushing hard for labor-cost savings despite a big recovery in earnings over the past two years.

   You want to know about greed?

Caterpillar’s earnings for the third quarter ended Sept. 30 totaled US$1.14 billion, up 44% from a year earlier.
