I've worked at 7 GM plants, all union. The only time I had long breaks was because management was bad at managing time. I can't think of a time I had a long break because of the union. Why would you have a long break because of the union? The union got us two 20 minute breaks and a half an hour lunch. If you call that long, then blame it on the union. Just like any other job, it's the boss who has to do the work to get the slackers back to work when the break is over.... Like I said, there's a lot wrong with the unions, but long breaks are managements problem....
