Um, you might try reading the story.
You just might use some common sense in reading the story: They are ONLY laying off non-union workers. Not union workers.
Why? The reason is very simple: the communistic union workers control the company by intimidation, both physical and legal while the non-union workers have no control at all...and should not in a free country.
Simply put, it was cheaper to lay off non-union workers than to bear the expense of fighting the unions (and their illegal tactics) to get rid of them or to lower their pay to save the company.
