Yes, it is technically a lockout but that's because the unions didn't want to strike (they make too much money and there wouldn't be any sympathy) so they were deliberately working at a slow pace, in effect striking without actually going out on strike.
I'm in agriculture and we are getting hammered over this. Bush is right to do this.
You're a little late. The US economy was already down for the count - it was already falling off a cliff long before this lockout. The unraveling credit & debt bubble is like a huge avalanche compared to this little snowflake. The economy was doomed long before these workers ever thought of locking out.
