If there is a general strike, it applies to everyone. The unions that initiate these strikes are the camioneros (Moyano) and gastronómicos & hoteleros (Barrionuevo) want to paralyze the country. People who cross the picket lines are subject to threats with guns and roving gangs of mobsters. They usually don't go after people in the street, however if you try to drive a truck or move a train they will come after you and you will get it. So follow the news, if the strike on the 10th is officialized by these guys don't count on being able to do anything that day, unless you have a private car (but roads & tolls may be blocked) or can walk somewhere.
