Gazoo, I like you come from a long line of union members, but there's a big difference between unions. Your trying to apply National Labor Relations Act laws to a Railway Labor Act field. They are not the same.
From Wiki:
"The
Railway Labor Act bans strikes by United States airline and railroad employees except in narrowly defined circumstances. The
National Labor Relations Act generally permits strikes, but provides a mechanism to enjoin strikes in industries in which a strike would create a national emergency. The federal government most recently invoked these statutory provisions to obtain an injunction requiring the
International Longshore and Warehouse Union return to work in 2002 after having been locked out by the employer group, the Pacific Maritime Association. Some jurisdictions prohibit all strikes by public employees, under laws such as the "
Taylor Law" in
New York. Other jurisdictions impose strike bans only on certain categories of workers, particularly those regarded as critical to society:
police and
firefighters are among the groups commonly barred from striking in these jurisdictions. Some states, such as
New Jersey,
Michigan,
Iowa or
Florida, do not allow teachers in public schools to strike. Workers have sometimes circumvented these restrictions by falsely claiming inability to work due to illness — this is sometimes called a "sickout" or "blue flu", the latter receiving its name from the uniforms worn by police officers, who are traditionally prohibited from striking. The term "red flu" has sometimes been used to describe this action when undertaken by firefighters."
If you don't buy that, then read this.

Short version you can NOT interrupt interstate commerce, in any way, without it first being approved by the NMB and government.
