Second union at American Airlines tries to move closer to possible strike

Second union at American seeks step toward strike

DALLAS — The union representing mechanics and other ground workers at American Airlines is asking federal officials to let them take a big step closer toward a possible strike against the nation’s second-largest carrier.

The Transport Workers said Thursday they asked federal mediators to declare a deadlock in their negotiations over a new contract.

If mediators agree to the union’s request, it could start a 30-day “cooling-off” period after which the workers would be able to strike.

The flight attendants’ union at American has made a similar request.
