OPINION

The appeal taken by the International Federation of Professional and Technical Engineers, AFL-CIO, Local 241 (“the union”) challenged the decision of Lockheed Martin Maritime Systems and Sensors (“Lockheed Martin”) to bring third-party employees into its Moorestown, New Jersey facility to perform approximately 640 hours of Drafter Designer-Electrical work. The union asserted that Lockheed Martin’s action violated the parties’ Collective Bargaining Agreement (“CBA”) and sought to have the dispute submitted to arbitration. Alternatively, in the event it was held that the dispute was not arbitrable per the terms of the CBA, the union argued that Lockheed Martin’s decision to engage subcontractors to perform the work rather than to recall Christopher Vansaghi, a union member and employee on layoff, violated the CBA.

The District Court carefully reviewed the arguments of counsel and the CBA provisions at issue and concluded in a well- *135 reasoned opinion that the grievance did involve subcontracting and thus was not arbitrable. It also held that Lockheed Martin had not violated the CBA by subcontracting rather than recalling a worker on layoff.

For the reasons so ably expressed by the District Court judge in his opinion dated June 21, 2006, 2006 WL 1697179, we will affirm the judgment in favor of Lockheed Martin.
