AFFIRMED.
Before RUSSELL and WILKINSON, Circuit Judges, and CHAPMAN, Senior Circuit Judge.
PER CURIAM:


1
District 17 of the United Mine Workers Union of America appeals a judgment of the United States District Court for the Southern District of West Virginia, which on cross motions for summary judgment, vacated the decision of Arbitrator Bruce Boals.


2
Arbitrator Boals had awarded the grievant, Donald Thayer, with probationary employment as a rock truck driver for Mutual Mining Inc., after Thayer challenged the skills evaluation by which Mutual Mining, Inc. denied him the position.


3
The district court vacated the arbitrator's decision to give Thayer the two-week probationary period, after finding that it did not draw its essence from the National Bituminous Coal Wage Agreement, which was controlling.  After a careful de novo  review of the record and the briefs, and consideration of oral arguments, we agree with the district court and affirm.

AFFIRMED
