The work in question involves removal and. disassembly of control valves on an air brake test rack. On March 2, 1976 at Carrier's North Little Rock, Arkansas mechanical facility, a Carr::azi t,-as assigned to remove and disassemble 20 control valves on the test rac::'s panel. Specifically,, the Carman disconnected handles and cover plates, removed. ruober diaphragms, disconnected the compressed air source, and took the rack off the wall. Claimant asserts that this assignment- by Carrier resulted in the Cannan performing Machinists' work for approxiinatel"Y one (1) dour.

Carrier argues that Rule 26(a) which restricts mechanics' work to mechanics or apprentices does not restrict work to Machinists, but rather to those crafts comprising mechanics, and Carmen are included in that category. Rule 52(a) is the Machinists' classification of work rule. Our review of the cited contract provisions persuades us that the work in - question is not expressly reserved to Machinists by clear and unambiguous language.

When a claim such as this is presented, the-burden of proof is upon the petitioning Organization to show that the work in question is contractually reserved to employees of that Organization; or that by system-wide custom, practice, and tradition such work has been performed exclusively by that Organization. In the case before us, this burden has not been met. Even Claimant Berry's letter asserts only that Machinists have done the work at issue, not that it has been work assigned exclusively to Machinists. Carrier's assertions remain unrefuted that Carmen have historically performed the work in question without incident. Upon careful consideration of the record before us and the Agreement language we have no alternative but to deny the present claim. See Third Division Award 22244.
