Below is an excerpt from NMB Decision on determination of  Mechanics Class and Craft


I. Proper Craft or Class

In determining the proper craft or class for a group of employees, order the Board considers a number of factors. These factors include functional integration, doctor work classifications, terms and conditions of employment, and work-related community of interest. United Parcel Serv. Co., 30 NMB 84 (2002); Frontier Airlines, Inc., 29 NMB 28 (2001); United Airlines, Inc., 28 NMB 533 (2001); US Airways, Inc., 28 NMB 104 (2000).

It is particularly important that the employees share a work-related community of interest. Continental Airlines, Inc./Continental Express, Inc., 26 NMB 143 (1999); LSG Lufthansa Servs., Inc., 25 NMB 96 (1997); Airborne Express, Inc., 9 NMB 115 (1981). The Board makes craft or class determinations on a case by case basis, relying upon Board policy and precedent. US Airways, above; USAir, 15 NMB 369 (1988); Simmons Airlines, 15 NMB 124 (1988).

The Board has examined the proper scope of the craft or class of Mechanics and Related Employees in numerous decisions. United Parcel Serv. Co., above; US Airways, Inc., above; United Parcel Serv. Co., 27 NMB 3 (1999); Allegheny Airlines, Inc., 26 NMB 487 (1999). In United Airlines, Inc., 6 NMB 134 (1977), the Board, quoting National Airlines, Inc., 1 NMB 423, 428-29 (1947), described the composition of the Mechanics and Related Employees, in part, as follows:

A. Mechanics who perform maintenance work on aircraft, engine, radio or accessory equipment.

B. Ground service personnel who perform work generally described as follows: Washing and cleaning airplane, engine and accessory parts in overhaul shops; fueling of aircraft and ground equipment; maintenance of ground and ramp equipment; maintenance of buildings, hangars and related equipment; cleaning and maintaining the interior and exterior of aircraft, servicing and control of cabin service equipment, air conditioning of aircraft, cleaning of airport hangars, buildings, hangar and ramp equipment.

C. Plant maintenance personnel including employees who perform work consisting of repairs, alterations, additions to and maintenance of buildings, hangars, and the repair, maintenance and operation of related equipment including automatic equipment.

The related employees . . . while of different skill levels from the mechanics, nonetheless are closely related to them in that they are engaged in a common function the maintenance function. Eastern Air Lines, Inc., 4 NMB 54, 63 (1965) (emphasis added). It is this functional connection between mechanic classifications and those employees performing related maintenance operations that has historically formed a basis for their identity as a single craft or class.
