$8$ technicians $($Service Department$)$

$2$ maintenance employees $($Building Maintenance Department$)$

$4$ collisions repair technicians $($Auto Body Shop Department$)$

$3$ office staff $($Office Department$)$

Each department has a manager, who along with the corporation$$s president and secretary$-$treasurer, make up the management team. All of the departments are located in and operate out of a main building except for the auto body shop, which is located in another part of the city about a kilometre distant from the main building.

Representatives from the Auto Technicians Union are currently attempting to interest the eight technicians in joining a union, and an Auto Employees Union also wishes to organize all of the employees as a local union. Only three of the technicians and none of the auto body shop technicians or office staff are interested in joining a union. The new and used car staff, however, has expressed interest in joining a union.
