Let us keep it simple...If these OMS's, Non Union Clerks, Dispatch Specialists are not eligible for the annual MIP, they are not Management. Filed grievances over this back in the early nineties over this issue, all I got was stonewalling from the Company and the Union leadership. The Company's solution to prevent any further organizing of these (Non Union Clerks) was to change their classification to OMS and the Union let it happen, either too weak to challenge or they didn't give a damn about organizing inside their own Units. There is a lot of history over what happens if these (Non Union Clerks) decide to join the Teamsters, it happened in my old local back in the early 70's. Back then all they had to do is sign a Union Card.
The major concern is the vested time under the Company's pension plan and their transfer into the Union's plans....but that is another topic I do not want to get into....
