I have not seen such a clause in the CBA, if someone could show us that it would be appreciated. Can you trust them, no. They will tell you something like that exists and point you to the source. You read the actual source and it says no such thing. They will tell you that is how it is interpreted, when it never will be.

If it does exist, does that mean it will be followed? The 2007 CBA required arbitration of grievances and Gojet routinely refused to arbitrate saying each grievance was not properly grieved. Then there would be an arbitration about whether GJ had to arbitrate. When they lost they still refused to arbitrate until they were sued. Then they claimed the suit was improper because arbitration was required. They will spend 3 years making that argument if they need to.
