The case you need to be looking at is Japan Air Lines vs. International Association of Machinists (1975). The court ruled that scope issues, in this case the issue of outsourcing, were permissive subjects of bargaining.
But the specific case is not important. What's important is what the NMB actually recognizes, and they don't recognize scope provisions as being mandatory subjects of bargaining. The reason for this is what the Railway Labor Act actually says.
Section 2, First of the Act requires the parites to: "...exert every reasonable effort to make and maintain agreements concerning rates of pay, rules, and working conditions."
Those are the three items specified in the Act as being mandatory. In other words, compensation (which includes retirement and insurance), scheduling, and related working conditions (vacation, sick leave, etc.). A grievance process is also required by a separate section of the Act, so that is also mandatory. Other subjects are permissive. You keep looking at cases and documents that pertain to the National Labor Relations Act, which has very different rules on just about everything than the RLA does.
Thank you PCL for your constructive input. I’m ready to admit that I was wrong about this issue. There is no question that there is a lot of grey area on this issue and it is still being tested in courts.
I did read the example you gave and it’s about subcontracting not mergers. However it does mention “scope”. It was also a long time ago and many laws have changed since then. The most recent example I can find is the Frontier/RAH case. The RAH employees failed to get a single carrier determination “(only the union or employee can petition for a single carrier determination)”. They lost because like us they are separate operating certificates but also because there was no intermingling of the companies. I know it’s a long shot however there has been asset swaps which could constitute intermingling. If a single carrier determination is reached then it would fall under Public Law 110-161 which is what the latest mergers have been using. A good article about that and airline labor mergers can be found here http://www.house.leg.state.mn.us/hrd/pubs/airlinemg.pdf
Since all of that is a long shot if people are interested in onelist, it would be even more important to hold onto PBS. It would be the only leverage we have to get the company to talk about it “in good faith”.
