"Courts have ruled that a dispute is minor if the employer's action complained of by a contract employee is "arguably justified" by the collective bargaining agreement."
The change of our 401K provider is in no way "arguably justified". The CBA is quite clear. It also entails far more than a dispute between a contract employee and employer. This affects multiple bargaining units and non-contract employees alike, and involves hundreds of millions of dollars.
We can argue the intent, individual interpretations, and personal opinions all day. The only way we would have known for sure would have been to file an injunction before the fact to cease and desist. We may have found the effort fruitless, but at least we would have tried. I'd rather use dues for more productive efforts rather than key chains and such.
Meanwhile, I'll dress warm, wear comfortable shoes (fully uniforn compliant of course), look sharp this coming 12th of December, and await the results of the path we chose to take.
Good thoughts here
