Leading up to and during my furlough to have senior non-scab pilots bragging about what an opportunity this was to get 110, 120, 130 hours of pay due to staffing being so thin, and calling scheduling to help them work the next day's trips didn't pass the smell test either, so it's entirely believable to me that pilots eat their young, regardless of the carrier. But having a union is vastly better than not having one and wearing the pin has nothing to do with the name of the union but rather with the people in it, and the pin shows support for them even though some of them may not feel the same way.
